 Yeah, so thanks, thanks for inviting me here. So, so look at me. I mean, we used to be colleagues at SP digital. So anybody know what SP digital does. Maybe I just sell a bit off. So I'm a software engineer and SP digital. So what we do is we provide what are energy tech solutions. I forgot the tagline ready. Yeah. Specifically, my side what we do is, whatever you see today on the SP utilities app. If you want to open and close your utilities account, look at consumption. We are basically building the websites plus the all the back end systems to do it that we also support internal businesses. For example, let's say automation today the meter readers technicians they are doing very, very manual work pen and paper to figure out let's say what are the meters that needs to be repaired and things like that. So we harvest the ingest all the data when we figure out and to use of various technologies AI machine learning to figure out what are the things that needs to be proud of that. So, so we work on all sorts of things that can help the device make to make the SP group is a utilities company operate better more efficiently and I think it's to save taxpayers money. Yeah. So, yeah, so that's why I do. So the topic I'm talking about today is hotline liquid cooling. So, anybody here knows what okay anybody here has built your own PC before. So is it, is it water food. Okay. So, so I was sending so I always been building liquid cool PC and I have my, my, my, my, I always thought my thought was like, it's easier to maintain is, is quiet. My, my, my aim is it needs to be quiet. So I realized that after my first few builds there was one bill I tried to go full silent, meaning that not no fans, all hit things. And then it's okay but you can't go very high and because, yeah, so, so, then I was thinking, we'll, we'll look at cooling actually help to that. Yeah, so, okay, so I will just try to wait. Okay, so we all know about traditional cooling. So CPU or some kind of hardware that's, that's warm or hot. You have a heat sink, which is basically something that conducts it away and then you have a fan, which tries to cool it down basically the fan tries to bring airflow through that. So I won't go into details like all whether it's positive negative case flow all these are all those are like beyond the score of this. So it's really small about my experience with what water cooling. Okay, so why because things like this are very hot. Right, so we need to cool this down. Yeah, so traditionally you can put things like that. So this one was one of my examples I tried this thing technically can run without a fan. This is the laptop D 14. So it's really really a gigantic piece of aluminum, like this. So with this, if you are not gaming, you can actually run without fan. Yeah, and you can really achieve almost complete silence. So if this one pad with even power supplies that are totally silent passive you can actually run an entire computer without any fans. Yeah, but obviously not for gaming. Yeah, so. So yeah, I understand that it needs to have a large service, but at some point that the air that you're trying to keep the air that you clean. Correct. Correct. So this this obviously need to put it in a place where there is adequate airflow, and because this is so so huge right. Without the fan, it your you have acceptable temperatures around. Okay, it depends on how as though you feel it is around 50 to 55 degrees. So you can survive up to 100 without open case shutting down. Yeah, so if you are not gaming, it's actually okay. Obviously this experiment you shouldn't be doing that. Yeah, but I'm just saying that with this size of fans right, you can actually run without fan you won't shut down. You will still run because it can maintain around 50 plus 60 degrees. Yeah, obviously not not this you try to get. Yeah. So I know that answer the question. Yeah. So us today costs around 100 and 180 90 I got this I maybe very long 12 years ago. So just to just in case. So not so as a company that I think they make one of the best hit things. They are expensive because they are really well made. And they last while in the sense that even over the different generations are your CPU socket all this might change right all you need to do is email them say that I have a new CPU socket. And which what house using they will mail you the the bracket for it. So in a way it's like lifetime you can use it for years I used to I've been using it for more than 10 years over like three or four PC builds. Yeah. Because I know that yes, you need to clean. So there is definitely maintenance, even though it's so-called fanless. Yeah, over time. Obviously if you're a fan you will see the fan marks there then you see you to maintain. Ultimately, it's still there's a maintenance. Yeah. Okay. So, so yeah, yes. On the photo we show that so that we can see. Yeah. Yeah, you can you can. I mean, I'm not, not saying that we should run fanless. I'm just saying that is, it is possible. I haven't done enough experiments that you can issue on finance but but yeah. So, but this is just to show but it is usually is in the case. I'm just going to illustrate are in case for the rest who are other parts of the PC at today's today are the same, whether it's graphic cards, or what is always sitting fan even today, your mvmv SSDs also has a mini meeting he's saying and fan. So, yes, so everything now has your even your memory sticks now today has a headset and a fan. So, pretty much now everything is getting hotter, because they're getting smaller and. Yeah. Okay, so water cooling. Right. So, what's the concept. The, the, the heat sink is replaced with a water, what we call a water block. So it's actually jazz metallic aluminum and some kind of metal block that conducts it away. And the rest is actually like any other traditional heat exchange. So what cold water comes in, it goes out. The water is being passed through a radiator, and then the radiator with his, with his large facility will will try to put down obviously you can put fans on it so that you can put them in the apartment so to actually submit the, the coolant. Yeah, coolant here can be can be a lot of things some people say that water works for obviously water over time they will they'll be out gay growth and things like that. So people will use something called some kind of coolant. So they usually what does willing to water clean companies they sell it. So the next point in it will inhibit the growth of algae and basically try to clean things along the way. So, some people claim that you can just run with pure distilled water. It was for some people it was it depends on where you are in the in the world so then basically maybe it's okay maybe our environment is even some countries that even the ambient temperature is low they also have to put in some other chemicals make sure that doesn't freeze like this. Yeah, so it depends on where you are. Yeah, so in case, in case you wonder why it's a water block like it, it looks like a mini hit thing. So it's this is a cheapest that you can find so you have a copper plate and then there's a lot of things. So it basically tries to mimic what a heat sink would do. But in this case, it passes water through so water in water out. So that that that that that that's how what to clean words to try to cool this water block or quite cold plate. So, this is the most elementary one. Obviously, today you can buy really nice machine once very very fancy that really with tiny things different channels that forces the water through so that's that's a up to the design of this. You can go through tiny things that can make the pressure higher and things like that so there's there's a lot of science that they they went into designing modern water blocks. Yeah. So, next thing is what case and form factor, if you want to do cooling because if you want to do water cooling then you, you can get to there you can pretty much buy any any kind of case you want. So I think traditionally in the in the past they are some. Okay, you still need to buy and accommodate so I'll cover later on what do you need to figure out to see what fits based on how much components you have. What is the way for size of the radio you have then you have to really go and consider what is the size of your casing. So, you can also you can go all the way this really fancy kinds where these are called like a medium or small compactors they are really custom if you are really into this kind of thing you can buy cases these are these are not full custom meaning that it is still off the shelf. They are those really really hardcore ones they machine, they machine their own cases, but this one you can buy off the shelf, but it was a lot of manual. So, yep. The case alone is $700 just the case without any components just the case itself. Yeah. So, okay, along the way, I will cover then you can you can feel free to ask me the prices. Anyway, why I remember is from two years ago. So I built mine during Kobe, which is probably might be higher than that now. Yeah. Okay, next is, you can also go, they call it SSS, SSS small contactor so traditional small things that is because it's really so small people might say that maybe my thing you can't you can't fit any more water components in is really so small but apparently people have done it. Even for this kind, which is so small, you can see the mouse for comparison they are able to fit in water cooling for both the GPU and the CPU. So, yeah, people have done amazing things with it. Yes, yes. So it really depends on what you're willing to it's a it's a it's a balance. If you are running a large big case, you can afford more fans more radiuses, you can put you can get a very low. If there is something like that right it's very tight definitely f o it will be will be worse. The, the, the, the, there's only one way to do here, but it depends on what you're going for. For example, let's say your you want to go for a quiet you want it to be small. You can say that I am okay for this to run at a load of let's say 80 degrees, maybe for someone who's going for cool and quiet they may not accept that so it really depends on what you're aiming for for some folks they want the size. Yeah, definitely if you will echo this you won't you won't be able to fit high confidence in but if you want to quit you barely allows for it so it depends on what you what you're looking for. So, if you're looking for like for this maybe they are designing this for cat and maybe video video editing maybe not so much about gaming, and then people actually underclock or limit the voltage limit the hardware so that they know that it can perform better, but they make it more efficient by maybe limiting the power consumption to a certain voltage, and then you know that the pressure won't won't exceed that. So again, that's another whole science of what they call today. And underclocking technically overclocking today is. I won't go to that. So that that's that's how you can actually optimize optimize it. Basically, you know. Yes, yes, I'll cover that and what I did so this is this is not this of mine is often that so yes. Today they sell GPUs already pre comes with the water block, or you can buy and then you remove and you buy a separate blog and you can. This is the more traditional one is what you can buy off the shelf. Yeah, so I think this is aftershock so if you today because they know there's a demand for machines like like this right, you can buy off the shelf they pre build it for you and then you just ship to your house like any other they'll complete the house. Yeah, so if you want some one of what the PC but you're not you you don't want to get your hands dirty you can actually buy all the shop today. Yeah, so I end up going with a more traditional PC tower case like this. So to answer a question earlier that I wanted to it to be running cool and near silent. So definitely I need something bigger I need more space I need more really intense. By the way, this is, I think it's an attack evil acts if you're curious. Okay, how much it costs this case I think it costs trainers. I think more than this nowadays and there's no fun. Yes, because today there is pretty much no need for this. Yeah, so there is a front I always thought about this whole thing can be removed is just a faceplate but the behind is just a pen for for fans. Yeah, so if you again is not mine but this is what is fully installed is something how it looks like. Yeah. So, although it looks quite plain you can look quite cool when it's fully loaded. Okay, so the question is if you have decided that you want to do water cooling, whether to go half hard line or soft to be so direct internet recommendation is you go soft to be so to bring is pretty much the garden hose idea. So the good thing is, which I will talk later that the pain of hard line is everything doesn't move. So the total tolerances are very quite high. So any King or any, anything that's not a line. There will be leaks. So soft is really just a to be a coin to one end. Usually nothing will go wrong for hotline is it looks nice, but you really have to figure out how do you measure it to be precise because you can imagine. You are just I want this to point to this. How do you even make that happen. How do you measure that to cut it to the correct length. So, the worst is, they are different types of tubing which I will cover cover. So there's a few types which is required rubber tubing here so rubber is the easiest so what they recommend for stuff for starters. Yeah, then you have acrylic PDG, various types of plastics, you can go glass. If you know how to bang glass. Yeah, you can go other exotic stuff like copper and even carbon fiber for some folks. Yes. So, I went a couple so that I will show. So, so the thing is, you need to bend things. So you have to think about how do you bend things is you are going for class how are you going to bang glass. So if you can bang glass at home, you have to, there are guides on this but it's really really complex. You can bang copper so, but today they actually sell pre-banned copper which I will show so they are pre-banned in 45 angle degrees. So you need to bang yourself. Yeah, but for for acrylic on plastic, you have to bang yourself and it's actually not that complex. It's really just a heat gun, which is pretty much a head dryer. So you have to be on top and then you just what we are there is often and then you bend it so obviously there's more to that you have to put inserts in. If not, if it's a hollow to the moment you bend it gets collapsed. Right, so they will put rubber inserts into today. So again, there's an add and sign to all those but I won't cover that. So, recommendation is if you are totally new and you will try to go for rubber tube, if you have one to review one to experience or have try more things, you can try acrylic or plastics. Yeah. Oh, okay price rubber tube is cheap. I think three meters of rubber tube. Okay, obviously it's not normal rubber tube because rubber tubes will be great over time. So those views of water playing because water runs. I think they sound slightly higher quality ones. So I think a three meter tube set $12 plastics and credits I think they sell in one meter length. $1215. A lot of things actually I saw online, you import from Alibaba or this is this is cheaper. If you try to buy locally in Singapore is a lot more expensive. Okay, so the next part is how does this actually connect to that water block or thing that we are talking about. So there's this thing called fitting. I always wondered how they connect. So this is called a fitting. So fitting means you can imagine there are two parts. The bottom part is the one that actually screws on to radiator or the water block. So you can see there are two rubber seals. So what you have cut the length that you just force it in the rubber tubes to so called provide a seal. There's outer ring so when you screw on the outer ring it locks it into tightens it into place. So that's it. Therefore, by squeezing the rubber tubes into the metal you achieve a seal. So that's how how you connect things to parts to different parts. So they call this fittings. Yeah, there are different types because if you're using this is for hard tubes, things like copper or acrylic. So that design is for rubber tubes. So I think I think you can guess it looks more like a garden hose kind of right so that's actually for rubber tubes. Yep. Okay. Okay, I think the next part is, which is the planning part. So this is a rough thing diagram of what you have to consider in planning. I would call it a cooling loop. So before we go on one pitch next. Okay, in a simple design, what these are the minimally minimally with these other things right. Let's see. Okay, this is, this is when the in the past battle to build us to popular. So you definitely need radiators radius are the one that actually water goes through them and then they dissipate the heat. You need a reservoir. So, okay, reservoir is I read why reservoir is because if it's just Today they sell close to coolers. So it's just a radiator. The tube and then it's just a coat of the water block and then you kind of CPU. So technically then you are best available so actually it's no reservoir because it's close to But however, if you are building yourself you, you wouldn't be able to fill it up to the brim without having a reservoir there to store water. Yeah, you can do without it but I think it will be a challenge to to to fill everything to fill the entire look because your look is of different heights. How will you get the air out and make sure that the entire thing is fully filled up. It's really good. So you need a reservoir. And I think for aesthetic reasons people hook as well because it was cool. Yeah, so that's a reservoir you definitely a pump. Yeah, I think I think that's probably. Yeah, so, so going back to this then there are more things which is, okay, this are more like serial product because if you look at any, any, okay for GPU in case in this sense, there's a in that's out. So do I go in and out there or I go in and out there so again this is more of design and choice. So, they talk about the things how do you bend it because you can go 90 degrees you can be fancy you can go so all this you have to really consider the design, the reservoir drain well so there is maintenance. So things like maintenance can be a problem for them for different reasons. For example, the coolant, technically they recommended by the manufacturer that manufacturer is that you need to change the water out maybe once every two years. Yeah, to make sure that there's nothing going inside. But even if other things for example, your GPU sunny dice, right. How do you remove it and then send it for I may also this thing. So you can't, if you just plug it what does it just personal right, so you need a drain off. So the drain off is for you is just located at the lowest part of the of your of your build. I mean that can be very fancy designs like push pull walls and stuff like that but it's basically that so the idea is you if you need to drain it just open it and then you drain it. But the thing is, again, even if you open it. They are high low parts you won't be able to train everything. So you still have to do some kind of leading where to somewhere on top again power design pump air in to get for all the water out. So, so if any of us if you're curious that yes there is maintenance involved but I think it's it's not that bad for my mind I think I did I did it once it wasn't it's not that difficult. So if you design it probably you just train it and then do any maintenance you want to feel about the back. Yeah. So you can see the lines they come back here like you need to consider things like if it's the run is too long with it said. Yeah, is it rigid or this so. Okay, so so this is a different different constitution so I will try to cover later once I go into the photos. Okay, so next let me just go in. But I didn't prepare enough slides, but I will cover photos. Yeah, so this is the case. This was the planning that I did for for it. So I have to consider red parts are the radiators. So I, again, I don't have a cat diagram. I don't have a cat file for this. So I have to really do a lot of guesswork. I will, I will scale the image to the correct dimensions. Again, all this is very hackish I will scale it to the correct dimensions of what I know the case is. And then fill in the gaps so in Photoshop make it one to one so then after that I will draw out I know this is the radio they're going to buy what is the length. Does it fit. So the red parts are radiators blue parts are the fans. So again I look up the fans back how long is the fan. Okay, those are those are fixed, meaning that if you're radiators supports three fans, the holes are really great. So those are the things we don't worry. The thing that you worry is connecting all these things together with the part running from there to there. How long does it have to be. So, so, in short, what what what I do is I try not to then stuff because that would be that will make it really really funny because you connect one part and then you then how much do you know where to then. So for mine is easier. I try not to do anything. I buy prevent stuff. So you, you cut one side to make it the other side then so now you just worry about one side. I don't know if I said it's a good explanation. So another day, it's always the case. Cut it first. Then later on. Here you have to sort of high balls. So I will try to cut not not so much. Look at it. Try. So that's that's that's try everything like that. So I actually have to cater and buy more. So you do make mistakes. Once you cut it to short is it's gone. Yeah, you probably can reuse it somewhere else if you're shorter but yeah that's a lot. So that's the pains of hard hard life. And then the thing all these things like to make them treat nicely they are definitely the things that will actually help which I will try to cover later. I have to count how many I have to buy and how many how many had to wait for a few things for the angles. I end up buying like four times. So I bought one batch and try to fit it and right. Yeah, you need more parts by again by again the whole building I think took me like probably six, six months. Because a lot of shipping shipping from from from top our channel takes easily two weeks each. And then she should be the wrong stuff and things like that so I have to do this. Yeah, so. Okay, I'll roughly go to the part so this is the water block. So some pictures. Yeah. Yeah, this is important, you know, before you always see a sticker on his things fans, people always forget to remove that protective sticker. Yeah, even OEM companies they'll they make it mistake so their customers will say why my CPU overheating then when the repair person opens it up they didn't remove the sticker. Yes. So it's the blog. It's the brand. At that time of this I think Ryzen 5900X was I think it was one of the best value for money today. There are choices but it was it was. Oh, great price. Let me go back to this. Let me try to remember things like that. Okay. This blog is things to 80 $280. I think it's around that I think per stick is like 150. 8 to each. I put four pieces so 32. Yeah, I don't need to support because gaming and most very few things in the process for unless you're running at tons of virtual machines doing really. Yeah, this one I think I bought a really small one is only 500 gigabytes. Yeah, I think this was like probably 200 plus. Yeah, CPU. Wow. I think it was 2002 at a time. Today is a lot cheaper. Yeah, that one that was a time that every was shortage people are robbing other countries people are delivering CPUs in armored vehicles that was a time. Yeah. So, today is a lot cheaper motherboard for $500 I think. Yeah, this is the socket. So in the day for six of them again, that time was limited by choices. There's a lot of things that we really because it was I think just after one of the face to really a lot of things unlimited. At the limit of price. This is a it's a it's a it's a the water block for the GPU. So you can buy your own GPU remove the the the his thing that the one that comes with it and then you can buy something like this to revisit with. So I actually bought this thinking that I can buy a GPU. For nearly four months I couldn't get you. I exhausted all my contacts because I have contacts working with distributors and then at that time, really nobody can sell a GPU. Yeah, you have to pay like really through the roof like three four times the price. Yeah, even distributors themselves are trying to sell sell off without even going through so pretty much you couldn't get it for you couldn't get what you want. So you pretty out you have to really see what's on the market and then see what fish of budget. So I even though I bought this. I end up returning it because I couldn't use it because I couldn't get you that that that fit this. Yeah. Oh, wait, so this cost. Around $300. Yeah. Power box hundred and hundred and 80 something. Yeah. So the people might say oh you today you need a hundred watt power supply for what do you know you don't actually you can there are ways to compute it. So today efficient power supplies actually you don't need that you don't need to use you need to go like really over over the top. It's modular so you can really have good people management. Okay, so this is a pressure tester. So after you have done out your look right the only way to test that it doesn't leak is to connect it to a pleasure to pump out a pleasure. Because if it doesn't leak air means it doesn't look water. Right so so that's you have unfortunately you have to either you have to buy this to be able to test your system and if you since it might seem like a one time purchase because you use it once right but each time you do maintenance you have you should actually test it again. This costs 30 bucks. Yeah, so you can see how many bars you can test it. So if you if you pump it let's say so the recommended not that recommended pressure that you should be for for water is the pump it to like 0.7 or 0.7 and you lock it you hold it that you put it for overnight. If it doesn't drop means good. Yeah, if the next day you see oh it drop means it is leaking. Yeah, then you have to figure out where it's leaking that that's actually the hard part so so how to figure out where it's leaking right. So there are there are a lot of ways. Some people say that yeah you get you get soapy water, you brush all the connecting class. If you see bubbling then you'll notice anything but especially this thing this kind of the leak might be very very very little so sometimes even those can't detect so sometimes really have to try and like for me it when I first call it installed it was it was it was leaking. Then I just remove every part pulling back again again I didn't go to the bubble support the rock. Yeah. Okay, these are additional fittings this is to mount the pump and reasonable. These are the radiators. Yeah, so they look like that looks a lot like a corner courageous so it's just a lot of things what goes in what goes out. Okay, these are the hard tubes that bought so they are copper tubes that are pre chromed into a nice finish. So they look like this. Yeah, so they are pre bent one so so so So let's say I need I know what's the distance between my the certain device to that Ben, then I would just do a cut there. Then once I fit it now try to eyeball their side by cutting this by bit by bit by bit. Yeah. But these are fittings so even for a similar piece of PC you need to buy color fitting fittings are all the connectors, something connected something something needs to Ben turn all this I actually bought quite a lot I also bought spare just in case I screw up. Yeah, so they look like this. Yeah, so there is a one that this is the outer locking ring that locks in place, the other part on top is the one that actually connects to the device device you want then that is the rubber seal. These are connectors like 90 degree bands so if you are not bending something you you have to pipes just connect that using that. So that is just this and you seem to put a fitting on the way. So that's why the fitting multiplies to a lot because this is just a band you seem to put fitting on both hands. So these are more extension so I have a short gap or run some instead of putting a tiny short tube I can buy something like this. Yeah. This is a temperature sensor. So by having a gap somewhere you can actually use this thing that looks like a fitting but however the other end actually connects to a temperature sensor. Yeah, so that's interesting part so if I wonder, so how do you know whether it's cool. So you don't need you. Okay, yes you need to care about your CPU and GPU but all actually you care is what is the coolant running at. If you can coolant coolant pretty much everything takes care of itself. So, because obviously if your CPU and GPU is running hot, it will heat up the water the water will be hot. Right, so if you can maintain the water temperature to the temperature you want pretty much everything takes takes takes care for itself so all you actually need to do is to measure the water temperature. Then if that is within your acceptable range, you don't really need to worry about what CPU or GPU temperature running at. I mean obviously if I work walking. Yes correct to reach equilibrium then you have to do so so this one is obviously you have to wait a while you can benchmark and test it yeah so this is very important. Yeah, sorry. Yes. You okay so the pump, I will go to the pump. Yeah, so this is a CPU. So that's a that's a paste that came with it. I find the paste. Again, there's a lot of debate how we should buy the place is it a dog is a cross is it. Yeah, nobody can agree with it, but I use the traditional credit card with it. Yeah, so you spin it with a with a card. Yeah. So this is the other side where you have to remember sticker is this yeah it's quite shiny. And then you install it. So if you buy radiuses of a minute radius they are they are actually quite dirty because they are all you can imagine the welding and stuff that requires to manufacture inside is full of metal shavings and dust. You have to rinse it and with with with stuff to clear everything out rinse it a lot of times palm water through it so I was trying to clean them up before installing. Yeah. These are the fans. So I have two radiuses one that can fit two fans one can fit three fans. So I have to buy five fans. Yeah, this am I am I a word. Okay, yeah, so this is what I have. I have a set up then without any of the after after two runs yet. Yeah, because there was a delay of four months when I was trying to hunt around Singapore to get this kind. Yeah. So, yeah, so a lot of this which and I like I couldn't use I have to return this. Okay, this is okay this is the the fans that I want to install on the radiator. This is the pump and reservoir so today you can buy two in one so this is the rest the pump is below the reservoir is on top. So, to answer your question earlier that this pump technically works like a fan, you can connect the sense the pump sensor. The sensor tells you the reading. Okay, typically fans with a right, the, the, the, if you connect your mother what you can you can get to things because they powers attend. Secondly, it tells your mother about how fast your friend is spinning. Right. Yeah, so this, it will tell you how fast the pump is spinning and you can also control the pump speed. So by pairing your temperature you can you can say that if the temperature you can you can they call it the fan curve optimization. So if you say that if I wish you temperature run the pump at this up yet. There are software today that actually does this for you, you can just say calibrate it will based on a microphone, it taps your microphone it figures out how loud your fans are how much temperature and then you can calibrate this for you. Yeah, you can do it yourself in one. It depends on what you buy. So if you buy. Okay, so this is under and usually it's called is by your motherboard. So this motherboard, most of them support fan curve optimization. Oh, you have to buy the microphone yourself, and you have connected. Yeah, yeah, yeah, yeah, yeah, yes. This is not fun. No. Sorry. Yeah. Yes. Yeah, so, so because, okay, I'll go to quite part because combat the echoing right, you can run the fence at super super low RPM. Yeah, that's the main main thing. Yeah, typical fans CPU fans are running at 2000 to 3000 RPM. This fence on the radiator I can run at 500. It is so slow they can see it spinning. Yeah, it is really there to have some airflow that's it. Yeah, so you said that the is the palm is in cold by the water board like in the temperature. But I have trouble understanding that they might have this water in some system and there's some radiator and there's something that produces heat. Faster. If the water must sound faster. How am I going to eat. Okay, I don't know the science behind that. But if you push water fast enough through the whole system right. If I'm not wrong. That's what they say it gets cool down faster. The water go to the top of the city. Yeah, yeah. Yeah, so yeah. I think it brings to the right. Faster. I. Yes, correct, correct. Yeah, so that it's not in that sense. In fact, in fact, there are a lot of things in water that doesn't seem to make sense. Which one should come first. If I CPU is hotter and then GPU or GPU is hotter CPU should it should my should my look goes through the CPU first then the GPU with effect. So there's a ton of experimental science into that apparently doesn't matter. Yeah, as long as the loops temperature is what you want. Yeah, in a way so so there's really a lot of different things in this again it goes into science of science behind what's the science for for what the Yeah, there's a lot of fun with it. Like I will say something doesn't it's not very interesting, but apparently it works. Yeah, so I think I think that's another topic for why why it works and how well it works based on this. Yeah. So, so today, my today's motherboard has a temperature sensor for water cooling, the modern mother box today. Yeah, so there's a liquid like pw something that you can connect that. Yeah. So, this is the, I think this is something aerated to keep it to prevent the bubbles of forming. Okay, this is the GPU that I'm buying. It's not exactly the one I want but it's the only one that can get it. Okay, this is 2500 points. 3, 380 GTX RTX RTX 3, 380. At the time most of the line, there's no ti out yet there's no, there is 390, there's 390, but you have to pay, you have to pay almost 4,000 for it. Yeah. Yeah. That time was really nowhere to find it. This is the cheapest I could find. Yeah. Even outside buy it. The, the, the shop will tell me if you buy it now you will still have the money if you sell it at the end of the year which really it went to what it picked at almost 3,200 something $300. So this one is kind of this one ever has has this thing this thing to detect any leakage if there's any leakage it knows it will shut everything down. So there are metal tracers that will be back leakage. The back. Because I want to mount it very fancy I'm going to mount it horizontally so you have to extend your PCIe this standard aesthetic. Yeah. This is mounted. Here, here, here, here. So this is where I try to measure it. So what some of the tricks I tried online is you get a wire, those are quite the wire cleaner, the type cleaner, because they can bend quite well. So you use that and try to measure because you can cut them to length you can try bending it and then you use that to cut off tubes. Yes. Yes. So how do we cut copper tubes right. So if you have work with this is the same thing that promise used to cover copper tubes. So if you have done have your account installation done they are using the same thing to cut. So, it looks like this you. I think I have it in a later later slide. So this, this is just a radiator with the fittings installed with the pen installed so this is ready for connect connecting. This is the digital sensor display sensor. So this little show the water, when water runs it differs both the temperature, the rate of the water flow everything is in state here. So these are weird fittings that I have to compensate. So there are certain parts where these two things doesn't align this thing actually swivels upon a point so you can share two things and then you have instead of trying to figure out how to align them, you, you get this and then you will do the opposite. Because this thing can consume. So there are all these small parts that can help you achieve that that alignment. This. Yeah so you can see I already installed certain parts already so this is connected. So you have this device you, you, you press this thing this is a metal blade here. This is a roller. So behind that is, is a school that you can turn it will put it will put pressure on to this and then you just keep rotating your method, your copper tube. And then you will do a small groove. So you tighten it a bit, the one more round time it will eventually you will come through. Yeah. No, yeah, I mean, you can buy the expensive one that can do it but this is this is this is this cutter is like what $7 manual cutter so you just apply pleasure rotate. I don't know. It's like eight tubes. Yeah, but it counts it's bad. This one more or less installed you can see I have to do tricks here to try to get the alignment to see, you can see the weird band there so there's a lot of these things that you have to try to make the bands align. I mean fit. It's more or less done. This is the. Oh, this sense if I'm not wrong. Maybe seven bucks, seven, eight bucks. Yeah. Or maybe it's even cheaper, maybe five bucks. Yeah. This is the, the outlet valve. So in the, it is a, they call it a push pull. So all these are actually just pumping concepts if you do pumping then I think pretty much copy everything they just make it look nicer. This is $20. So I was testing pleasure I think this is dropping. I did a test run with plain water. So I, I, I, I, they always say that you should actually put paper towels in all the parts so that it doesn't leak by tested if my the, the, the, the, I tested with the pleasure tester few times everything okay so I just just went for it. So, so one trick you say is, don't connect the motherboard power just the look. So even the look leaks, nothing is on for this time. So you can actually connect just the power that delivers to your pump and thing and reservoir everything else is short circuit it then you can actually get it running without having to put it on. Yeah, affordable no. So you can use things like mineral oil or things like that. But they are quite visible so you can do it, but you can so there are things that that, okay, the today today they are, they are really interesting solutions right where they make it such that you almost never leak. So even if you try to slice the tip you know how how what it does is maybe I'll cover that. The one is very interesting way how they do it. Yeah, so this is like that up. Yeah. Yeah. This is the outlook ball. This is the, this is the coolant. Mistake for it is supposed to make it like cloudy as it is the stock version of it so yeah, it's really really heavy. This is 25 kilograms. Yeah, because it's all copper. The GPU, the GPU itself is, I think it's 2.5 kilograms. So the whole thing is copper. So all the copper pipes all this the way out the radiators or everything is copper for all this as an exam. Yeah, you can buy aluminum fittings from everything. So there's something about in metallurgy that you cannot mix metals because the ions will transfer they will leach out each other. So if you want it to be aluminum, the entire look has to be aluminum. If you want it to be copper, and that has to be copper. Yeah, so I decided to go copper out actually copper cheaper aluminum. Yeah. So, but it's just you have to, yeah, and it's very, very, very heavy. Yeah, so this is the sensor that I talked about. So the top one is the temperature of the water of the coolant water the middle one is the flow how many liters per minute. The last one is the RPM of the of the sensor. Yeah, so pretty much I because it's mounted just at the side I can see who I just actually occasionally just glance at it and I know everything's fine. Yeah, if you see the water is not flowing, then something is wrong or if the temperature is too high. So, pretty much this is right if I don't think it's around 30 degrees sometimes even lower if I turn on an icon, they will be around 26 degrees 2028 degrees so it's pretty much room temperature. Then gaming, it hits up to 40 degrees. benchmarking which I would say sometimes it's unrealistic, it may not realistic load on this is a really a maximum so benchmarking those markets of that it will hit like 55 degrees for for my yeah. So typically if if it's idling it goes like 0.7 liters a minute, if I revenge market, it will sheet probably three. I think that it makes up that fall. Yeah. Okay, so this is this. Yeah, so I went to buy this huge monitor. Yeah, so this one is the Samsung Odyssey G9. So if you have a GTX RTX 890 you need an equivalent monitor to harness and to use all the power. My table spans the entire room. It's a it's a inbuilt table under in the room. Yeah, so the the length is not an issue, but it's so this is actually, this is a 5,100 and 515120 by 1440 is basically 22k 22k monitors together. Yeah. I think the aspect ratio is like 21 by nine or something. Yeah, it's really, really good for productivity because you can really like open like four in those I think. Yeah, and it's even better for gaming. Yeah. Yeah, I think that's, that's, that's, that's all. Yeah. Thanks. Make a guess. Oh, wait, it's doing the monitor right. Quite close. Yeah. The graphics code alone is like 1.5k. The CPU was 1.2 motherboard was like 6700. All the fittings cost a lot of money. Each fitting cost $4. I bought like 30 plus 40. Yeah. So I think I spent around 5.5k on the CPU. Okay, so everything, actually the monitor. Yeah. Yeah. Yeah, I might reduce a bit but I didn't, I didn't really go over by quite a bit. Yeah, I was really, really careful. So I probably only wasted one or one or two of the fittings and then the tubes I think I wasted one tube. Yeah. So, can the cost be lowered? Yes, you can. Don't go copper. A lot of things can you can save on a cost. Can it go higher? Definitely yes. Yeah. A monitor was 1.5k. Yeah. Yeah, which is actually okay today if you buy the same model this or this Odyssey. This runs at, it's not that fast. So it runs at 100, it makes up 120 hertz. So the Odyssey G9 today makes up at 240. That costs almost $3,000. Okay, that's all I have. Any more questions? No, nothing so far. Yeah, then the sound. Yeah, so I measured with the decimeter. This is nothing on in my room. It was 22.4 decibels when it's on is, sorry, is it 26? Wait, let me see. Yeah, it's 26 when it's on. Full load. Full load. I did the picture here but I think it was not much difference to 28. Yeah. And pretty much you can't really hear it. Yeah. So what's the performance increase or the performance increase? There's no performance increase. Yeah, you probably can go higher in terms of overclocking but the main difference really is I would say you can run cooler. It means that you can change it overclock more if you want. Yeah, it is, you can run it at a much, much, the fence can run slower if you just small silent. So if you ask what's the benefit of how I'm cooling over, it's not really for performance. It's really just, it's for aesthetics is to cool things better. So you can definitely things run typically your CPU for echo CPU, today's CPU is easily run at 80 degrees, even at idle is like 70 degrees. But this for my idols at maybe 40 plus degrees at low is around maybe 50 plus max. So the benefits are, I would say really aesthetic and then if you want silence like me, then yeah, performance wise. Yes, if you are thinking about that, since it's cooler, I can overcome more, but then overclock is, yeah. Yeah. Okay. Thank you so much.
