 Hello everyone and welcome back to my channel. Now as you can see in front of you here there's the Rygo DP832 sort of slash A and I love this power supply. The one problem that I have with it, one issue it has with, I have with it is this. I'm hoping you can hear it but it's the fan. The fan on this is like really loud. Now if I have this on and I have, normally if you have an oscilloscope on and stuff like that you've got two fans on the go that are quite noisy. This is when it's just in standby mode so if I were to put a load on this this thing gets even louder, quite a lot louder to be honest with you and normally with oscilloscopes their fan is quite noisy, the Rygo 1054Z, that to me was quite loud, that's one of the reasons why I bought this was because this one doesn't run the fan all the time, that's not the only reason I got it but it's one of the reasons I really like it. Now if I were to have this on the go and have the boiler on the go as well because look it's here in the room with me and even down there on top of the oven there there's an air fryer, I don't really use the oven at all, there's an air fryer there and it can all get really noisy in here and I hate that, I like it nice and quiet. So what I've got today is my last tack for this Rygo hack upgrade whatever it is you want to call it, nice boy sticking in, a different fan, I found that claims to go as low as 13 or 16 dB or goes as loud as 16 dB, I can't quite remember but it's quiet anyway, let me just have a little peek on there through the camera and I'll be able to see it as you go, there you go you can see the dB there look, okay so this isn't, it's not a loud fan and even though that at the back doesn't sound that loud at the moment like I say on the load it does get quite loud, so this is what we're going for, we're gonna put this fan into the Rygo and see how much difference it makes now before I do that I'm just gonna chuck a quick load on it, so hold on, okay so what we've got here then is we've got a power resistor, this is a 10 ohms 10 watt resistor and we're gonna be driving 10 volts for it at 1 amp which will give us 10 watts and if I put this on now you're gonna hear the difference between, I'm hoping you're gonna hear the difference because the microphone I'm using is like attached to me but hopefully you can hear the difference so yeah that's not very good example is it, so okay as the as that little one didn't make any difference what I've done is I've got a heavier load here this will be a 55 watts bulb and I think we might have to ring that up I don't think we're gonna be able to do it from 12 volts but let's just try see if we can put in 12 volts into this yeah so I'm just gonna say 12 volts and we give it the three, the full three while I say we can do this 3.2 amp, just to give it the full amount of current I can possibly do it now listen to this, so this starts coming on would you will, it's pulled it down because that's the maximum you can do it 33.7 watts but you can definitely hear that fan going can't you I'm hearing low really thinking about it's not too bad still I like the idea of putting this quieter fan in there it's going to do just as much work but it's going to be a lot quieter and like I say when you got this on the go when you do the boiler kicks in and if you're to have other things on here with fans in which I don't even my laptop even though it's got two fans in there it's very quiet really it becomes quite annoying so let's see what this is like and we'll do exactly the same thing when we've put the other fan in all right let's whip this apart this is what we're putting in all sorts of connected cables here these are three pins on this one here it's got three not quite sure what we're going to do about that because we've only got a thing for a two pin this goes to a two pin one of these has got to do you know I hope or I just disconnect the one off the other that's probably what we're going to be doing and just using the the two pin because we certainly can't put this on that three pin connector so let's do it again so how are we going to do this then and get it working but there's only two on here so I'm just going to nip this off here and I'll just solder and I'll cut this off then I'll just solder that on the end of there basically and not use the yellow if that's what's required I'll find out I was going to say I'll use my power supply and power it up to find out which one makes it turn but now I've got this in pieces I don't actually have another power supply there we go guys so that's back in there and just reconnect this with a heat shrink on there that thing's not going to go anywhere that it's going to be a problem so I'm not going to worry about that I'll pop that into that just twisting that way around those can't seem to get it to stay still all over it doesn't really matter it's not going to hurt on this that's that I'm going to just re-put this back in reconnect this this back on that that way through beautiful I'm just going to do a quick test make sure we're blowing the right way because we want to be sucking out sucking it out and I'm going to do I'll put this on here to microphone his face in once both feel like we're on a ship and all over the place power on slightly louder and his first beating up and settles down to a nice quiet sound again I do like that that's a big difference that's a big difference from here where I am is you got to listen hard to even know it's on or not you can see by the display it is but much better right I like all this back together again and yeah sit and sit you put it on there see what it sounds like there okay so here's the moment of truth which is put it on pretty good and stand by it's boot up noise we've got a bulb connected now this thing the microphone is on me because you know it's going to be here and for my ear level which is pretty much here and to be honest with you that's a massive difference I can hardly hear it I can hardly hear it that's a massive difference now let's give it a load let the fan start kicking in leaning forward a little bit yeah that's that's much more livable there was anything that ever that I'd ever swing downwards on this power supply for was that the fan could be quite noisy but that's uh that's good enough that's good enough for me any day of the week really really happy let's go back down to its normal level again fantastic absolutely fantastic I never fell out of love with this power supply but I think I'm more in love with it now as weird as that seems right cheers watching guys because it's par and I'll catch you in the next one
