CPU Lapping test - before and after temperature

[ApSykesThewolf]

OH MY GOD, that's even shiner than how i was able to get, do we really have to use lower grit to higher? i used 600 -> 800 -> 2000 grit

[hasmo151]

what for program do you use?

[Scavengecore]

tsssssssssss the vcores were different.. fail...

[FlossBandit]

any time i've ever touched a cpu, i've handled it like a stick of dynamite so actually rubbing sand paper on it blows my mind...

[braianascua]

what happens if you lap only till you expose the copper and stop there?

[deuketc]

@braianascua Hello, at that point it may still not yet be perfectly flat, which is what you want to aim for. This will give you the best contact to you CPU cooler

[braianascua]

@deuketc Yeah i kinda thought that its kinda hard though cause i am doing it to my ps3 and the cpu and gpu is connected to the board. thanks for the help.

[pakkiaman2]

@braianascua what's the black paper used for the lapping ??

[braianascua]

@pakkiaman2 it is sand paper

[pakkiaman2]

@braianascua thank u bro

[fastvedub1]

Anyone else notice that the vcore temp was lower on the lapped test result.You can see it on the asus monitor.Its not much but enough for a few degrees c.Very nice drop in temps though.Will be doing the same to my q9450 now.Nice vid.

[GT5Enthusiast]

You do realize that the outside of the motherboard wrapper is static right?

[Prowler1]

so the total average overholle core temps are. before high temps =237c low temps =114c after high temps=176c low temps=99c gain in percent is in high temps = 34.6% in low temps = 15.1% nice results, wonder how it will be in air-cooled system.

[ibanez1andrew]

Where you maybe a little bias with the thermal paste?!

Those lapping results are amazing.

[kokfah]

i thought he is saying.. "stopping the tits...." O_o

[cryingmushroom47]

@danthemanzizzle rofl

[rossroxabc123]

holy cow, that did so much better then i thought it would!!! awesome!!!

[nipdrops]

TIIMPERATIIRE TIIST lol

[SyLoWNiNe]

Results were with the lapping of just the cpu correct, not with a lapped water block?

im seriously concidering this.. since im getting high temps at 4.2 on a i7 920.

Awesome video!!

[deuketc]

@SyLoWNiNe Hi, yes i used my D-tek fusion 2, not lapped. Cheers

[lillskiten1337]

@deuketc well is it good to lap the waterblock as well?

and is there any 5000 grit sandpaper?

[XenatR]

@lillskiten1337 regular a4 plain paper is about 7000 grit

[lillskiten1337]

@XenatR hehe ;) sounds good to me xD

[lillskiten1337]

Respond to this video...  Can i ever use paper to sand the cpu XD HAHAHA

[diapysik]

@SyLoWNiNe My mind exploded when I heard you would lap an i7.

[SyLoWNiNe]

@diapysik

Hahaha.. Would?? I did, but no luck high temps haunt me still..LOL

High voltage batch of i7 920's i guess.. wont run lower then 1.450v stable @ 4.2.

[diapysik]

@SyLoWNiNe My mind just exploded because it runs on AMD and needs an i7.

[o0oHeavyAVFo0o]

2:17 slowmotion xD

[9AndS]

maxishine?

[deuketc]

@9AndS ?? I know of Maxishine.... Seen a few of his vids on youtube.

[devtech]

@deuketc i think he meant u sound like him

[jpmorgan187]

excellent video, thanks.

[onegreatamerican]

wow what a diff. i thought it would be 4 to 5 degrees at best.

[AggressiveNapkin16]

Thats always just a scary image in my head, sanding down your cpu haha

[cisco760ca]

I always lapp all my home cpu's and add little as i can of thermal paste . I get awesome low tempatures .

[mipjevdee]

Did u lap the cooler?

[deuketc]

@mipjevdee in this test i was using a Dtek fuzion waterblock (not lapped). Before that, i was using a termalright true120 and i did lap that as a test run, just to get a some practice before i tried a CPU.

[Rapagangsta]

System temp was at the beginning 40C, after lapping it was 35C.

[kanapathy15]

omg thats like 20 degree cooler!!!shit im gonna lapp mine 2!!!

[boreu2death]

The temp. difference is insane! Instead of buying a more expensive cooler, people can buy cheaper ones and lap the surfaces isntead, Great video thanks. Will definitely be lapping my processor.

[taimoor006]

@boreu2death yeah but warranty is voided

of course i don't care mine is lapped even with the water cooler

best way to get bang for your buck 5 bucks of sandpaper worth 10 degrees

[pratt123]

@taimoor006 Actually, lapping the CPU but not the CPU cooler is rather useless. Just lapping the CPU cooler (which has much worse imperfections) can result in a 5-10 degree Celsius reduction. Doing both is the most useful although you have to also apply thermal compound in the right amount and manner.

[12unnn]

did u overclock further than 3.2ghz after lapping?

[12unnn]

did lapping/lower temps allow u to overclock beyond 3.2 ghz?

[heatfilter]

try jerking off that fast LOL... good vid man.

[deuketc]

@heatfilter :) haha.. Thanks

[imatube2]

How long did this take you?

[deuketc]

@imatube2 The sanding took just over an hour

[lukenfoci]

Nobody noticed, but there is 5C difference in system temperature - after lapping system temperature is 5C lower what influences results ratjer a lot.

[Vihsadas]

Holy fack. Nice temps jesus. I'm totally unsatisfied with my Corsair H50. I'm going to lap the shite out of my i7 and H50. 0_o

[deuketc]

@Vihsadas Hi, thanks.. Ive tried a few things to help with temps. I first replaced the stock cooler with a zalman, then a thermalright true 120, then the water cooling setup,, all helped but lapping was really effective. Good Luck!

[Vihsadas]

@deuketc Thanks! I hope it works. I'm really praying that most of my temp problems are a convexity issue with the IHS. We'll see I guess.

[DiGiTaLdAzEDM]

@deuketc The temp difference is almost hard to believe. Anyways, I am in the process of a rebuild--I am ordering thermal compound on Monday. Found some stuff new to me--am considering Arctic Silver 5, Arctic Cooling MX3, or maybe Indigo Xtreme. Any thoughts? The Indigo requires CPU to be run for 5-10 mins. at 90-100 C (by disabling CPU cooler fan) to melt the compound. Sounds a bit dicey.

[deuketc]

@DiGiTaLdAzEDM HI, this was the first time i tried this, and i didn't expect it to help that much..been running the q6600 for a while now, tried a few different coolers zalman, thermalright,, but nothing helped as much.. its something you really got to try for yourself. for the thermal compound i had been using artic silver5 but recently ive changed to mx3 so far i think it spreads easier and its also non conductive, just used it on a 5870.. Good Luck!

[PCGamer333]

yeah 20 degrees is to much i think is coz the thermal paste

the old one was a poor apply

after the lapping ++ new apply

well it was a nice drop of temperatures

but mostly cox the thermal and the lapping

has not technique but..ill give a 3 out of an scale of 5

due poor technique..

[e13373]

It is NOT possible in any way to shave 20 degrees of the temperature just by cpu lapping!

[deuketc]

@e13373 on average the drop was about 12 degrees, core temp showed a 20 drop but the IHS wasn't very flat to begin with.

[gippula]

i have q6600 idle 46C and load 65C i use noctua uh n12p cooler. 9x400 1.28 vcore.

if you guys have any suggestion how to get the temps lower, please send me some tips. THANKS!!! cpu is not lapped and im not planning to.

[deuketc]

@gippula Hi. are you using 2 fans with your cooler for push pull config? what thermal compound are you using? Im using artic silver 5 which can help temps. good case airflow can also help. temps dont sound too bad though.. i try to stay under 70c full load when aircooling

[Ripzta13B]

@gippula

Try changing the Distance to TJ Max setting in RealTemp according to your CPU model.

deuketc has set his to 90 on all 4 cores. This will show lower/proper temps accordingly.

[CoreyPL]

Nice temps after just lapping CPU. When you showed lapping result after 600 grid it was clear how your heatsink was far away from flat. I have the same problem with mine heatsink. Temps between cores on my Q9550 can differ up to 15 deg C, so no perfect heatsink too. I'm planning to lap my CPU and (cooler if needed) today, so I hope it will have some good temps - mainly to run my fan at lowest settings, because I like the silence :)

[Saipyyyy]

LOL i have with my Q6700 @ 3.2 Ghz with the Coolermaster GeminII with 2 Xigmatek´s idl core 1-4 between 15-22°C and on last never higher then 38°C the cores^^ lol^^

[nLevel20]

good job!

[openingfuel]

wow, i might need to give this a try
