TRUE Black 120, High Temps w/ i7 920

You mine as well lap your CPU and your TRUE, it should eliminate this problem

Ohh.. so need to lap it ? zzzz

You have a great cooler with good fans, theres not much you can do except lap and pressure mod. What Vcore are you using? i7 920's can overclock pretty high on low Vcore and excessive amounts of Vcore will give you a lot higher temps. If you use your rig for gaming then you can disable HT which will drop temps considerably.

i7's also just run freaking HOT .

I am at home now, my computer is at my office i forgot what my vcore is.. i think around 1.3? if not 1.35. I checked OCCT and CPU-Z it uses 1.28 then when i start OCCT Test it drops to 1.25-.27. I actually use half of the Chill Factor 2 paste drop it in the middle of my core i7, then installed the true..

I am actually thinking of changing my top fan of my p80 to intake, since its exhausting cold air from the front fans..

Then again, TX-2 thermal paste would be better then Chill Factor 2?

Stores here don't sell Arctic 5-7 they sell Arctic Cooling MX2 & Tuniq TX-2

Use IC Diamond

I thought mine was rather flat, too. Several hours of lapping showed otherwise:

If the base is curved it will make much more than a few degrees difference. Also, the extra fan on the end may not appear useful but many users claim that higher static pressure will improve cooling efficiency for a TRUE, and doubling the fans will increase the static pressure.

Oh my, thank you just read your adventure with your TRUE 120 Black, i wanna do the same thing, but just afraid i would damage the TRUE..

You got 400 Grit, 600 Grit, 800 Grit, 1000 Grit and 1500 Grit sand papers?

Another thing whats the ideal way to use the Thermal paste? a big drop in the middle then install ? or 1 drop aswell on the TRUE ? then squish! or use a credit card swipin it ? lol

Quote:
I used grit sizes from 180 to 2000. I have 2500 and micron sizes available but those will not improve temperatures much if used and so I reserve them for removing oxidation.

To apply thermal paste, I typically but a rice grain-sized drop on the CPU and then use a plastic bag stretched on my finger to spread it around flat. A credit card or something similary can be used as well. You also want to make sure you apply even pressure to the CPU when putting on the heat sink - so tighten the bolts on opposite corners first (like you are supposed to do with a tire) to make sure that everything is even. If you take off your TRUE now I imagine you will see thermal paste only covering a portion of the CPU and heat sink due to the curved base and/or uneven pressure when attaching the heat sink.

Okay thanks! i am wondering how much temp improvements did you get after lapping, or you went straight to lapping ? hehe.. i wish i could buy those kits in my country.

I haven't tested it on a system yet, so I couldn't tell you. When I lapped my Tuniq Tower 120, I saw a mimimum 2 degrees C difference, but the Tuniq Tower 120 base was flat and the TRUE base is not, so I would expect to see double the improvment at minimum.

EasyPCKits will ship overseas. It says so on their front page, in fact ($12 flat fee for air mail). I suggest you follow the techniquies I have outlined in my build log if you are worred you will damage something. Just don't put pressure on the fins or the heat pipes and you'll be fine!

Il rather buy here locally for the sand papers, although i need to find a glass

Your temps are high but even for me with a 3.9 overclock my temps get up to 76 77 range, which is hot, but my Artic Silver 5 has not had time to set in since I changed to a thermalright Ultra-120.. Friday and installed it. I did not lap since I was nervous of not knowing what I was doing, but I am going to do it next time I get a new part and have to go in and take things apart. I would say the temps are somewhat normal, but with Arctic Silver 5 , I would never smooth it out with your finger it makes so many small air bubbles it is crazy and not good for heat the heat is trapped in the air. I like the Arctic Silver Website says is put a thin Line vertical ( with i7 depends on the way you have it, long way put AS5 horizontal) since core are aligned vertically when in the motherboard.

Watch this video and it shows come things on how the thermal paste spreads it helped me to use what AS5 says to do, but cross pattern also looks as good. here:


I hope it helps, it helped me. And only with the old CPU's you spread the thermal compound around with your finger, not with the new ones that have the IHS, but the old ones without it you have to spread the compound out. Here is Arctic silver's instructions to apply it, and it has a note on core i7 so READ ThAT http://www.arcticsilver.com/ins_rout...2intelas5.html

Also to really push the heat up on your CPU use Linx! Linx for me gets my temps up to 77 max within 15 minutes, sometimes 5 it will bring them within 2 to 4 degrees of max within the 1st 3 minutes I guarantee it. Prime95 takes sooo ling and it does not raise my temps up as much as Linx, 6 hours of Prime my max temps are 74 73 71 68, now after 1 hours of Linx my temps are 77 74 75 70, big difference in such small time. It also can make your system blue screen if it will so much faster than Prime, within the 1st 5 minutes if system is really unstable, and then it will take longer if system is just a little unstable. Now with you use Linx, make sure you press the ALL button so you can use the max amount of memory, which will stress your CPU as much as your system can take, if you do nto like all then use 300MB less than the max reading in Linx. Try it I bet you will like it so much more than Prime95.http://www.xtremesystems.org/forums/...d.php?t=201670 Hope you like
