Thermal Paste for CPU and GPU

post #1 of 7
Thread Starter 
What is a good thermal paste to use on my CPU and GPU. I have been searching for hours. I was just going to grab some AS5, or is MX-4 better?

Indigo Extreme seems a little too much hassle.

I looked at ICD too, but reviews said it was thick, sticky and a pain to deal with.

Not looking to break the bank here on TIM either. Personal favorites are greatly appreciated! thumb.gif

You don't want AS5 for a GPU; you need something non-electrically-conductive (additionally, AS5 is outdated and no longer remotely high-end). MX-4 is non-electrically-conductive and one of the better TIMs on the market. If you want one TIM that you can use on both, MX-4 will fit the bill just fine.

EDIT: Missed the word "don't" in the first sentence and cleaned up wording

I recommend ICD as it works pretty well. But your right, it is a little thick. Nothing hot water wont fix. Most if not all will be within a few degress of each other. If that does not bother you, get whats cheapest.

after doing some research, went with MX-2 over MX-4, just based on various temp tests and tim review. Prob only a 1-2*C diff, but thought id try

Why does thermal paste need to be non-conductive? Unless you have one of the ASUS direct CU graphics cards there is still an IHS on the GPU.

Unless you are using paste on the VRMs and memory...which I would not recommend. There is often too large of a gap for paste to work well; especially with the VRMs. You typically should use a thermal pad.

I still have tubes of AS5 around that I use on things like stock coolers and junk like that...in my own rigs I only use MX-4 these days...though I don't really know if there is that much difference between it and AS5...maybe a couple of degrees under load.

ICD will scratch the shizznit out of your CPU surface, my QX9650 had no batch number on surface when i sold it on redface.gif
Thats said its great stuff, pop the syringe in cup of hot water for 5 mins or so first before applying.

Don't use IC Diamond on your GPU. You can scratch the die.
