How to Apply Thermal Paste / Replace TIM on 480GTX ??

post #1 of 8
Thread Starter 
After months of use since now its summer here, few days ago I applied some AS5 thermal paste to one 480GTX and the temps raised about 10C!! I used a bit too much paste I guess with small lines on each heat pipes and a big bb size drop on the gpu(as suggested in one evga forum)..

So, Whats the correct method to replace the TIM on the 480GX? A Cross (X) a BB or Pea, or Lines?

It has 5 heat pipes directly touching the GPU die. I have some more AS5 left so wanting to have a second go if you could help or have some instructions.

sorry for another annoying little question.

If I remember correctly a big pea works well.

There's a plethora of ways to go about with applying TIM.

I usually just place a decent sized pea, not massive but at the same time not too small.

Then I take a credit card to even it out all around the GPU die or CPU.

The pea size amount is for a cpu sized chip. The size of the gpu is smaller so pea size is too much.

Rice size works better

but the 480gtx is not like cpu coolers, it has a direct touch heat pipe with groves / gaps in middle. and the GPU is on these cards are at least as big as the CPU, if not slightly bigger..

anyone that have done it recently to their 480 GTX with decent results? my stock idle was 41C, but now its 51C - 55C after the TIM replacement !!

Have you tried applying the paste to the heatsink as well as the die? I'd recommend doing that, especially since it has heatpipes touching it - make sure to get those areas in between them.

hi, yes i have put 5 small lines in the heatsink/ HDT / 5 heatpipes, and then a big bb in the gpu, didnt work and raised my temps 10*C any solutions? now i'm beginning to think i should have left the stock tim alone.

edit: you have the same cards as me, how did you apply them?

i reapplied using a mid sized bb on the gpu and two lines on the 2nd and 4th heat pipe, not much of an improvement, same crappy temps.

thanks for all your help, wish I could rep you all but i dont have any myself
