Reapplying paste on gpu

post #1 of 10
Thread Starter 
I know for cpus I just do the pea method and let the heatsink spread the paste out itself since most of the temp of the cpu is at the center anyways.

Do I do the same for applying thermal paste on gpu? do I let the paste spread itself or should i spread it?

I am using gelid gc extreme which is non-conductive and is relatively thin

Well it depends on the gpu.

My personal method is line for larger gpus like on my old 465, and rice grain method for my ati cards. I apply an amount that I don't feel is too much, then I bolt the cooler back on, start it up, then take it off again to see if it spread properly.

If it spread properly, great. If it needs a bit more, I add where it's needed.

Good luck!

I use the pea-dot (rather it's like a 1/3 rice grain drop) on my GTS450, and i spreaded the paste on my old 9400 GT (the die was way too small). It really depends on how big your chip is, and if it has an IHS or not (like on the big dogs like the GTX 480/580's)

I have a gtx 570, so then i should just let the heat sink do the spreading?

I'd do the center spot method and let the HS do the spreading, as long as you apply enough TIM to cover it all, but not too much that it overflows. Personally, i do not know if the chip itself has a IHS or the chip is bare, but as it's a high level card, i'd say it has an IHS.

Ive always used a line and spread it out paper thin with a razor blade.

Yea the chip is not bare on the 570

I do the pea method on GPU's, just use less for a smaller spot or even smaller for chips without an IHS.

The line method works and let the heatsink do the spreading.

I see no use using a line to apply the TIM on a GPU, since none is a dual core and all it has under the TIM is a squared chip. According to Artic Silver, the only reason to apply TIM in other ways than on a dot or spread out is if the cores under the IHS are in other form rather than a center square (like dual cores, which are placed in a rectangle, hence it makes sense to add it in a line)

Also, spreading out manually works as well, but meh, i'm too lazy to do so
