Hey. I have a gpu that ran very hot (over 100 degrees celsius), so i bought some heat paste to try and make it run cooler. i know how to apply it to a cpu and i figured a gpu was the same from watching a youtube torturial.

When i opened my card a ati radeon hd 4800 I found that there was this chewing gum like substance that protected some of the circuits. that substance got a little ruined hen i pulled it apart.

the question is am i supposed to only apply it directly to the gpu in the same way i did to a cpu, or am i supposed to apply it to the little black plastic circuit covers that was covered by the chewing gum (which i asume is just another type of heat past)e aswell? as you can see in the pictures a little of the "chewing gum" came loose and got ruined

i Would really appreciate any answer. Im not very tech savy.

Well you apply the thermal paste as you would normally a CPU on the GPU core.
However the other pads (called thermal pads) act like thermal paste and on your card act as the contact between the memory chips and the vrm's to the cooler. Personally I would go buy some new thermal pads and remove the old ones. Just put the new ones in place of where the old ones used to be and you should be good ;)

-good luck

thanks for the answer. i reasembled the card and put it back in. the only thermal pad missing is half of the one on top. Do you think its a big deal? in other words are they essential or will this most likely be fine? again thanks.

As long as temps are fine you should be good. Download GPU-z

As long as all temps are good, such as vrm temp, memory temp and core temp. Under 80 degrees is fine when stressed.

-good luck
