Thermal Paste on GPU

Hi everyone :).

I recently applied new thermal paste to my GPU and CPU, but I have been experiencing some problems lately. My CPU seems to run fine; however, my GPU keeps overheating. Before, I was able to play Diablo 3 without issue, but now my GPU's temperature skyrockets and the fan spins at max speed whenever I play. I think this is because I couldn't wipe off some of the old thermal paste on the GPU, but I'm not really sure. There is still grime on about a third of the GPU.

Does the old thermal paste on my GPU really damage my computer's performance this badly, or is there some other issue that I should look at?

    sir you are wrongly mistaken .
    putting thermal paste on gpu is totally heardof
    as for your problem you probably did one of the following-
    1)did not spread the paste evenly
    2) did not remove old paste before applying new paste
    3)did not place or fix the gpu fan in the correct position
    hope this helps
    cheers!

    Yup thats exactly whats wrong, you just can't reuse old thermal paste it just doesn't work, it acts more like an insulator then a conductor.
  4. i have clean many gpu i advise u to grab a artic silver 5 and a brush
    1 remove all dust on it
    2 u can also use a brush on gpu to clean old thermal paste
    3 apply the new thermal paste spread over th gpu make sure it paste cover all surface gpu processor
    4 clean heatsink and screw back to gpu
    u will fine
  5. for the thermal paste, id suggest getting arctic cooling mx-4 as it is better than silver 5 and does not require curing to get maximum performance.

    sometimes, gpus come with special thermal pastes and that regular stuff will just make it worse
