Can my GPU be running very hot because it is clogged up with dust?

post #1 of 8
Thread Starter 
My GPU gets very hot (80C+) after just a few minutes of furmark stability test with the fan at 100%. It is 26C outside and maybe 30C in here and it is moderately clouded outside (must be 30+ when the sun is out). I was thinking on changing thermal paste but I dont have much left and I dont want to mix my homemade stuff with the OCZ Freeze. I live with 4 dogs and they loose alot of hair. could the heatsink be clogged?

It's a possibility, but not always the issue. Furmark pushes your gpu to the limit, so it's not likely that you'll see those temperatures in a game.

Clean the card of dust, check your temps, and you're set for more gaming/whatever it is you do with your pc.

GPU's can take 80c+ as long as its not like mid 90-95C then I would worry a bit.
Clean the dust out, itll run cooler and look it also.
With the fan at 100% the temp should average out after a while in the mid to high 80's(c).

my GPU gets to 75*C on furmark after 15 mins with 40% fan speed. 80*C is normal with furmark. My GPU is virtually new so has no dust.

yes dust will make your temps higher, esp if the heatsink is full of it

What worries me it that the temps keep climbing and when playing dragon age origins for 15 minutes my system freezes and I cant do nothing. the air coming out the back is very hot and when I touch the plastic that covers the heatsink it is burning hot.

another question I had was if I where o replace the TIM would I also have to replace the thermal pads over the memory chips or can I just leave them there?

Possibility. My GPU was running over 90 degrees when playing The Witcher and idled at about 70+. I cleaned the heat sink because it was quite dusty now it idles at 40-50 and never goes above 70 when playing games.
