How often should you re-do thermal paste?

post #1 of 7
Thread Starter 
I've had a 5850 for about a year and a half now and it's been in an out of various pc's, it's overclocked to 775/1125 (none-reference so i can't change the voltage) and i'm just wondering if there's any need to re-apply thermal paste. I've seen it go hard on old processors and it's just a question really.

Also, what gives more fps gains, core overclock or memory? I'm considering trying to push it a little further

Core overclock for those fps gains, and If your card is out of warranty then it's time to do it. smile.gif

^ coreclock, I tend to re-do thermal paste every year just because I'm a nut about these things. Same with cleaning my case and filters. thats might just be me tho,

for GPU, i try to replace it every 6 months because they tend to run hotter than CPUs

and as Conner said, core overclock to gain fps.

when you do replace the TIM, make sure you clean the original thoroughly. also try not to mess up the thermal pads or you're going to have to buy new ones.

use the X then + method when applying (draw an X then a + on the gpu die) I also suggest using non conductive TIM like OCZ Freeze if it's your first time.

using too much can cause temps to rise to try to use a bare minimum.

i think that's all and pm me if you need anymore help! biggrin.gif

As much as I love the 5850's the non-reference cards blew, especially the XFX models. They can't overclock as well as their reference brethren.

it was the cheapest one at the time and i didn't do my research properly with regard to the reference models, i m considering getting another one because it's the cheapest way for me to get great performance, however i don't think my psu will cut it
