Fan on Graphics card

I put mine to 90 percent manually, when I game. As long as you only do it when you game your fine.

In all honesty, I think you could run them at high speeds all the time and it wouldn't kill the fan that fast, but the time the fan would die becuase of that I think the card would be outdated and in need of an upgrade anyway.

alright thanks.. and btw, if i increase my core clock from 775 to 850, will it have a considerable impact on performance? last time i tried, i had some problems like driver not responding and stuff.. but i had the whole card overclocked. i dont want to overclock memory now though coz i have 1 gb ( not sure if the clock affects the memory with such unwanted VRAM )

What GPU do you have? If your driver is crashing a lot with it overclocked its just an unstable overclock.

Depending on the card however you may not see any real-world difference in the performance of the card.

Its a small innocent 5670

You're going to see a difference of about 2-3 FPS, doesn't seem worth it to me.

k, i tried increasing the core clock about 25 mhz.
