However I would like to point out that controlling the fan is a must for me at these speeds. For some reason my card simply refuses to up the fan speed on its own. Might be only mine might be everyones I don't know. Otherwise these speeds are highly unstable and my system simply shuts down. I don't know if I can go any higher with it but with how hot it gets I don't want to try it. I ran HL2 , CS:S , COD4 , Crysis , and bioshock all at these settings. 100% stable but again only if I turned up the fan.
