I have an HSI x1950 pro PCIe that appears to be overly sensitive to heat. After a couple of hours of use, I get all sorts of graphical artifacts in WoW. Resetting the video card by changing some of the graphical settings will usually clear up the problem, but only for a short while. I checked the temp and fan using ATI Tool and it runs at about 45C and 40% at idle, and goes up to 80C and 70% in WoW. From what I have read, these temps are not unusual for this card. When I duct 5C air in from outside (there's a window next to my comp) into the case input fans I can get the temp during WoW down to 60C and then the problem disappears. I have cleaned the card of dust and physically inspected it. It looks like the GPU and memory chips are all in contact with heat sink (although the memory chips are separated from the HS by some kind of spongy pads that look more like insulators than heat conductors to me, but whatever). If this card is causing problems at normal running temps, I'm not sure what I can do. Even if I got a 3rd party HS/fan and ran it at 100%, I doubt I would be able to get the temp down to 60C using room temp air. Are there any other things I could do to salvage this card? Thanks.
