I have a 9800 gx2 and noticed that evga precision registers anywhere from 78-80C while idling (balanced performance and aero turned off to make sure that wasn't doing it) and gets up around 90C under load. when I boot xp, it only idles 71-75C. The fan is working properly and set to auto. however, everest ultimate shows the temps to be 71-73C idling while precision gives me the above temps. But regardless, both are hotter than when running XP. Though I dunno which app to trust.
