Hmm there needs to be a sticky about temperatures. Alex is right. GPU's can take much higher temperatures than CPUs. While someone could be rightfully nervous about a CPU load temp of 60C, a GPU idle
temp of 60C is just fine. GPUs can withstand temperatures of over 100C. For instance, the "core slowdown temperature threshold" of my 6800 vanilla is 127C, so the core will run at full speed until it reaches that point! Then
it will slow down, and then
it will shut itself off, maybe at 140 or 150C?
Basically, one doesn't really have to worry about GPU temps at all. The only reasons to consider aftermarket cooling are overclocking and noise.
