Really? Must have missed the HD2900XT's, then. Also anything in the 8800 series from nVidia runs particularly hot. I had an 8800GTS 320, and it would regularly hit 70C idling, loaded around 95. Even my Vapor-X HD4870 (with an awesome cooler) had to have the fan speed forced to 60% else it would sit around 70 idle, and the VRMs at load, no matter what the fan setting, would always hit around 110C. Mind you, this was also in a case with ridiculously good cooling.
But GPUs are meant to be able to withstand extreme heat (100C is fine for most of them, unlike CPUs that usually don't like going over 85).
