| The "alert threshold" is default of 127C. I'd say 90C is acceptable. Without forcing your fan to a certain speed, the choices the BIOS of the card makes on setting the speed is really... slow. I accidentally went to sleep with a game running and without forcing the fan speed. When I woke up the following morning (probably about 8 hours later), the fan speed was at 73% and the GPU was at 93C. The game was still running perfectly, no slowdown or artifacting. If I force the fan speed to 100%, the card will idle around 56C and under load at about 68C. My card has a ball-bearing fan so I'm not really worried about the fan going bad. By the time the fan goes bad, I'll already have a 8800GT or something better to replace it with.
