I must disagree by saying that 90deg is very high. very high indeed. I can't see those things lasting very long at those temps, not to mention perform optimally. Just as a little idea, my 8800gts never got pass 72deg under full load, overclocked to the tee.Now if you are adventurous enough, you can remove the heatsink off the card, wipe away the thermal compound on the gpu and apply some fresh AS5. If you're not up for that, use riva tuner or your tweaking tool of choice and up the fan speed as desired. This will make a big difference w/o changing anything else.
