So I've had this card for awhile and love it, but recently after re-installing Win XP pro I"ve noticed that while gaming the fan will speed up to 100% for a second, then drop back down to my preset of 60%. It then returns to 100% a second later, and repeats the process until I exit any game. I don't remember this happening in the past, and it's so annoying that I haven't played any of my games in quite some time. Anyone else ever run into this, or know what the problem may be? I'm running the 175.16 drivers, and have set the default fan speed to 60% with Riva Tuner.
