i've used RT to set my GTX's fan to run at 75% all the time, but all of a sudden it keeps resetting back to like 35%. as far as i can tell, it does it when it is being stressed. like i opened ati tool, and when the cube started rotating, the fan slowed down.

just earlier, it did this, and i would go into RT and set it faster again and almost instantly, it slowed back down.

what could be causing this?
