Hi im using precision xoc with a gtx 660 and when im am playing a game sometimes the fan goes down it does not stop but goes down low enough that the card starts to heat up and i get a black screen and i can still hear the audio but no picture. I have to close the game down adjust the fan slider back up then the fan speeds back up then i can play again. Any suggestions? I am running the latest drivers on my card and on precision xoc. Thanks for any help
