Lately my card's fan has been having weird issues. While playing any game, doesn't matter which from what I've experienced, I'll occasionally hear a loud spike as if the fan has turned to 100% speed and my card will heat up over 100c, so far this has only happened twice, but that's two times too many. The card is an XFX 6870 and it's at stock speeds. I've tried the basics of wiping the drivers, reinstalling them etc. and I've even reformated (not due to the card, but the issue persisted even after the reformat). Has anyone heard of this happening before, and if so, know of a fix? Or will I have to RMA this card in for a replacement?
