Okay well i have a Leadtek Winfast A400 GT (Geforce 6800 GT) and the card has been overheating pretty badly lately. I checked to see what the problem was and it seems the fan on the video card has slowed down a lot. Sometimes it even stops. So I was wondering if this could be a problem from the power supply or anything? Or if i should go get a new fan for my video card. And if i should get a new fan for my video card, could someone direct me to a fan that will be compatible with my card. Thanks for the help.
