I purchased the Asus GeForce GTX 580 DirectCU II NVIDIA graphics card a little over two years ago. I gamed with it for several months before life got in the way and I had to stop gaming. Now I'm looking to start up again.. the fans aren't working on it. Is there a way I can specifically test them? I have run several tests of which I forget the names but the card heats up 90 without the fans cutting in.
