Not sure if this is a gpu or psu issue, but my comp goes black during high load games. I hear the fans go real loud (not sure which ones) and the monitor go black. This only happens on hot days so I'm pretty sure it's overheating. Some games, the temp will hit 85-90c I think that's when it goes black. I'm thinking about getting a fan or something but not sure which is a good gpu fan for Galaxy gtx 580. Anyone have any ideas?
