Where should I send an RMA request to and can I at all??? Is this card considered OEM??? Is there any way to check to see if it is under warranty????

I've been using this card at stock and it is overheating. I was trying to figure out why i was crashing in SWG and i finally downclocked my card and the crashing problems were gone! I have 2 in and 2 out so ventilation isn't a problem.
