The ATI Radeon HD 5700 GPU that I have is a hotbox. At idle it sits at 65-70c and during gaming it sits at 85-90c, I used to have it at 40-50c under any load when it wasn't in a case. Does anyone know what I could do to get it back down to at least 50c? I even used a secondary fan to blow air directly to the back of the card and it still won't go below 60.
