Ive got 2x radeon 6950 (2gb) running in crossfire mode...what is a reasonable temperature to operate while gaming? right now im using a case thats too small to house everything (first build newbie mistake) so ive got the case open and a house fan blowing on everything...with the house fan and 75-80degree Farenheit ambient temp...my pcie1 slot reached low 60 degrees centigrade...how does that rate?
