I've installed ASUS DC2T-3GD5 for mining and its reaches over 90 C in 7 minutes and the heat increases gradually. I have two cards but I didn't use the second one yet due to this heat problem. Do I something wrong? I don't know its about the room temparature. (it's 18 C) I used a 7950 in january and it was always around 75 C. I have a side and front intake fan, and exhaust at the back.
