I will be getting a second Matrix and I'm worried about the temps of the top card. I really don't want to go to water cooling. My case is the Corsair 650d and board is the Asus Hero. I was thinking moving a drive bay to the middle of the base on the tower and mounting a fan directly on top of it. So the fan would be close to the rear of both cards. The case doesn't have side mounting fans. Would that setup keep the top one cool and send all the heat to the vent at the back of the card?
