Do GPUs use the vents in the back of the cards (by all the video output ports) as air intakes or air exhausts? I am running an open air case with a box fan for cooling. I want to direct my airflow correctly to get maximum cooling and not restrict the way air is supposed to be flowing for cooling the card.

Back is exhaust. If you have your case open, point the fan directly at the cards as though it was the side panel with a fan on it. Cool air onto the card, stock fan blows it down over the card to cook, and then goes out the back.

Thanks. I have an open air case that i built. I will put the fan on the other side of the cards so i am not blowing air into an exhaust vent.
