So I am going to be water cooling my GPU, I have the 5000D Airflow, with an H150i elite cooler which is in the top, I plan to put the new radiator in the side but I am unsure about air flow. I would guess I need to do pull configurations on both the top and side radiator, but what about the front and back fans? I need something to pull air out, do I set the 3 front and 1 rear to exhaust?
