I'm using a Corsair Graphite series 600T. The only place I can place the radiator is at the top of the case. I can only put in one set of fans either pushing air into the case from the top or pulling air out of the top. Hot air naturally rises so i think i should have the fans pull air through the radiator but isn't a push configuration better than pull? If i push air through the radiator from the top how will this affect my airflow?
