I have an Antec P183 and us a Corsair H80 in a push/pull setup as intake. One exhaust fan up top and an intake on the front panel. All the fans are on a fan controller and rotate at 1000RPM for max quiet. I have less exhaust fans running at lower speeds and it is alright in my PC...You'll be good in that setup. Don't forget that the air will naturally ventilate thru holes/cracks even if the exhaust fans can't move as much air as your intake fans.
