        It depends, I personally turn my case into a wind tunnel. I have a fan
sucking air in, in the front of the case, blowing directly on the chipset
and CPU, a fan on the CPU blowing downwards helping the 1st fan, and the
power supply fan that blows out of the case. In effect I have a wind tunnel
that covers most of the board and drives. I suggest you do the same, don't
have two fans fighting each other creating higher pressures in some areas
and lower pressures in others, keep the airflow steady and linear. Hope this
helps. TTYL
