optimal fan location?

[Conroy9]

My case has places for a fan in the top, upper rear (below the power supply), lower front, and another one in the front directly above that.

If using only two fans, is there a best theoretical place to put them?
If the two fans push different amounts of airflow, where should the more effective fan be placed?

If using only one fan, Is there a best theoretical place to put it?


I'll do some experiments and post my results too if there is interest...

Too much exhaust can cause air and dust to be sucked through the optical drives. Too much intake can cause stress on the fans, and not be efficient. It's good to have a balance of air flow. Generally you want to suck air in through the bottom of the case and have good flow to the video card. Then the output air should be in the top back of the case.
