Circulation Question

[RampantMjolnir]

Sorry if this has been asked a dozen times. I searched and didn't find what I needed.

My power supply is bottom mounted with the intake fan pointing upward towards the case interior. The fans I purchased for my case have arrows on them indicating both intake/exhaust, as well as direction.

The front fans are naturally set up as intakes (and directed towards the motherboard). The upper-rear and top fans are set up as exhausts.

What I am trying to decide is what to do with the side fan over the video card. Obviously it would be an intake, but should I direct the air upward toward the exhaust or downward toward the power supply intake?

Would be best with side intake and flip the power supply over if vented below it. If you keep it on carpet then just get a piece of wood or something to sit the case on.

Air intake should be Front and Bottom Intake and Rear and Top Exhaust. remember hot air rises naturally. Kenmitch is right on flipping you power supply so it pulls cool air from the bottom.
