And while I'm thinking about it, wouldn't (in the abstract; I'm happily reassured WRT my actual build) a positive pressure setup have lower total cooling than a system with neutral pressure? (After thinking I decided that negative and positive pressures would cancel out, although that is pure intuition).

Or, to approach it from the other side, what would I have to do to need to get aggressive with cooling?

A huge case is a benefit in the non steady-state condition when you first start your game. If you run your benchmark during the first couple of minutes that the computer is turned on from a cold state, a large case will still be warming up, so you'll get a better e-peen number.jangove wrote:Why does case size make a difference? is the increase in air volume that big a deal?

If a larger case has say 2 fans on the front and 1 fan at the top rear for exhaust will the case still have positive pressure if the entire top of the case perforated (even though there are no fans mounted on top)? My first thought is that some of the warmer air inside the case would naturally rise out of the top of the case with no fans while the rest would be exhausted out of the rear fan.
