Accurate testing separates fact from subjective opinion - as each PC case cooling situation is different.

Heat does rise...when there are no fans controlling the air flow. In every case with a "top exhaust" and an air cooler on the CPU I get better system temps with that top fan as intake since it will feed ambient air directly to the CPU and motherboard. the air would have to be extremely hot to overpower even the slightest air flow from a fan...as in hot enough to likely melt the plastic fans. The rear exhaust is often in the same boat...use the front fans as the exhausts since there is nothing there that really needs to be kept cool. Hard drives actually work better if they are little warm...though I don't know about SSDs, but they don't get too hot anyway.

As to the OP...you just have to try it. I'd start with them all as intakes...look at temps while benching...then turn one into a exhaust...rinse and repeat.

i would like to know the best way to configure fans in the zalman z11 case, right now i have 8 fans set to intake and 1 exhaust. cooling isnt bad but i think it could be better. all fans in the case are cooler master jetflo 120's i have 2 in the front 2 in the top, 1 rear (exhaust),1 in the bottom and two as push pull on the cpu cooler.

Silverstone RV04 does not have an exhaust fan and is one of the best air cooling case. The inverted mb probably helps a lot in that situation. Heat will rise and will not affect cpu cooler at the bottom of the case.
