I have a full tower with a 92mm low speed enermax intake with a blow hole in the front and the same at the very top. I also put a low speed enermax in the middle back with a blow hole to exhaust the heat being sucked away from my Alpha.

newcompgeek: is your old heatsink mounted on the case or something? Having a fan within the case does not count as airflow :)

I've got 2 92mm Papsts at 7V in the front (I'm guessing about 50-60CFM intake there). 92mm Sanyo Denki in the side @7V (guessing about 20-30CFM intake). 92mm Sanyo Denki in the rear @12V exhaust (about 50-60 CFM exhaust). 92mm Nidec Beta SL up top @5-6V (about 15-20CFM exhaust). I've got another sanyo denki on the case door as well, but not used very often.

The case has perforations on the sides, I blocked some of the perforations to get a nice airflow that rises up from the bottom left to the top right with a goofd amount being force fed over the CPU and out the back.

Exiting out the top wouldn't work where I have my computers. W/o any backpressure whatsoever I'd probably be closer to 300CFM.

Inflow:
1: 120mm 102 CFM
1: 80mm 32 CFM in hole cut over Expansion cards ( in side, not back )

Outflow:

3: 80mm 32 CFM fans ( one in side of case between PSU's )
2 80 MM 32 CFM fans in the PWS's/ Replaced the STD ones. I run a 300 watt and a 200 watt )

Aprox Total CFM = 294.

I also have a 60MM delta screamer on the CPU heatsink, quad fans on my vid card ( all 50mm's ) and a Socket 7 Fan on my north and south bridge ( maybe 8 cfm ) Not counted in above :)

Total Fans = 14. Db's = alot :)

Intake:

2x80mm fans (one blowing over both HDs, but at an intake port)
@ approx 62 cfm

Exhaust:

2x80mm fans
@approx 60 cfm

So, I should get a total flow of about 60cf of fresh cool air blowing completely through the case every minute. In theory. Intake's are at the bottom front of the case, exhaust are at the mid/top rear. Oh...I also have the PSU fan, but I have no idea how much air that moves, and it's not really cooling the case, just the PSU.
