The problem is not how many fans you have in the box. The problem is how
much hot air you get out and how much cold air you get into the box.
Having
100 fans just recirculating the same hot air will do no good.
Make sure the fans are placed to make circulation and that air flow is
not
obstructed by those nice flat ide or scsi cables. If the case has two
fans
one should generally pull cold air in and the other should push the hot
air
out. Having both trying to push or both trying to pull will just make
the
air stand still.

Ahem... How do you manage to make a fan cool your CPU to below normal
room
temperature ? Either
1. you live in a fridge
2. the cpu fan-heatsink combo has a peltier device
3. your temperature sensor is whacked or,
4. the statement is BS
