if you have a sealed box for the amps, having a fan pull air in wont work.
where would all the "new" air come from? since the box is already filled with air, all the fan is going to do is create a vacumm and suck the air out. theres no inlet for "new" air to come in.
Will,
I'm sorry, I made the obvious (to me) assumption that you would provide an inlet for the amprack.....you brought up the ideas of computer cases, so lets run with it....
So you go to mwave or newegg and buy a Antec 800 series case. What does it have....only two exhaust fans. Those inlet areas have filters on them for the dust. Now a computer case is a different monster because of all of the obstructions (AGP, PCI cards and the processor) all of these things impede flow....also a computer case is far from sealed.
So, you can still run just exhaust fans and be ok....you don't have to run inlet fans. Because of the obstructions, it's nice to run a side panel fan or front case fan....why, because of stagnation...you won't have much stagnant air in an amp rack.
