i dont get that...
if you have a sealed box for the amps, having a fan push air out 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.
if you have a sealed box, with 1 fan on one end pulling air in, and another on the other end pulling air out...that would be a better config. since the heated air will rise from the amp, and be sucked out by a fan. and at the same time more air will come in. the air coming in would be naturally cooler than the air on top of the amps.
im just taking what i know from putting fans in my computer case.
you want the same amount of air going in, and going out. so look for fans that have a the same CFM rating.
i bet you can even use computer fans, good quiet ones go for no more than $20 each.
