While waiting on my Audio cabinet to be built, I purchased A cooling fan system from http://www.coolerguys.com/840556090113.html.
My cabinet will be 70"W x 24'H x 24 "H. The two end compartments will hold my gear, while the middle section will house the center speaker and a lower drawer. A cooling fan system is my only option with space being so tight.
So for the benifit of those looking for a quite fan system ,I have already recieved and demoed the fan system, and can tell everyone is is very very quite . From 5 ft away I can not hear it at all. It has a themostat for each fan, comes on at 86 deg and shuts down at 81 deg .
