Seems it would help with cooling the amps, unless it causes hum or is blowing a ton of dust into the amp vents. No doubt background noise for you seems not to be a issue Heat and dust are the amps enemy, same issue really, load the amp with a 2 year dust blanket inside (comming from the AC.) and it will retain heat.
If the tops come easy there are top vents that may fill with dust. Unplug after a month, no huge dust, go 3 months to see if it's a issue. IF THERE IS A ISSUE, TOP OFF, UNPLUG, LET IT COOL DOWN AND BLOW IT OUT WITH CANNED AIR. CANED AIR IS FREEZING, IF BLOWN INTO A HOT AMP THE COLD HITTING THE HOT CIRCUITS COULD BREAK A CONNECTION
SORRY ABOUT THE CAPS, THEY GOT STUCK AT THE END AND DID NOT WANT TO REBOOT
