Summer time, C4-8AMP1 gets horrible loud

During summer time the Control4 4 zone amps can be horrible loud, simply because the thermal management is not done/ done in a inappropriate way.

If you have a fan on hand, ideally 12×12 cm standard PC casing fan you can do a quick modification which will bring already a lot. This big fan will blow out the hot air trough the top ventilation holes.

Electrically it can be connected in parallel with the fanĀ  for power supply “PS FAN”. I used a Zalman ZF1225ASH, low noise fan

Mounting: Take screws, or just binders. Watch out that you don’t interfere with the big C’s on the board.
