**Cooler for TPA 3116 Audio Amplifier 2x50 W**
The Amplifier gets pretty warm when used under a high load.
For better cooling I added a 40x40 mm Cooling Fan with 24V (Two wire).
The Fan is fastened to the print with M3x16 Screws with matching nuts.
The wires are soldered to the 24V Input Jack (it should work with variying input voltage but 24VDC is recommended)
For a better fit do not tighten the screws fully before each is threaded in
