Q124 and Q125 run extremely hot. In time, they will cause the fiberglass board to become conductive from the heat.
The fan pulls air from the driver board side of the fan but does not produce much air flow over the board or the components. That's why I recommend replacing Q124 and Q125 (with MPSW42s) and installing them so that their body is as close to the fan blades as possible.

I will order up some MPSW42's. This amp came to me without a bottom cover, most of the leaded capacitors were bent over; close to shorting to other parts. The power supply and output fet were shorted along with issues on the driver card.
I have a hard time offering up any kind of warranty on this amp.
