    The power amp side was toast, i ordered a replacement board. When I hooked up X3 it arced on PS.. Now X5 arcs as well. Looks like the 4700uf 100v caps tie directly to that..could one be bad? Could my new board be damaged? The fan don't blow hard when the 6wire plug is plugged into power amp board, unhook it and the fan blows great..

    X3 probably 'arced' because you did not drain the power supply capacitors before you plugged in X3.

    The fan has a feedback that will make it run fast when the amp gets warm.

          Transistor? Or triac.
