Might be a sign of running higher line voltage than it was designed for.
Or that the design didn't quite include enough heat sink area. The fan
is a good help. You might try lowering the line voltage with a variac or
bucking transformer to see if it can still regulate for transmitter CW
key down. You can reduce the power wasted in the power supply that way.
