quite true. Cooling fan needs own motor.

Subject: [Electric Boats] cooling an electric motor?
it seems that the cooling mechanism for electric motors usually consists of a shaft mounted fan of some sort... in one way this is obvious but then again at low rpms there isn't much cooling going on and this is too bad as electric motors have the advantage of delivering high torque at low rpm.... seems like an externally powered fan system that move air at sufficient velocity regardless of the the motor rpm would be much preferable....
