Yes,

Fans help out on other motors too. Try running a pair of Fisher Price motors at high load and run them intermittently in forward and reverse. They don't like that and you will see how smoking hot they get. Attach a pair of small fans to direct continuous air flow over the motor cooling slots and casing and you will see a tremendous improvement of the power output over a time frame.
