I think we are all agreed, its a good beginner motor to get into the hobby to see what these things can do, but its not a long term solution.

one thing to remember about a motor is that the heat is generated in the interior and works its way outward (thermal dynamics) and when you blow cooler air onto the motor the cooler temp will not go beyond the edge of the hotter temp, so when you use a fan all you are doing is cooling the case and doing nothing for the rotor and magnets (the important parts of an electric motor)
