I've never seen any specs or data on how long you can drive a CIM at different power levels before it overheats and is damaged.

The CIM is a sealed motor; no ventilation. My understanding is that it was designed for intermittent use. It has sufficient mass to absorb a lot of heat for short periods of operation (like a 2-minute FRC match).

An external fan might help somewhat, but the real question is how hard are you going to be driving the motors.
