Ok, I think I get it now. The heat generated from within the motor is the current running through the winds to create the magnetic field. So a 10XL on 6S not only runs the speed controller cooler, but the motor runs cooler as well. So an 8XL geared up really wont give less heat than a 7xl geared down if you are running the same voltage because the current will be approximately the same.
