I too have also wondered about the heat sink and curious on whether it worked or not.
With a cpu, the heat sink covers the entire surface of the cpu with thermal paste in between.
When you look at the heat sink on a tomy bit, it only touches a portion of the motor, so I’m not sure how and if it really works in dissipating the heat from the motor.
Perhaps someone else know more on this…
Cheers,
Kevin
