Tamiya M04M Aluminium Motor Heatsink with Cooling Fan M04M-07/LB by 3Racing  [M04M-07/LB]

Fan-cooled aluminium heatsink for M04M

This aluminium motor heatsink with an integrated cooling fan is made for fitting to Tamiya M04M motor endbells and helps stabilise operating temperatures during extended runs or setup sessions on the track.

The part increases surface area and forces airflow over the motor can to reduce temperature rise under load. Improved thermal control can lessen timing drift and power loss from heat, helping you keep lap times consistent while you tune gearing, timing, or ESC settings.

Fitting is straightforward for this accessory class: secure to the motor end using the endbell screws or available screw points, then route power to the small fan according to your wiring plan. Always check clearance against the spur gear, pinion, and nearby suspension parts before final installation to prevent rubbing or interference.

Bear in mind the heatsink adds a small amount of mass and a low-profile height above the motor. Use it as part of a cooling and tuning strategy rather than a substitute for correct motor choice, ESC setup, or overall chassis airflow management.
