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

Low-profile heatsink and fan for M04M motors

This aluminium motor heatsink paired with a small cooling fan fits onto the motor endbell of Tamiya M04M units to aid thermal control during extended driving or tuning runs.

The component increases the effective cooling area and channels airflow over the motor can so temperature rise is reduced under sustained load. That helps limit timing drift and power sag from heat, supporting steadier lap times while you refine gear ratios and ESC parameters.

Fitment is standard for this class of accessory: attach to the motor end using the available screw points or the endbell screws, then route and connect the fan power according to your system. Always check for clearance against the spur, pinion and surrounding suspension items before final assembly to avoid interference.

Note that the heatsink adds a minor amount of mass and a low profile above the motor. Use it as part of a balanced approach to setup and cooling rather than relying on it alone to cure overheating or incorrect component choices.
