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

Aluminium motor cooler for M04M applications

This low-profile aluminium heatsink with an integrated fan is intended to mount on the motor endbell of Tamiya M04M motors to help manage temperatures during longer practice or track sessions.

By adding extra dissipation area and directing airflow over the motor can, the heatsink slows thermal buildup under load. That thermal moderation can help prevent timing shifts and power roll-off caused by high motor temps, giving more repeatable performance while experimenting with gearing and ESC settings.

Installation follows typical endbell-mounted accessory practice: secure to the motor end with the endbell screws or designated screw points, and wire the fan to a suitable low-voltage source. Verify clearance around spur gear, pinion and suspension parts before final tightening to avoid contact.

Remember the unit introduces a bit of extra mass and a modest height above the motor. Treat it as a tuning aid to stabilise running rather than a complete fix for incorrect motor selection or poor chassis ventilation.
