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

Motor heatsink with fan for M04M

This is an RC-scale aluminium motor heatsink with an integrated cooling fan, produced by 3Racing for use on Tamiya M04M applications. The component is intended to sit on the motor endbell to help control operating temperature during sustained runs or tuning sessions on track.

The design role is straightforward: provide additional dissipation surface and forced-air flow over the motor can to slow temperature rise under load. That thermal control can reduce timing changes and power roll-off that come from higher motor temperatures, helping consistent lap times when you are tuning gearing, timing, or ESC settings.

Installation is typical for this accessory class: mount to the motor end using the motor's endbell screws or available screw points, then route power for the small cooling fan as required by your setup. Check clearance with adjacent parts such as spur gear, pinion, and suspension components before final fitting to avoid interference.

When selecting gearing or motor timing, plan for the heatsink to add slight mass and a low-profile height over the motor. Use it as a tuning aid rather than a cure-all: consistent cooling helps repeatable performance but does not replace correct motor selection, ESC programming, or airflow management in the chassis.
