3Racing 3RAC-MHS007/PU Racing Spec Extended 540 Heat Sink with Fan  [3RAC-MHS007/PU]

Track-Focused Cooling for 540 Motors

The 3Racing extended heat sink with fan is developed for 540 motors to provide consistent thermal control during high demand runs. The extended fin area combined with an integrated fan increases convective cooling, helping to preserve motor output under race conditions.

Performance-Oriented Construction

Designed with a focus on airflow and contact area, the 3Racing unit clamps closely to the motor can to maximise heat transfer. The active fan forces air through the fin pack to reduce thermal stress, which assists in maintaining consistent RPM and torque across repeats of full-throttle runs.

Tuning and Installation Notes

As a practical tuning upgrade, this heat sink is straightforward to fit to standard 540 can motors and integrates with existing power and control wiring for the fan. It is a compact, value-conscious part for racers wanting better temperature management without extensive chassis changes.
