Engineered Cooling for 540 Motors

The 3Racing Motor Heat Sink with Fan 3RAC-MHS004/LB is intended for hobbyists focused on dependable thermal control in 540 motor applications. The light blue aluminium housing offers a durable contact surface and facilitates convective cooling when the fan is active.

Thermal Management and Racing Use

Consistent motor temperature reduces performance variance during repeated runs. The integrated fan directs airflow through the heat sink fins to enhance convective heat transfer, supporting tighter temperature control for competitive settings.

Mounting Considerations

Designed around standard 540 can geometry for straightforward installation, the unit provides reliable mechanical contact for heat conduction. Verify shaft clearance and can diameter to ensure optimal fit and thermal coupling.

What should I check before fitting?

Confirm the motor can diameter, shaft clearance and available space around the motor to ensure the heat sink mounts without interfering with other components.

How is the fan integrated into race wiring?

The fan is typically powered from an ESC or receiver auxiliary output. Use appropriate connectors and secure routing to prevent interference with moving parts.

What maintenance is recommended?

Inspect the fan for free rotation, keep fin surfaces free of debris, and periodically verify mounting screw torque to maintain consistent thermal performance.
