Technical Cooling Component for 540 Motor Builds

Engineered for race setups, the 3Racing 3RAC-MHS005/GO heat sink with fan increases thermal surface area on 540 motors to lower operating temperatures during repeated high-load runs. The fin geometry directs airflow over critical motor surfaces, reducing thermal throttling risks common in prolonged sessions.

Race-Focused Durability and Fit

Constructed with a wear-resistant gold finish, this unit is intended for frequent pit-side handling and quick fitment. Its form factor matches standard 540 mounts and supports easy integration into tuned packages where maintaining motor efficiency under stress is essential.

What clearance checks are required before fitting?

Confirm motor length, endbell protrusion and chassis clearance. Ensure the sink seats flat on the motor cylinder for optimal thermal contact.

Is additional thermal interface material recommended?

A thin, even layer of thermal compound will improve heat transfer between the motor can and the sink, especially for competitive applications.

How does this component affect drivetrain tuning?

By lowering motor temperature, the heat sink can help preserve consistent power delivery under sustained loads, allowing tuning decisions to focus on gearing and suspension rather than thermal mitigation.
