The 3Racing Motor Heat Sink with Fan 3RAC-MHS004/LB offers a straightforward way to reduce operating temperature on 540 motors. The light blue aluminium body helps move heat away from the motor can, keeping performance consistent in longer sessions.
Keeping temperatures down reduces wear and helps maintain power during repeated runs. The fan actively moves air across the heat sink fins to lower temperatures and reduce the chance of thermal shutdown or damage.
Designed around standard 540 mounting patterns, this unit fits securely and provides good contact with the motor can for efficient heat transfer. It is a simple upgrade for racers and hobbyists alike.
