3RACING 3RAC-MHS003/PU Race-Intent Fan Heat Sink for 540 Motors  [3RAC-MHS003/PU]

Targeted Cooling for Competitive 540 Motors

For track-focused setups, maintaining motor temperature is a key part of consistent lap times. The 3RACING 3RAC-MHS003/PU fan-shaped heat sink enhances convective airflow over the 540 can to help manage temperature under race conditions. The fan profile moves air along the motor body where heat buildup is most likely to occur.

Engineering and Fitment

Finished in purple, the sink offers a visual identifier for tuned cars while fitting the common 540 can diameter used in many racing classes. Its clip-on design simplifies installation and allows quick swaps between practice and race motors.

Setup and Orientation

Mount the heat sink with the fins aligned to channel airflow from front to rear relative to the vehicle direction. Proper orientation helps maintain motor efficiency during extended or repeated runs and supports repeatable performance between heats.
