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

Keep Your 540 Motor Running Cooler

The 3Racing Extended Motor Heat Sink with Fan for 540 motors is built to help your motor run cooler under load. Finished in purple, this extended sink includes an inline fan to boost airflow and spread heat away from the motor, supporting consistent power delivery during extended practice sessions or race days.

Engineered for Effective Heat Transfer

Made from durable materials that resist wear, the 3Racing heat sink fits around standard 540 motors to increase surface area for cooling. The fan forces air across the fins to reduce thermal stress on bearings and windings, which in turn helps lengthen motor life and sustain peak performance.

Practical Upgrade for Racers and Hobbyists

Whether upgrading a club racer or prepping a backyard basher, this heat sink with fan is a straightforward way to manage heat. It is especially useful where repeated high RPM runs or long sessions push a motor into higher temperatures.
