3Racing 3RAC-MHS007/GO Gold Extended Motor Heat Sink with Cooling Fan - 540 Fit  [3RAC-MHS007/GO]

Keep 540 Motors Cooler with a Gold Fan Cooled Heat Sink

If you want more consistent motor temps during long sessions, the 3Racing Gold Extended Motor Heat Sink with Fan is made for 540 motors and built to improve cooling efficiency. It helps maintain operating temperature and reduces thermal buildup under sustained load.

Better Heat Dissipation for Reliable Runs

The integrated fan boosts airflow across the fin array to accelerate heat transfer away from the motor, lowering the chance of thermal cutoff or power loss. The gold finish is hardwearing and suited to hard use while adding a refined look to your build.

Easy Fitment and Compatibility

Designed to work with a broad range of 540 can motors, the unit installs quickly and secures tightly for good thermal contact. Precision fit reduces wobble and lets you focus on tuning rather than troubleshooting overheating issues.
