The 3Racing Extended Motor Heat Sink with Fan is a compact cooling upgrade for 540 can motors. Finished in black with a fan-shaped profile, it helps move heat away from the motor casing so the motor maintains consistent performance under sustained runs and high loads.
The extended wraparound body increases the surface area in contact with the motor can, while the integrated fan drives extra airflow across fins. This combination lowers operating temperatures and reduces the chance of thermal cutbacks during competitive use.
Built to fit common 540 motors, this heat sink installs quickly and requires minimal adjustment. Its straightforward mounting makes it a useful upgrade for anyone looking to reduce maintenance and keep more time on the track.
