3Racing 540 Motor Cooling Heat Sink Fan 3RAC-MHS007/BU - Blue Edition  [3RAC-MHS007/BU]

Smart thermal control for 540 can motors

The 3Racing Extended Motor Heat Sink with Fan brings improved thermal management to 540 can motors. It is aimed at hobbyists who want steady temperatures during longer practice runs or club racing.

Aluminium body with continuous airflow

The heat sink's aluminium construction provides high thermal conductivity while the integrated fan supplies continuous airflow across the motor shell. This combination helps limit temperature spikes during heavy throttle use.

Easy mounting across platforms

Designed to match typical 540 motor dimensions, the unit mounts cleanly to many chassis types. Its universal-style fit makes it suitable for both street and rougher off-road conditions where extra cooling is useful.
