3Racing 3RAC-MHS008/BL Technical 540 Motor Fan Heat Sink  [3RAC-MHS008/BL]

Thermal control for 540 motors using 3Racing 3RAC-MHS008/BL

The 3Racing Extended Motor Heat Sink with Fan is a targeted cooling upgrade for 540 can motors used in tuned and race setups. The black fan-style sink enhances convective cooling at the motor can interface to help maintain steady operating temperatures during prolonged or high load runs.

Design focused on heat rejection and airflow

The extended wraparound construction increases conductive contact with the motor can to improve heat transfer. The integrated fan assists with forced airflow through the fin array, which supports lower steady state temperatures and reduced thermal throttling in racing conditions.

Fitment and installation for competitive builds

Engineered for compatibility with standard 540 motors, the unit is straightforward to mount and integrates with common motor setups. It provides a simple, effective thermal upgrade for racers looking to stabilise motor performance and reduce temperature related variability.
