3Racing 3RAC-MHS007/BL 540 Motor Cooling Fan Heat Sink High Finger Black  [3RAC-MHS007/BL]

Compact Cooling for 540 Class Motors

Pushing a 540 motor hard raises operating temperature quickly, so effective cooling matters. The 3Racing Extended Motor Heat Sink with Fan for 540 motors improves airflow right at the can, helping stabilise temperatures during long or aggressive sessions.

Extended Fin Array for Faster Heat Transfer

The heat sink uses a longer fin profile to increase exposed surface area and move heat away from the motor faster. The added fan boosts convection so hot spots are reduced and the motor can sustain higher output more consistently.

Built for Competitive 540 Setups

Hobbyists aiming for repeatable lap times will find this accessory useful for keeping motor performance steady. It suits setups where prolonged throttle or repeated runs push thermal limits and where consistent power delivery is important.

Fitting and Maintenance Notes

Fit the heat sink securely to the motor body and route the fan lead so it clears chassis parts. Periodically inspect the fan for grit or hair and clean the blades to avoid airflow loss. Proper care helps reduce thermal stress and prolong motor life.
