In tuning and race environments where repeatability matters, the 3Racing Extended Motor Heat Sink with Fan helps control motor temperature during successive runs. Its form factor targets heat dissipation at the motor can while providing airflow to reduce thermal drift between laps.
The extended fin array increases convective surface area and, combined with forced-air circulation, improves the rate of heat removal from the motor housing. This aids consistency in power delivery when track conditions demand repeated high-output bursts.
The component is aimed at racers and tuners who need reliable thermal management without major changes to motor or drivetrain layout. It is compatible with typical 540 can formats and supports sustained load scenarios encountered in club and regional competition.
Mount the heat sink to ensure unobstructed intake and exhaust paths. During setup sessions monitor motor behaviour after adding the cooling unit and keep the fan clear of debris to maintain airflow. Small adjustments to cooling can yield more consistent lap to lap performance.
