The 3Racing Extended Motor Heat Sink with Fan is a practical accessory for 540 motors, offering focused cooling in a compact package. Its black fan-style design assists in pulling heat from the motor shell to maintain more consistent performance during long runs.
The extended construction increases the radiator area that touches the motor can while the integrated fan enhances airflow through the fins. Together these features improve heat rejection when the motor is under sustained load.
This heat sink fits most standard 540 motor cans and installs easily, making it a convenient upgrade for racers who want a simple route to better thermal control.
