When you want improved motor cooling without complex mods, the 3Racing 540 Motor Extended Heat Sink with Fan is a sensible addition. Designed to mate with standard 540 motors, it increases surface area and forces airflow to keep temperatures under control, while the light blue finish adds a tidy visual touch.
The combination of passive fins and an integrated fan reduces temperature spikes during sustained high demand. This helps maintain torque and avoids thermal cutback in competitive or extended running sessions.
Fitting is straightforward and compatible with most 540 can motors. Once mounted it holds securely so you get dependable cooling even on rough tracks.
