Targeted cooling for competitive 540 motors

The 3Racing Extended Motor Heat Sink with Fan is engineered for racers who need predictable thermal control from their 540-class motors. It lowers steady-state temperatures to reduce motor power roll-off during sustained high load operation.

Lightweight aluminium body with forced-air cooling

CNC-friendly aluminium construction provides a high surface area for heat transfer while the integrated fan creates directional airflow across the motor can. This reduces thermal gradients and helps maintain consistent RPM under long runs.

Fitment and tuning considerations

The assembly is compatible with standard 540 can dimensions and installs without permanent motor modification. When tuning, consider fan voltage and mounting position to optimise airflow and clearances for your specific chassis and gearing choice.

What tuning benefits does active cooling provide?

Active cooling keeps motor temperatures lower, which stabilises magnetic and winding behaviour and reduces thermal sag, giving more repeatable lap times and predictable throttle response.

How should I integrate the fan with my power system?

Run the fan from a regulated low-voltage source or a switched output; ensure the voltage matches the fan rating. For race use, consider wiring the fan to be active only when the vehicle power is on to avoid unnecessary drain.

Are there setup tips for maximising cooling efficiency?

Position the unit to allow unobstructed airflow, clear debris regularly, and check that fan voltage and motor clearance align with your gearing and chassis layout for best results.
