Practical Cooling for 540 Motor Builds

The 3Racing 540 Motor Cooling Heat Sink with Fan provides active cooling to reduce motor temperatures in demanding driving. The black fan-mounted heat sink is sized for standard 540 motors and delivers targeted airflow to the motor case to slow thermal rise during prolonged sessions.

Why add the 3Racing Heat Sink

Improved heat control keeps power delivery more consistent and reduces wear on motor internals. The integrated fan pushes air through the fins to assist heat dispersion, which is especially useful for high-speed runs and heavy duty use.

Installation Guidance

Mounting the 3Racing heat sink is designed to be accessible to hobbyists and tuners. It is compatible with most 540 motors, making it a convenient upgrade for racers and weekend builders who want steadier motor temperatures.

Do I need to modify my motor to fit this heat sink?

In most cases no major modification is required, but verify your motor shaft and mounting pattern to ensure a correct fit and secure attachment.

Where is the best place to power the fan from?

Common practice is to use the receiver or an auxiliary supply compatible with the fan voltage; check your setup and avoid drawing excessive current from sensitive circuits.

Will this affect my car balance or weight distribution?

The unit is lightweight and sits on the motor, so it has minimal impact on overall balance but always recheck its clearance and mounting to prevent interference with nearby components.
