Race-Ready Cooling for 540 Motor Setups

The 3Racing 540 Motor Cooling Heat Sink with Fan is aimed at reducing motor case temperature during sustained running. This black heat sink with built-in fan is compatible with typical 540 motors and helps maintain consistent performance during long runs or competitive events.

Performance Advantages

Effective cooling can prevent power sag and reduce wear on motor components. The 3Racing heat sink channels forced air across the fins to accelerate heat loss from the motor shell, offering practical benefits for racers and hobbyists pushing their setups.

Compatibility and Fitting

Fitting is straightforward and requires only basic tools, making this a sensible upgrade for most 540 motor installations. Its broad compatibility makes it suitable for a range of RC cars from touring to off-road where extra cooling is needed.

Can this heat sink be used on heavily modified motors?

It can be used on many modified 540 motors provided the shaft and mounting allow for the heat sink to sit correctly; always confirm dimensions before fitting.

Does the fan draw power from the ESC or a separate supply?

The fan normally needs its own feed and is often wired to the receiver or a dedicated auxiliary source to avoid overloading the ESC supply paths.

Is there any regular servicing required?

Regular checks for debris in the fins and ensuring the fan spins freely will keep the cooling working effectively; replace or repair the fan if bearings become noisy or stiff.
