3Racing 3RAC-MHS5/BL/V2 Black 540 Motor Fan Heat Sink  [3RAC-MHS5/BL/V2]

High Performance Cooling for 540 Class Motors

The 3Racing 540 Motor Cooling Heat Sink with Fan is built to keep motor temperatures in check during spirited runs. This black fan-mounted heat sink suits standard 540 motors and helps control heat build-up during long sessions or fast laps. Its low-profile styling also blends with most RC models while improving thermal performance.

Benefits of the 3Racing Cooling Unit

Keeping a 540 motor cool reduces thermal stress and improves consistency on the track. The 3Racing heat sink combines a fin array with active fan airflow to move heat away from the motor case, lowering the chance of thermal cutback and extending component life. It is a practical upgrade for racers and regular club drivers alike.

Simple Fitment and Wide Compatibility

Fitting the 3Racing unit is straightforward and requires minimal tools, making it a friendly upgrade for both experienced tuners and hobbyists. The design matches most common 540 motor sizes so you can swap it into many touring cars, buggies, or basher builds for better cooling performance.
