Compact cooling for 540 motors

The 3Racing Extended Motor Heat Sink with Fan is designed to bring down operating temperatures on 540-class motors. This upgrade helps keep motor temps in check during sustained high load runs, extending component life and stabilising output.

Durable construction and steady airflow

Made from robust aluminum, the heat sink dissipates heat quickly while the built-in fan maintains a steady airflow across the motor surface. Together they reduce the risk of thermal cutback and deliver more reliable performance under race conditions.

Universal fit and simple install

Engineered for standard 540-sized motors, the unit fits a wide range of on-road and off-road setups and installs with basic tools. Its compact footprint makes it useful for tight motor bays and common hobby mounting arrangements.

Will this fit brushless and brushed 540 motors?

Yes. The 3Racing heat sink suits standard 540 form factor motors whether brushed or many common brushless cans, as long as the physical dimensions match the mounting area.

Do I need extra wiring for the fan?

The fan typically runs from a small battery or switched supply depending on your setup. Check the fan voltage rating and wire it to a compatible power source or a switched lead if you want it to run only when the vehicle is on.

Will the heat sink change gear mesh or fit in tight trays?

The design is compact to avoid interfering with pinion or spur gear positions in most standard layouts, but it is recommended to check clearance in your chassis before final installation.
