Thermal Management for Competitive 540 Motors

The 3Racing Motor Heat Sink with Fan Ver.2 is engineered to aid temperature control on 540 motors used in competition. The high-finger red profile increases effective surface area to assist heat shedding during sustained high load operation.

Optimised Cooling for Setup Consistency

Constructed from aluminium to provide reliable thermal conduction, the heat sink directs heat away from the motor casing while the integrated fan maintains airflow across the fins to stabilise temperatures that affect tuning and performance consistency.

Designed for Tuning and Testing

In race prep and practice, consistent motor temperature helps with repeatable results. The 3Racing Motor Heat Sink with Fan supports longer testing windows by reducing thermal drift and lowering the chance of heat related performance variation.

What should I check before fitting to a race motor?

Verify the outer diameter and mounting points of your 540 motor, confirm clearance inside the motor bay, and ensure the fan voltage matches your power source to avoid electrical issues during race use.

Can this unit influence lap to lap consistency?

By reducing temperature variation the heat sink and fan can help maintain consistent motor behaviour across runs, which aids setup decisions and tyre management in competitive environments.
