Competition minded cooling for 540 cans

The 3RACING 3RAC-MHS001/PU purple heat sink is intended for 540 can motors, delivering consistent thermal management under extended high load conditions. It is a practical part for racers wanting predictable cooling behaviour.

High-finger profile for improved airflow

The extended finger geometry raises the effective surface area and encourages airflow across the motor can to reduce operating temperature. The finish aids part identification in a busy pit area.

Fitment and quick serviceability

Designed to suit most 540 motors, the unit keeps mass low to avoid impacting vehicle dynamics. Installation is rapid, letting teams fit or remove the sink during routine setup changes.

How does this help during long race heats?

By increasing surface area and airflow, the sink helps slow temperature rise so motor performance remains more consistent over long runs.

Any tuning trade offs to consider?

The sink is lightweight, but teams should check clearances and ensure it does not interfere with timing belts, sensors or nearby components.

Recommended maintenance between events?

Inspect for dust build up, ensure screws remain secure, and clear any debris that could restrict airflow to keep cooling consistent.
