Thermal Control for 540 Motors using 3Racing 3RAC-MHS003/GO

Engineered with racing setups in mind, the 3Racing 3RAC-MHS003/GO Gold Fan-Shaped Heat Sink helps manage motor can temperature during sustained high load conditions. It is intended to aid thermal stability for 540 motors so performance is more consistent across runs.

Airflow Channeling and Heat Transfer

The fan-shaped profile directs airflow to increase convective cooling of the motor shell, assisting heat transfer away from internal windings during prolonged current draw. The finish provides surface protection while maintaining low-profile mounting.

Integration into Competitive Setups

Suitable for racers tuning motor and drivetrain balance, this heat sink is a practical option to reduce thermal drift. It is compact, compatible with standard 540 cans, and supports repeatable performance under race conditions.

What cooling gains can racers expect from this sink?

Gains depend on the full cooling setup and ambient conditions, but the fan geometry increases airflow over the can, which helps reduce steady state temperature during repeated runs.

Any fitting considerations for race-prepped motors?

Check the motor end profile and how the sink will be secured. Ensure it does not interfere with timing sensors or endcap components on tuned motors.

Is the finish durable under workshop maintenance?

The gold coating offers abrasion and corrosion resistance during regular handling, but avoid harsh abrasives when cleaning to preserve surface condition.
