Thermal Control for Competitive 540 Motors

For racers tuning motor performance, the 3Racing fan-shaped heat sink combines an aluminium heat path with targeted airflow to reduce temperature rise during sustained loads. The compact form factor and light blue finish suit tuned touring and 1/10 scale race builds while keeping weight and frontal area low.

Technical Advantages

  • Durable Construction: Machined aluminium body ensures consistent thermal conduction and resilience to track use.
  • Enhanced Cooling: The integrated axial fan raises convective cooling over passive sinks, helping maintain power output under race conditions.
  • Race-Friendly Design: Low profile shape and secure mounting help preserve chassis balance and drivetrain clearance.
  • Quick Installation: Fits standard 540-size motor cans for fast upgrades during setup changes.

What effect does active cooling have on motor longevity?

Active airflow lowers peak operating temperatures which reduces thermal stress on windings and magnets, contributing to more consistent performance and longer component life when used correctly.

How should I integrate the fan with my wiring and BEC?

Route the fan feed to a regulated source that matches its voltage rating; consider a filtered supply or switched channel to prevent interference with sensitive telemetry and to protect the receiver from excess load.

Does the sink affect gear alignment or motor mount position?

The sink adds external diameter and some depth to the motor assembly, so verify pinion mesh and motor mount clearances after fitting to maintain drivetrain integrity.
