Thermal management for competitive 540 motors

For racers seeking cleaner thermal behaviour from 540-size motors, the 3Racing Motor Heat Sink with Fan provides a compact fan-fin profile that aids convective cooling. The black finish keeps the package low-key while the design concentrates airflow where the motor needs it most during long runs or high load stages.

Technical highlights for tuning

  • Compatibility: Geared for 540 size motor cans commonly used in competition
  • Material: Aluminum construction to move heat away from the can quickly
  • Design: Fan-shaped fin array to promote consistent airflow across the motor barrel
  • Color: Black finish suitable for race-oriented builds

How does this sink affect lap-to-lap temperature stability?

The fan-shaped fins enhance airflow, helping the motor shed heat more effectively between runs and improving repeatable performance under repeated high-load laps.

Can this be used alongside other cooling mods?

Yes, it pairs well with external ducting or a small forced-air fan to further lower peak temperatures in aggressive race setups.

Any notes for setup and weight considerations?

The sink is a lightweight addition that trades minimal mass for improved thermal control; ensure secure mounting and verify clearance to avoid interference with gearing or chassis parts.
