Optimised Cooling for Competitive 540 Setups

The 3Racing 3RAC-MHS4/BL/V2 combines a compact heat sink body with a driven fan to improve convective cooling on 540 motors. The design targets more consistent motor temperatures under repeated runs, helping you retain performance across heats while maintaining a low profile fit.

Technical Highlights

  • Compatibility: Designed specifically for 540 motors
  • Material: High-quality construction for durability
  • Cooling Efficiency: Integrated fan for enhanced heat dissipation
  • Color: Sleek black finish

How should the fan be integrated into a race electronics stack?

Connect the fan to a dedicated ESC fan output where available or use a regulated auxiliary supply; ensure the wiring does not interfere with chassis components or create electrical noise in sensitive telemetry circuits.

Does the heat sink affect motor mounting or balance?

The unit mounts to the motor can and is designed to avoid altering shaft position; confirm pinion mesh and ensure the added mass is acceptable for your vehicle balance preferences.

What maintenance is recommended to keep cooling optimal?

Keep the fan and fins clear of debris, check the fan connector regularly for secure contact, and inspect the finish for any damage that might reduce airflow efficiency.
