Race focused cooling for 540 motors

The 3Racing 3RAC-MHS004/RE High Finger Heat Sink with Fan is developed for racers who need consistent motor performance over heat intensive sessions. The red finish is matched to a compact fin profile and fan that target hot spots on standard 540 cans.

Performance oriented features

  • Track Ready Construction: Engineered for repeated use and quick service intervals.
  • Active Cooling Strategy: Fan driven airflow reduces core temperature to help maintain consistent power output.
  • Fast Setup: Mounts cleanly to the common 540 footprint for minimal fitting time at the pits.
  • High Visibility Finish: Red anodising helps with bike shedding and quick visual ID during events.

What setup checks are recommended before an event?

Verify motor external diameter and mounting alignment, confirm fan wiring polarity, and ensure fins are free of residue for optimal airflow during competition.

Can this help with thermal consistency over multiple heats?

Yes, by lowering running temperature the heat sink with fan reduces thermal drift between heats, helping to keep lap times more consistent across runs.

Any tuning tips for competitive use?

Keep the fan and fin surfaces clean, check for secure mounting after practice, and consider motor cooling when selecting gearing to avoid thermal cutbacks in longer finals.
