Thermal Management for Competitive 540 Motors

For racers and tuners, the 3Racing 3RAC-MHS005/LB fan-shaped heat sink with fan provides a compact method to control motor thermals. Engineered to interface with standard 540 motor outlines, the assembly uses directed airflow to reduce peak case temperature and support repeatable performance during tuning runs.

Technical Highlights

  • Compatibility: Matches the common 540 can dimensions used in both stock and modified setups.
  • Active Cooling: Integrated fan increases convection across the fin stack to limit thermal build-up during sustained loads.
  • Durable Finish: Light blue anodised aluminium resists surface wear and assists heat transfer from the housing.

What should I verify before fitting to a tuned motor?

Confirm can diameter, endbell profile and shaft clearance, and ensure the fan has unobstructed airflow for effective cooling when used with higher power setups.

Can this be part of a tuning package to reduce thermal rollover?

Yes, adding forced-air cooling helps maintain consistent temperatures during repeated runs, which supports stable motor behaviour and more predictable tuning outcomes.

Any installation notes for race teams?

Use appropriate fasteners, check balance and clearance, and route fan wiring to avoid heat sources or moving parts to maintain reliability in race conditions.
