Technical Cooling Upgrade for 540 Motor Setups

The 3Racing Engine Heat Sink Extended Motor Heat Sink with Fan Ver.2 provides targeted thermal management for 540 motor cans, combining an extended fin profile with an integrated fan to increase convective heat transfer. The anodised black finish is low profile and the design supports repeatable temperature control across qualifying and race runs.

Engineering and Performance Notes

  • Compatibility: Optimised for standard 540-size motor cans to ensure consistent mounting and thermal contact.
  • Design: Extended fin geometry increases convective surface area while the fan forces airflow across critical motor surfaces.
  • Material: Manufactured from robust components to withstand frequent track use and tuning adjustments.
  • Installation: Straightforward attachment allows rapid fitment and minimal setup change between runs.

How does the 3RAC-MHS7/BL/V2 affect motor temperature stability?

By increasing surface area and adding forced airflow, the unit reduces peak temperatures and narrows temperature variance between runs, aiding in predictable motor behaviour.

Are there tuning changes I should consider after fitting this heat sink?

Cooling improvements can allow more aggressive timing or higher sustained loads; monitor motor and ESC temperatures during test laps and adjust settings incrementally.

What installation checks are recommended for race use?

Verify secure mounting, tidy wiring to avoid interference, and confirm fan power routing. Recheck fasteners and clearances after initial installation and between race days.
