3Racing 3RAC-MHS4/LB/V2 540 Motor Fan Cooler Light Blue  [3RAC-MHS4/LB/V2]

Cooling upgrade for 540-class motors

The 3Racing 3RAC-MHS4/LB/V2 light blue cooling system is built to reduce temperatures on 540 motors so your setup runs more consistently under load. It is aimed at drivers who need reliable thermal control during extended sessions without adding unnecessary bulk.

Active fan driven heat removal

An integrated fan forces airflow across a precision heat sink to pull heat away from the motor casing. The combination of directed airflow and finned surface area helps limit temperature spikes and keeps RPM and torque delivery stable during demanding use.

Low mass with solid construction

Made from lightweight components, this 3Racing cooling unit adds minimal weight while resisting everyday wear. The light blue finish provides a clean look that fits with many custom builds and does not interfere with mounting or wiring in compact chassis layouts.
