Cooling Upgrade for Competitive 540 Setups

The 3RACING 3RAC-MHS008/RE is intended as a performance-minded cooling upgrade for 540 motors, combining an expanded fin area with an integrated fan to lower motor temperatures under continuous load.

Airflow-focused Geometry

The fan-shaped layout directs airflow across the motor can and increases convective heat transfer. This helps reduce thermal drift in setups where temperature consistency is important for lap-to-lap repeatability.

Practical Use in Tuning and Race Prep

As a compact cooling solution, it fits into common 540 motor installations and supports racers who want to manage thermal load without complex modifications. Its design helps maintain motor performance over longer runs and repeated heats.

How should I verify fit before installing?

Measure the motor can diameter and check available clearance in your chassis; confirm the fan has unobstructed airflow path to get full cooling effect.

Does this influence motor tuning choices?

Lower operating temperatures can support more consistent performance, which may affect gearing and timing decisions as you tune for repeatable lap times.

Any installation cautions for race cars?

Ensure the heat sink does not foul nearby gears or suspension parts, secure it to prevent movement, and confirm the fan rotor is clear of wiring or chassis edges.
