Practical cooling for high demand 540 motors

The light blue 3Racing 3RAC-MHS4/LB/V2 is intended to keep 540 motors within healthier temperature ranges so performance is consistent over longer driving periods. It is a straightforward upgrade for racers and weekend drivers alike.

Directed airflow for steady temperatures

The integrated fan forces air across a densely finned heat sink to accelerate heat transfer away from the motor shell. This focused airflow helps prevent thermal dips in power during repeated hard runs.

Durable finish and simple installation

Built for repeated use, the cooling assembly resists everyday wear while remaining easy to fit into common chassis layouts. The light blue finish offers a tidy visual match for many factory and custom builds.

Will this work with sensorless brushless setups?

Yes, it mounts around the motor can so it is compatible with many sensorless brushless 540 form factor motors, subject to dimension checks.

Is the fan polarity marked?

Fan wiring typically uses a positive and negative lead; confirm polarity before connecting to avoid reverse rotation, which reduces cooling effectiveness.

Can I run the fan continuously?

Continuous operation is acceptable if the voltage and current match the fan rating; many users leave the fan on for full-time cooling during sessions.

Any recommended maintenance routine?

Inspect wiring and blade condition regularly, clean dust from fins, and secure mounting screws to maintain steady cooling performance.
