Reduce Thermal Stress on 540 Motors with a Fan Assisted Heat Sink

The 3Racing Gold Extended Motor Heat Sink with Fan is built for 540 motors to improve heat removal under heavy loads. The fan-driven airflow and extended fins work together to keep the motor operating in its optimal range.

Designed for Continuous Performance

Active cooling reduces temperature peaks that can affect power and timing consistency, which is particularly helpful for long runs and high power setups. The gold finish is durable and tidy on most builds.

Compatibility and Simple Installation

This heat sink fits standard 540 can motors and mounts quickly, so you can get back to tuning rather than dealing with overheating. Good thermal contact and a secure fit are key to best results.

Will the fan draw extra battery current?

The fan requires a small amount of power, typically negligible compared to the motor draw, but factor it into lightweight setups or when powering accessories from the same source.

Should I use thermal adhesive or tape?

A thin thermal pad or paste improves conduction; use adhesive only if the design requires permanent mounting to avoid trapped air gaps.

Does the gold sink affect motor balance?

When mounted correctly and centred on the can, the sink should not introduce measurable imbalance. Check alignment during installation to be safe.
