For racers focused on consistent lap times, the 3Racing Gold Heat Sink with Fan is a practical cooling upgrade for 540 motors. The design pulls heat away from the motor body, helping limit temperature rise during extended or heavy use. Its fan-style fin layout increases airflow across the motor shell without adding complex wiring.
Manufactured to withstand frequent use, the gold finish resists wear while giving a clean appearance in the bay. Whether fitting this as part of routine maintenance or a setup tweak for competition, the heat sink helps maintain steady motor temperatures and protect internal components.
