The 3Racing 540 Motor Cooling Heat Sink with Fan 3RAC-MHS004/BL is designed to draw heat away from the motor can and expel it via a dedicated fan. This pairing helps maintain consistent motor temperatures during long or demanding use.
Engineered for 540 motors, the cooling unit reduces thermal fatigue that can degrade performance over time, helping to keep motors reliable between services. The black styling blends with most builds while serving a clear functional role.
Fitting the 3Racing unit is quick and intuitive, providing secure contact without obstructing adjacent components. The compact form delivers airflow where it matters with minimal impact on chassis layout.
