The 3Racing 3RAC-MHS008/PU in purple is designed to enhance cooling on 540 motors by combining a shaped heat sink with an active fan. This pairing helps manage temperatures during repeated high-load runs.
The fan forces air across the expanded fin area and the fan-shaped form increases surface contact for quicker heat escape. The assembly is made to stand up to routine competitive and club use.
Compatible with a broad range of 540 motors, this heat sink is an easy upgrade for drivers who want more consistent motor temperatures. Always check clearance and wiring space when fitting to your chassis.
