This aluminium motor heat sink with integrated cooling fan is an aftermarket RC-scale accessory designed for the TRAXXAS Slash 4x4 Lcg version. The assembly combines a finned aluminium sink and a dedicated fan to move air across the motor can, helping control operating temperature during extended or high-load running.
Functionally, the unit is intended to reduce motor heat soak that can affect performance and longevity in on-road and off-road RC sessions. It is a component-level cooling aid rather than an electronic modification, so its effectiveness depends on mounting position, airflow path, and secure electrical connection of the fan.
Installation notes: confirm clearance around the motor can, pinion and spur gear, and any nearby suspension or chassis features before fitting. Secure the heat sink to the motor using the motor's existing mounting points where applicable, route the fan wiring clear of moving parts and drivetrain, and verify fan rotation and airflow direction before final assembly. Adjust placement to avoid interference with the gearbox, ESC, and chassis components.
When matched to the Slash 4x4 Lcg layout and installed with proper clearance and wiring, this heat sink and fan set provides a practical way to manage motor temperatures during sustained RC use.
