Practical cooling for 540 motors

The 3RACING 3RAC-MHS001/PU purple heat sink is aimed at 540 motors to curb heat during heavy running. It is a simple performance-minded fit for off-road rigs and basher builds.

High finger form improves airflow

The pronounced finger profile increases the exposed surface area to help dissipate heat from the motor can. The purple coating also makes the sink easy to find in the pit box.

Broad fitment and quick upgrade

Designed to match the dimensions of most 540 motors, this sink keeps added weight to a minimum so handling is maintained. It installs quickly with basic tools for minimal downtime.

Is this suitable for rock crawling or heavy duty use?

It helps with heat control under heavy load but check clearance in tight motor bays common on crawler setups.

Should I use thermal paste or adhesive?

Many users fit the sink directly; if desired, a thin thermal interface material can improve contact but is not essential for basic use.

Will it change motor balance or add drag?

The unit is lightweight and should not noticeably affect motor balance or increase drivetrain drag.
