Better Cooling for Demanding Runs

The 3Racing 3RAC-MHS7/BU/V2 motor heat sink with fan is built to manage heat on 540 motors used in competitive or extended sessions. The fan forces air through the fin array to keep motor temperature down during heavy throttle periods. Reduced thermal stress helps preserve motor bearings and magnets while keeping power delivery more reliable.

Practical Advantages

Efficient Airflow: The included fan creates a directed stream of air to speed heat removal from the motor casing.
Solid Build: Engineered from durable materials to withstand regular club and race use.
Straightforward Upgrade: Fits standard 540 motor mounts for an easy swap.
Neat Finish: Blue anodising gives a tidy, performance-focused look.

Can I use this on brushed and brushless 540 motors?

It is suitable for both brushed and brushless 540-sized motors as long as the motor dimensions match the heat sink mounting area.

Will the fan impact my ESC or receiver?

The fan draws minimal current but confirm your electronics can supply the fan voltage and use the correct connector to avoid interference with control gear.

What basic checks should I do after fitting?

After installation, verify the fan spins freely, ensure no wires rub against moving parts, and run a short test to confirm the motor temperature behaviour under load.
