3Racing 3RAC-MHS5/TI/V2 Titanium Fan Sink for 540 Motor  [3RAC-MHS5/TI/V2]

High Capacity Cooling for 540 Motors

If you push your 540 motor hard, the 3Racing 540 Motor Titanium Heat Sink with Fan is built to keep temperatures down. The titanium construction gives a strong yet light profile, while the integrated fan promotes steady airflow to reduce thermal stress during long or intense runs.

Titanium Strength with Improved Heat Flow

Titanium's balance of low weight and good conductivity makes this heat sink a practical upgrade. It maintains consistent motor temperatures under load, which helps avoid performance drop off and preserves component life.

Tailored Fit for Standard 540 Units

The shape and mounting of this sink are matched to standard 540 dimensions for close contact and efficient heat transfer. It is a straightforward swap for racers and hobbyists looking to add active cooling without major chassis changes.
