For model drivers focused on consistent lap times, the 3Racing 540 Motor Extended Heat Sink with Fan offers a compact cooling upgrade. Made to suit standard 540 motors, it increases the finned area and adds a fan to help regulate temperatures, with a light blue finish that complements many builds.
The extended surface plus active cooling lowers the risk of thermal throttling when motors are running hard. That leads to steadier performance and helps extend motor life under frequent high demand.
Mounting is simple using basic tools and the unit fits the majority of standard 540 motors. Once fitted it stays secure so cooling remains effective on rougher runs and tight racing lines.
