36mm RC Motor Heatsink & Fan for 540, 550, 3650 & 3660
Add airflow around a compatible RC motor during your next build or maintenance job. This aluminium heatsink and fan fits suitable 36mm motors in 540, 550, 3650 and 3660 formats. It is for RC car owners with room for an external cooling assembly.
- ✅ Move air around the motor — The powered fan directs airflow over the heatsink.
- ✅ Fit cooling into a compact build — A motor-mounted assembly keeps the fan close to the motor body.
- ✅ Use a suitable receiver supply — The fan can draw power from a compatible receiver connection.
- ✅ Keep your existing motor — The assembly adds cooling hardware without replacing the motor itself.
A motor-mounted cooling addition for your RC car
The aluminium heatsink fits around a suitable motor body, with the fan mounted above it. Check the motor diameter and clearance beneath the body shell before fitting.
The fan is specified for a 6V supply, with a stated maximum of 7.4V. Match the receiver output and connector to the fan rather than connecting it directly to an unsuitable battery supply.
One blue heatsink with cooling fan is included. This is a cooling accessory; the motor, receiver, battery and complete car are not included.
