YSIDO 36mm Alloy Heat Sink Fan for 1/10 RC Cars - High Speed 26000 RPM Cooling Fan for 540 550 3650 3660 Brushless Motors (Red)
This YSIDO 36mm alloy heat sink with integrated cooling fan is built to help keep 1/10 scale RC car motors from overheating. It fits 36mm diameter motors like 540, 550, F540, 3650, 3660, and 3665 brushless types. The fan reaches up to 26,000 RPM for strong airflow, and the 20cm cable makes installation straightforward.
Fits Common 36mm RC Motors
The heatsink and fan combo is sized for motors with a 36mm diameter, a standard size for many 1:10 RC cars, trucks, buggies, and crawlers. It works with brushed motors like the 540 and 550, and brushless motors such as the 3650, 3660, and 3665 series. If your motor measures 36mm across, this cooling set is made for it.

Installation and Power
Power the fan from a spare port on your receiver — no separate battery needed. The plug is non-polarized, so you can connect it either way and it will still spin. Mount the heatsink to the motor using the provided hardware (if included) or thermal tape. The 20cm cable gives you room to route it neatly in your RC chassis.
Frequently Asked Questions
Will this fan fit a 540 motor?
Yes, the 540 motor’s can diameter is 36mm, exactly what this heatsink is designed for.
Can I use it with a 3660 brushless motor?
Yes, the 3660 series has a 36mm diameter and is compatible.
Does the plug have a correct polarity?
No, the connector works regardless of which wire goes where. Wrong connection won’t hurt it.
What voltage does the fan need?
It operates on 5 to 8.4 volts, so standard receiver voltage (around 5-6V) or a 2S LiPo (7.4V) works fine.
