Surpass Hobby 40mm RC Cooling Fan - 16000 RPM High Speed Motor Fan for 1/8 1/10 RC Cars Trucks Truggies (Without Heatsink)
This 40mm cooling fan from Surpass Hobby is built for 1/8 and 1/10 scale RC vehicles equipped with 4068-4082 brushless motors. It spins at up to 16000 RPM to help pull heat away from the motor, using forced air cooling. The fan works with brackets that have Φ3.2mm mounting holes and includes a reverse polarity protected plug to prevent damage from incorrect wiring. It runs on 5 to 8.4V and can be powered directly from the receiver.
How Fast Does This Fan Spin and What Voltage Does It Need?
The fan reaches a maximum rotational speed of 16000 RPM. It operates on a voltage range of 5 to 8.4V, making it compatible with standard receiver outputs on most RC models. The 18cm (7.09 inch) cable gives you flexibility in placement.
What Motors and Vehicles Does It Fit?
This fan is designed for 40mm diameter motors, specifically brushless motors in the 4068, 4074, and 4082 sizes. It's intended for 1/8 and 1/10 scale RC cars, trucks, and truggies. The fan itself is 40 x 10 x 10mm (1.5 x 0.39 x 0.39 inches) and weighs only 15g (0.53oz), so it won't add much weight. Note: This is a fan only – it does not include a motor heatsink.
