Hobbywing Fan Combo C1 (Heat Sink + 5v Fan) For 36mm Motor

The Hobbywing Fan Combo C1 (Part No: HW86080120) is a high-efficiency cooling solution designed for 36mm diameter brushless motors, such as the 3650, 3660, and 3674 series. It features a lightweight, wrap-around aluminum heatsink paired with a high-RPM 5V cooling fan. This combo is an essential upgrade for 1/10 scale off-road bashers and high-speed touring cars, as it significantly reduces motor temperatures to prevent thermal fade and extend the lifespan of the magnets and internal bearings.

Key Features:

• Precision Clamp-On Design: The 36mm aluminum heatsink provides a snug, high-contact fit against the motor can, ensuring maximum heat transfer away from the internal coils.
• High-Flow 5V Fan: The included 5010HB cooling fan is optimized for 5V operation, making it easy to power directly from an open receiver port or a dedicated BEC.
• Durable Aluminum Housing: The heatsink is CNC-machined to be both rigid and lightweight, providing structural support for the fan while maximizing the surface area for air cooling.
• Universal Compatibility: While optimized for Hobbywing EZRUN and QUICRUN 36mm motors, it will fit any standard "540" or "550" sized motor with a 36mm outer diameter.
• Easy Installation: Features a simple "snap-on" or "slide-on" tension fit that requires no specialized tools, though it can be secured with additional zip-ties for extreme high-vibration applications.

Installation Tip:

For the most effective cooling, ensure the heatsink is mounted in a position where the fan is not obstructed by the vehicle's body or wiring. If you are running a 3S LiPo or higher, be careful not to plug the 5V fan into a high-voltage (HV) port; if your receiver is powered by 7.4V, you may need a Step-Down Regulator or a different fan to prevent burning out the motor. If your motor is larger (44mm diameter), you should look for the Combo C4 instead.
