Hobbywing Fan Combo C4 (Heat Sink + 5v Fan) For 44mm Motor

The Hobbywing Fan Combo C4 (Part No: HW86080130) is a heavy-duty thermal management system specifically designed for large-scale brushless motors with a 44mm diameter. This size is the standard for 1/8 scale motors, such as the Hobbywing EZRUN 4274 or XERUN 4268/4274 series. By combining a massive, high-surface-area aluminum heatsink with a high-velocity 5V fan, the C4 combo prevents motor overheating during aggressive 4S–6S bashing sessions or long main events on the race track.

Key Features:

• Large-Scale Cooling: The heatsink is specifically contoured to fit 44mm cans (also commonly referred to as "42mm series" motors when accounting for the cooling fins), providing maximum contact for heat dissipation.
• High-RPM Cooling Fan: Includes a durable 5V fan that provides consistent airflow even in dusty or high-vibration environments typical of 1/8 scale off-road racing.
• Secure Tension Fit: The wrap-around aluminum design acts as a spring, clamping firmly onto the motor to ensure it won't shift during jumps or hard impacts.
• Modular Design: The fan is mounted with standard screws, making it easy to replace with a higher-voltage or larger-capacity fan if your setup requires extreme cooling.
• Protective Fan Grille: Features an integrated cover to prevent larger debris or stray wires from making contact with the spinning fan blades.

Pro-Level Setup Tip:

Since 1/8 scale vehicles often run High Voltage (HV) servos at 7.4V or 8.4V, the receiver ports will also output that higher voltage. Do not plug the 5V C4 fan directly into an HV receiver port, as it will significantly shorten the fan's life or burn it out instantly. Instead, use a Hobbywing 6V-to-5.3V Step-Down Regulator or connect the fan to a dedicated 5V BEC output to ensure long-term reliability.
