Hobbywing Fan 5015sh 8v 70,000 RPM 0.20a Black A0 (Max4 Hv)

The Hobbywing Fan 5015SH (Part No: HW86080131) is an ultra-high-speed cooling fan specifically engineered as the factory replacement for the EZRUN MAX4 HV ESC. Operating at a staggering 70,000 RPM, it is one of the most powerful fans in the Hobbywing lineup, designed to handle the extreme thermal demands of 1/5 scale heavy-duty vehicles running 8S to 12S LiPo setups.

Key Features:

• Extreme Velocity: Rated at 70,000 RPM, this fan provides the massive static pressure required to force air through the dense heatsink fins of the MAX4 HV, ensuring stable operation even under 300A+ current loads.
• HV Optimized (8V): Specifically tuned to run on an 8.0V supply (the standard BEC output for large-scale ESCs), maximizing airflow without the risk of premature motor failure found when over-volting 5V or 6V fans.
• Solid-State Durability: Despite its high speed, the "SH" designation indicates a reinforced bearing system designed to survive the chassis-slapping jumps and high vibrations typical of vehicles like the Traxxas XRT or Arrma Kraton 8S.
• Black A0 Aesthetic: Features a stealthy all-black finish and a compact 50mm housing (5015 frame size) that integrates seamlessly into the MAX4 HV's protective fan shroud.
• Low Power Draw: Efficiently pulls only 0.20A, allowing the ESC's BEC to prioritize power for high-torque steering servos while maintaining maximum cooling.

Maintenance Tip:

Due to its incredibly high rotational speed, the 5015SH can be sensitive to small debris like sand or pebbles. Always ensure the protective grille on your MAX4 HV is securely fastened. If you notice a high-pitched "whining" or a decrease in speed, use compressed air to clean the hub area. Note: Never plug this fan into a standard 5V receiver port if you expect full performance; it requires the full 8V output from the MAX4's fan port to reach its rated 70,000 RPM.
