🌪️ Powerful Airflow with Precision Control

With a maximum airflow of 210.38 CFM and static pressure of 21.60 mmH₂O, this cooling fan efficiently dissipates heat generated during intense mining operations. This high-pressure airflow is essential for maintaining safe temperatures, especially in tightly packed mining enclosures.

Thanks to the 4-wire PWM (Pulse Width Modulation) control, you can intelligently adjust fan speed based on system temperature or mining intensity. This results in better energy efficiency, quieter operation, and longer fan lifespan.

🔇 Optimized Noise Level – Balanced for Performance

Despite its powerful 6000 RPM speed, this fan operates at a manageable 64 dB-A, which is lower than many comparable high-performance mining fans. It delivers the airflow you need without being excessively loud, making it suitable for mining farms or acoustic-enclosed home setups.

Pair it with a good airflow path and optional noise-dampening enclosures for even better acoustic comfort.

🔩 Double Ball Bearing – Built to Last

The maintenance-free double ball bearing system ensures low wear and tear, reduced friction, and exceptional longevity. This fan is engineered for 24/7 operation, designed to perform under high temperatures and extended mining sessions.

Whether you’re mining in hot, dusty, or enclosed environments, this fan holds up – keeping your investment cool and productive.

🛠️ Easy Plug-and-Play Installation

The 4-pin standard connector fits directly into most Antminer hash boards or control boards, offering seamless installation without the need for adapters. Its universal 120mm x 120mm x 38mm size fits standard fan slots across most ASIC miners, making it a convenient replacement part or upgrade.

Installation is quick and tool-friendly, allowing even non-technical users to replace or upgrade their fans with ease.
