Asic Miner Silencer Manual Control – Compatible with Antminer S21 Pro, S21+, L11 (140mm Fan)

ASIC Miner Silencer Fan with 5-Speed Manual Controller

(Free Fan Simulator Included)

The ASIC Miner Silencer Fan with 5-Speed Manual Controller is engineered to significantly reduce mining noise while delivering powerful and adjustable cooling for high-load ASIC miners. Featuring a manual speed control system, users can set the fan speed according to outlet air temperature and mining load, ensuring efficient heat dissipation and stable operation.

Driven by a 400W high-stability motor, the fan provides a maximum airflow of up to 1100 m³, achieving an approximate temperature reduction of 10°C per hash board. Noise levels range between 60–70 dB, depending on the selected speed, making it suitable for both home and professional mining environments.

The fan is built with heavy-duty industrial-grade plastic for long-term durability. A double-bearing structure ensures smooth, low-noise rotation and extended service life, while the pure copper motor delivers high efficiency, strong torque, and consistent cooling performance during continuous operation.

The package includes a fan simulator, shroud, and installation screws, enabling easy installation and compatibility with multiple ASIC miner platforms.
