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

ASIC Miner Silencer Fan with Intelligent Temperature Controller

(Free Fan Simulator Included)

The ASIC Miner Silencer Fan with Intelligent Temperature Controller is engineered to significantly reduce mining noise while delivering powerful and efficient cooling performance. Featuring an automatic temperature-based speed control system, the fan intelligently adjusts its RPM according to the outlet air temperature, ensuring optimal heat dissipation and stable miner operation under varying workloads.

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

Constructed with heavy-duty industrial-grade plastic, the fan is designed for durability and long-term continuous operation. The double-bearing structure ensures smooth, quiet rotation and extended service life, while the pure copper motor provides high efficiency, strong torque, and reliable thermal performance.

The package includes a fan simulator, shroud, and installation screws, allowing easy integration with various ASIC mining setups.
