ASIC Miner Blower Silencer Gen2 Installation Manual

Created 2025/5/16

The blower silencer Gen2 suits Antminer (except S21XP S21pro y S21+), Whatsminer, Avalon, and Iceriver ASIC miners. It is an efficient heat dissipation and noise reduction solution for cryptocurrency mining equipment. Its step-less speed control switch and brushless DC motor deliver excellent heat dissipation and energy-saving performance. This document outlines the usage tutorial for the Gen2 blower silencer.

I. Read before the operation

• Tools and accessories preparation:

Product gift: fan speed simulator, several screws

Self-provided: A screwdriver

• Anti-static protection: Wear an anti-static wrist strap or touch grounded metal when handling the control board or electronic components.

• Power off operation: To avoid high-voltage electric shock, turn off the miner and unplug the power cord before installation.

• Environmental requirements: Ensure a dry, non-flammable environment below 40°C.

IV. Maintenance and troubleshooting

Daily maintenance:

• Clean the surface and interior of the blower silencer Gen2 monthly to remove dust.

• Keep the usage environment ventilated and dry.

• Regularly inspect the tape and hose clamps for aging and replace them promptly.

• Check cables for damage or aging to prevent electric shock hazards.

• Tighten loose screws immediately.

Common Problems

Solutions

The mining machine reports "fan failure"

Check whether the PWM speed regulator is compatible, plugged in the wrong way, or has poor contact.

Noise suddenly increases

If the muffler impeller is dusty, it needs to be cleaned, or the bearing needs to be replaced if it is severely worn.

Insufficient heat dissipation

Increase the PWM speed or check the air guide cover connection to maintain sealing.
