Antminer S21 / T21 Silver Industrial Silencer – Pure Copper AC Blower for 120mm Square 4pin Chassis
Quiet your Antminer S21 or T21 with the heavy industrial pick — silver metal housing, full pure-copper AC capacitor motor, 1750/2000 CFM airflow ceiling. Both miners share the same chassis architecture (4× 120mm fans on square 4pin connectors) so this single silencer covers both. Bundle includes the matching square 4pin × 4 fan simulators for your control board.
Why the Silver Industrial Series
Heavy-duty platform: silver metal housing, robust pure-copper AC motor, fixed 1150 RPM, 1750 CFM airflow. Best for permanent installs, dense single-rig setups, longevity-first buyers. The Silver Industrial pairs the silencer to your miner via your own duct work — flexible and reusable across chassis. Compact discrete alternative? See our Antminer S21 / T21 Black Mini Silencer.

Install Workflow
Power the S21 or T21 off and unplug from mains. Remove the 4 stock 120mm fans. Plug a square 4pin fan simulator into each control board fan header (4 fans, 4 simulators — included). Duct the silencer's 150mm outlet to the miner exhaust using your own flexible coupler. Power up, monitor hashboard temperatures for the first hour at full hash, verify thermal spec is held.
