Antminer S21 / T21 Black Mini Silencer – Compact Brushless DC with Dedicated Exhaust Adapter
Quiet your Antminer S21 or T21 with the compact home pick — black plastic housing, brushless DC motor with stepless speed knob, sized for the 120mm fan chassis of the S21 / T21. The bundle includes a dedicated 120mm exhaust adapter that mates the Black Mini outlet to the S21 / T21 chassis exhaust — no flexible-duct fiddling, plug-and-play seal. Heavy industrial alternative? See our Antminer S21 / T21 Silver Industrial Silencer.
Why the Black Mini Series
Compact home platform: black engineering-plastic shell, brushless DC motor with stepless speed knob (1800-7000 RPM), low-vibration low-weight design. Best for home installs, mobility, acoustic tunability, and discrete form factor. The included exhaust adapter is sized to your miner's chassis (120mm in this case) — install is plug-and-play.
What's in the Box
- 1 × Black Mini blower silencer (brushless DC, 1300 m³/h, stepless 1800-7000 RPM)
- Dedicated exhaust adapter for Antminer S21 / T21 (120mm fan chassis)
- Power cable matched to your selected plug (US / EU / UK / CN)
- 4 × square 4pin fan simulators
Pair with the Right Fan Simulator (if you need additional units)
Install Workflow
Power off, unplug, remove the 4 stock 120mm fans. Plug a square 4pin fan simulator into each control board fan header. Attach the included exhaust adapter to the miner chassis, then mate the Black Mini outlet to the adapter — no flexible duct required. Power up, set the stepless knob for your ambient room temperature, monitor hashboard temperatures for the first hour, trim down for silence once thermal spec is confirmed.
