Antminer Black Mini Silencer — S19, S19 Pro, S19j, T19, D7, DR7, E11, KA3, KS3, HS3, E9, E9 Pro
The compact Black Mini silencer for the Antminer legacy family with four 120mm linear 4-pin cooling fans — 12 different miner models across Bitcoin, Decred, Ethash, Kadena, Kaspa legacy and Handshake algorithms. Same acoustic platform as our Silver Industrial fiche, in a smaller plastic housing for tight installation spaces.
Choose 300W or 400W AC motor before ordering. Each motor includes an on-unit High / Medium / Low speed switch.
Compact form factor for closet, rack and shelf installations
The Black Mini Standard fits where the Silver Industrial cannot: equipment closets, rack-mount cabinets, under-shelf positions and ceiling-mounted above the exhaust port. Lighter plastic housing makes wall-mounting straightforward.
AC motor with speed switch — 300W or 400W
The 300W and 400W are two distinct AC motors chosen via Shopify variant before ordering. Each includes a 3-position speed switch (High / Med / Low) on the unit itself, allowing in-place tuning of airflow vs. noise without firmware modification.
Linear 4-pin fan simulators + exhaust adapter included
Ships with 4 × linear 4-pin Antminer fan simulators matched to the legacy control board layout, plus a universal exhaust adapter that mates the blower intake to the miner exhaust port without custom fabrication. No fan-error alarms after installation.
Acoustic performance — residential garage compatible
Stock legacy Antminer noise: typically 75-80 dB at 1 m. With Black Mini Standard installed and proper ducting: 52-62 dB at 1 m. Performance depends on ambient temperature, duct length, room volume and miner load.
