Antminer S19k Pro / S19a Black Mini Silencer
The Black Mini silencer dedicated to the Antminer S19k Pro and S19a — same mixed connector cooling layout as our Silver Industrial fiche, in a compact plastic housing for tight installation spaces. Ships with the matched mixed fan simulator kit (2 square + 2 linear 4-pin).
Choose 300W or 400W AC motor before ordering. Each motor includes an on-unit High / Medium / Low speed switch for fine-tuning airflow vs. noise.
Compact form factor for rack and closet installations
Where the Silver Industrial requires open space, the Black Mini Standard fits inside equipment closets, shelving units and small rack-mount cabinets. The plastic housing is lighter and easier to wall-mount or ceiling-mount near the miner exhaust port.
AC motor with speed switch
Both 300W and 400W variants are distinct AC motors (not a single switchable motor) — choose the spec before ordering. The on-unit speed switch lets you trim airflow down during cooler hours or lower hashboard load.
Mixed connector fan simulator kit included
S19k Pro and S19a use two different fan connector types on the same board. Our kit ships 2 × square 4-pin + 2 × linear 4-pin fan simulators matched to that layout, so the firmware reads four valid signals and does not throw fan-error alarms. A universal exhaust adapter is also included to mate the blower intake to the miner exhaust port.
Acoustic performance
With the Black Mini installed and proper ducting: stock 75-80 dB at 1 m typically drops to 52-62 dB at 1 m. Compact housing favors low-frequency hum over fan tonal noise.
