Antminer Mini Silencer — L9, AL1/AL1 Pro, KS5/KS5 Pro, S19j XP
The Black Mini silencer is the compact noise-reduction solution for the modern Antminer family with four 120mm square 4-pin cooling fans. Designed for tight installations (closet, equipment rack, under-shelf), it brings the same acoustic benefit as the Silver Industrial in a smaller plastic housing.
Choose between two AC motors before ordering: 300W (standard, suitable for most installations) or 400W (higher static pressure for warmer environments or longer ducting runs). Each motor includes a built-in High / Medium / Low speed switch for on-unit fine-tuning.
Compact form factor for tight installations
Where the Silver Industrial requires open space and metal enclosure mounting, the Black Mini Standard fits in shelving, equipment closets and rack-mount cabinets. The plastic housing is lighter (no metal cladding), making it easier to wall-mount or ceiling-mount above the miner exhaust.
AC motor with speed switch
Both 300W and 400W variants use an AC motor with on-unit speed switch (High / Med / Low). High mode provides full static pressure for warm-weather operation; Med and Low reduce airflow and noise during cooler hours or at lower hashboard load. The motor is rated for continuous 24/7 duty.
Includes square 4pin fan simulators AND exhaust adapter
The kit ships with 4 × square 4-pin Antminer fan simulators (plug into the stock fan headers to prevent firmware fan-error alarms) and a universal exhaust adapter to mate the blower intake to the miner exhaust port without leaks or custom fabrication.
Acoustic performance
With Black Mini Standard installed and proper exhaust ducting, typical noise drops from 75-80 dB at 1 m (stock) to 52-62 dB at 1 m. The compact housing shifts more high-frequency noise than the Silver Industrial; long duct runs reduce that further.
