Antminer Silver Industrial Silencer — L9, AL1/AL1 Pro, KS5/KS5 Pro, S19j XP
The Silver Industrial silencer blower is engineered for the modern Antminer family that uses four 120mm square 4-pin cooling fans on the control board. It fits the Antminer L9 (Litecoin Scrypt), AL1 and AL1 Pro (Kaspa kHeavyHash), KS5 and KS5 Pro (Kaspa kHeavyHash) and S19j XP (Bitcoin SHA-256). One acoustic platform — six miner models, one connector kit.
Choose between two AC motor variants before ordering: a 200W motor at 1750 CFM for standard home / small-fleet noise reduction, or a 300W motor at 2000 CFM for higher back-pressure ducting runs and warmer ambient environments.
Why the Silver Industrial fits the Modern Antminer Square 4pin family
L9, AL1, AL1 Pro, KS5, KS5 Pro and S19j XP share the same control board layout: four 120mm cooling fans with a square 4-pin connector. The Silver Industrial replaces all four stock fans with a single high-volume blower routed through an acoustic enclosure. The blower curve is matched to typical miner back-pressure (4-channel hashboard stack), preserving cooling headroom while cutting fan tonal noise by 15-25 dB at 1 meter.
Pure copper continuous-duty AC motor
The blower uses a pure copper-core AC motor in a metal housing rated for continuous 24/7 operation. Both motor variants (200W / 300W) deliver high static pressure for ducted exhaust and are suitable for closet, garage or basement deployments. The metal housing dissipates motor heat without thermal throttling.
Fan simulators included — no error codes
The kit includes 4 × square 4-pin Antminer fan simulators. Plug them into the original fan headers on the control board so the firmware reads four valid PWM signals and does not throw "fan error" or "low RPM" alarms while the external blower handles cooling.
Acoustic performance and operating envelope
Typical stock noise: 75-80 dB at 1 m. With the Silver Industrial installed and proper exhaust ducting: 50-60 dB at 1 m. Performance varies with ambient temperature, duct length, room volume and miner load. For residential garage or shed installation, 200W is usually sufficient; for warm climates or long exhaust runs, choose 300W.
