Antminer S19 S19 Pro T19 Silver Industrial Silencer Blower 200W/300W — S19j D7 DR7 E11 KA3 KS3 HS3 E9 E9 Pro

Antminer Legacy Linear 4pin Silver Industrial Silencer — S19, S19 Pro, S19j, T19, D7, DR7, E11, KA3, KS3, HS3, E9, E9 Pro

The Silver Industrial silencer blower for the broad Antminer legacy family that shares a common cooling architecture: four 120mm linear 4-pin cooling fans. One blower platform serves 12 different miner models across Bitcoin SHA-256, Decred SHA-256d, Ethash, Kadena Blake2s, Kaspa kHeavyHash legacy and Handshake Blake2b algorithms.

Choose 200W (1750 CFM) or 300W (2000 CFM) AC motor before ordering, depending on ambient temperature, duct length and operating profile.

One silencer for the whole legacy linear 4-pin Antminer family

The S19, S19 Pro, S19j, T19 series, D7, DR7, E11, KA3, KS3, HS3, E9 and E9 Pro all use the same control board fan layout: four 120mm fans with linear 4-pin connectors. The Silver Industrial replaces all four with one high-volume blower channelled through an acoustic-lined plenum.

Pure copper continuous-duty AC motor

The Silver Industrial uses a pure copper-core AC induction motor in a rugged metal housing, rated for continuous 24/7 operation. The 200W variant delivers 1750 CFM (standard home / small-fleet); the 300W variant delivers 2000 CFM (warm climates, long exhaust runs, higher back-pressure layouts). The blower curve is matched to typical legacy Antminer hashboard back-pressure (3 hashboards × respective ASIC stack) so cooling headroom stays intact.

Linear 4-pin fan simulators included — no firmware alarms

The kit ships 4 × linear 4-pin Antminer fan simulators. Plug into the stock fan headers so the firmware reads four valid PWM signals and does not throw "fan error" or "low RPM" alarms (which on some models throttle the miner below rated hashrate).

Acoustic performance — residential garage compatible

Typical stock noise for this miner family: 75-80 dB at 1 m. With the Silver Industrial installed and proper exhaust ducting: 50-60 dB at 1 m — within residential garage compatible envelope. The acoustic-lined plenum attenuates high-frequency fan tonal noise; the metal housing damps motor hum and structural vibration.
