Antminer S19k Pro / S19a Silver Industrial Silencer
The Silver Industrial silencer dedicated to the Antminer S19k Pro and S19a. These two SHA-256 miners share a less common cooling layout: four 120mm fans split between two connector types on the same control board — 2 × square 4-pin and 2 × linear 4-pin. We ship a mixed fan simulator kit (2 + 2) matched to that layout.
Choose between a 200W motor at 1750 CFM or a 300W motor at 2000 CFM depending on ambient temperature, duct length and operating profile.
Why a mixed connector kit matters for S19k Pro and S19a
Standard silencer kits ship with four identical fan simulators (all square or all linear). On the S19k Pro and S19a, plugging the wrong connector type causes the firmware to flag "fan error" or "low RPM" warnings even when the external blower is cooling correctly — sometimes throttling the miner below rated hashrate. Our kit ships exactly what the control board expects: 2 × square 4-pin + 2 × linear 4-pin fan simulators.
Pure copper continuous-duty AC motor
The Silver Industrial uses a metal-housed pure copper-core AC motor rated for continuous 24/7 operation. The 200W variant delivers 1750 CFM (sufficient for standard residential garage installations); the 300W variant delivers 2000 CFM (for warm climates, long exhaust ducting or higher-back-pressure layouts).
Acoustic performance
Stock S19k Pro and S19a noise level: typically 75-80 dB at 1 m. With the Silver Industrial installed and properly ducted: 50-60 dB at 1 m. The metal housing handles high-static-pressure operation without resonance buzz that compact plastic enclosures can produce.
