Black Mini Gen2 Brushless DC Silencer — 140mm Fan Adapter for Whatsminer M20/M30/M50/M60 Series
The premium Gen2 brushless DC silencer blower dedicated to the Whatsminer industrial lineup. Pre-fitted with a 140mm fan exhaust adapter matched to the Whatsminer 2-fan chassis layout: M20/M20S/M21/M21S, M30/M31S/M32, M50/M50S/M50S+/M50S++, M60/M60S/M60S+/M60S++. One blower covers the full Whatsminer SHA-256 generation history.
Whatsminer 2-fan chassis vs Antminer 4-fan
Unlike Antminer S21 family (4 × 140mm fans), Whatsminer industrial miners use a fan chassis with 140mm intake/exhaust ports. The Gen2 silencer ships with the matched 2-port adapter — no spacing mismatch, no air leak. The bundle requires only 2 fan speed simulators (vs 4 for Antminer), lowering total deployment cost.
Why Gen2 Brushless DC vs Gen1 AC capacitor
The Gen2 brushless DC motor replaces the AC capacitor motor of our Black Mini Standard (Gen1). Benefits over Gen1:
- 30-50% energy savings vs AC capacitor at equivalent airflow
- Stepless speed knob — continuous wind regulation, vs Gen1's 3-position fixed switch
- 50Hz / 60Hz universal input — runs identically on US, EU, UK, AU power grids without burning the motor
- Lower acoustic floor — variable frequency lets you reduce noise further during cooler hours or lower hashboard load
- Brushless = no carbon brushes — extended lifetime, no brush wear
- Smaller compact size than Silver Industrial — lower shipping costs and easier handling
Whatsminer compatibility — multi-generation
The 140mm × 2 adapter fits the entire Whatsminer industrial lineup spanning M20 (legacy) through M60 (current gen):
- M20 series : M20, M20S, M21, M21S — legacy SHA-256
- M30 series : M30, M31S, M32 — mid-gen SHA-256
- M50 series : M50, M50S, M50S+, M50S++ — modern SHA-256
- M60 series : M60, M60S, M60S+, M60S++ — current-gen SHA-256
All Whatsminer industrial generations share the same 2 × 140mm chassis footprint. The Gen2 silencer is a future-proof investment that follows your Whatsminer rig through upgrade cycles.
Easy installation
Remove the 2 original Whatsminer fans, plug a fan speed simulator into each of the 2 fan headers (Whatsminer 4-pin or 6-pin depending on your model), mate the blower exhaust to the included 140mm × 2 adapter, connect 220V power. Operational in 10 minutes. Cooling effect after install : approximately -10°C on Whatsminer internal temperature.

- Whatsminer 4-pin Fan Speed Simulator (P21/P221/P222 PSU)
- Whatsminer 4-pin ATX Fan Speed Simulator
- 6-pin Whatsminer Fan Speed Simulator (M31/M31S)
- 6-pin Universal Innosilicon/Whatsminer Simulator
