Whatsminer M30 / M31S / M32 Series Mini Silencer – Compact AC Motor (Choose 300W or 400W) with Dedicated 140mm Exhaust Adapter
Quiet the entire legacy Whatsminer lineup — M30 / M30S / M30S+ / M30S++, M31S / M31S+ / M31S++, and M32 / M32S — with a single Black Mini Standard silencer. All nine sub-models share the same chassis (2× 140mm fans, square 4pin) so a single unit + 140mm adapter covers the whole legacy lineup. Black plastic, AC capacitor motor in your choice of 300W or 400W. Bundle includes 140mm exhaust adapter + 2 × square 4pin fan simulators. Heavy alternative? Silver Industrial version.
Why a Single Silencer for M30 / M31S / M32 Legacy
These three Whatsminer generations share identical chassis form factor. A single Black Mini Standard + 140mm adapter kit covers all nine sub-models — useful if you operate a mixed series rack.
Choose Your Motor — 300W or 400W
300W AC motor: quieter, moderate ambient. 400W AC motor: higher airflow ceiling. Each motor has its own multi-position speed switch.

Install Workflow
Power off, unplug, remove the 2 stock 140mm fans. Plug a square 4pin fan simulator into each control board fan header. Attach the included 140mm exhaust adapter to the miner chassis, then mate the Black Mini outlet to the adapter — plug-and-play seal. Power up, set the speed switch on the motor to a middle position for initial install, monitor temperatures for the first hour. Trim the speed switch up or down once thermal margin is confirmed. Same procedure across all 9 sub-models.
