is the miner boxed in any way (soundproofed)? 59 DB is amazing and the power consumption I simply love. Is the sound perceived next to the miner (like 1 ft away?) or in the house?
I am
not familiar with m20s at all, does it have like a low power function on him?
thank you

There is no sound proofing on the miner. It has two high speed 140mm fans on both ends. At standard mining speed the noise ramps up high and makes a very loud hum noise that I can hear in my house with the miner in the garage. I lined the walls of the garage that attached to main part of the house with 2 inch acoustic sound proofing to minimize noise. An S9 I had in there running I could barely hear. The M20S at 69Th/s and fans at over 4000 RPM I can hear very clearly and it was annoying the wife. But I put it on the low power setting and it's all good. Can't hear it at all. If I stand in the garage I hear a low hum noise from it and that's it. So happy wife, happy life.
