Noise of around 75–80 dB is unbearable in the long run in a flat, an office or a house with children. If you just throw a blanket over the machine or shut it in a cupboard, you usually trade noise for heat: the miner starts sucking in its own hot air, the chips overheat, the fans spin up even more and the machine throttles or shuts down.\u003c\/p\u003e\n\u003cp\u003eA good soundproofing box therefore has to do two things at once – absorb sound and let the miner breathe freely. Our boxes have separate cold and hot zones, an upward exhaust and four layers of sound-absorbing materials.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to look for when choosing a box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow.\u003c\/strong\u003e Cold and hot air must not mix.
