About Antminer S15
The Antminer S15 is Bitmain's air-cooled model, released in November 2018. At 57.0 J/TH it ranks #94 of 99 in the catalog by efficiency, and 43rd of 48 among air-cooled machines.
At 76 dB and 1.5 kW it needs a data center or a dedicated ventilated room, not a living room. It comes in hashrate variants from 17 to 28 TH/s; this page uses the manufacturer's nominal 27 TH/s.
