About this model
The Antminer S21 Hydro is the liquid-cooled version of the S21, delivering 319 TH/s at 5104W. Water cooling keeps BM1370 chips stable even under high load, with noise levels staying below 35 dB.
S21 Hydro repair combines work with cutting-edge 5nm electronics and hydraulic circuit servicing. We perform component-level hashboard repair (chip replacement, trace restoration, VRM repair), cooling system service and repair (seal testing, flushing, pump and gasket replacement), and control board diagnostics and repair.
Bring your S21 Hydro in for diagnostics — we work with next-gen hydro models.
Common issues
Hashrate drops below 290 TH/s — BM1370 chip degradation or thermal contact issues with water block
Coolant leak from circuit — seal wear or micro-crack on fitting
Pump making unusual sounds — cavitation, worn bearing, or air in the circuit
Uneven temperature across hashboard — partial water block channel clogging
Control board not responding on network — network controller crash or firmware damage
