About this model
The Antminer S21+ Hydro is a high-performance liquid-cooled S21 model delivering 358 TH/s at 5370W. Its 15 J/TH efficiency and minimal noise make it optimal for large deployments with centralized water cooling.
Repair covers the full cycle: component-level hashboard work (BM1370 chip and VRM element replacement, trace restoration), liquid circuit servicing (seal integrity, flushing, pump and gasket replacement), and control board diagnostics and repair. We have experience with hydro models from both generations — S19 and S21.
Bring your S21+ Hydro in — we'll restore stable operation at full hashrate.
Common issues
Hashrate below 330 TH/s — chip degradation or water block contamination reducing heat transfer
Coolant leak at quick-connect fittings — worn O-ring seals
Pump can't maintain adequate pressure — clogged filter or worn impeller
Emergency shutdown when coolant exceeds 45°C — insufficient external radiator capacity
Communication errors between hashboards — oxidized connectors in humid environment
