Key Features & Performance Highlights
-
Massive 395 TH/s Footprint Expansion: Delivering close to 400 terahashes from a single high-density physical enclosure, this hardware maximizes rack-space utility. It allows large-scale mining operations to multiply their cluster capacity without expanding their overall facility floor layout.
-
Elite Advanced Hydro Thermal Exchange: By swapping standard high-rpm chassis fans for custom internal liquid conduits, the S21+ Hydro draws heat directly away from the custom ASIC chips. This superior thermal transfer maintains optimal chip operating junctions, limiting degradation and keeping computing states steady.
-
Silent 50 dB Acoustic Blueprint: Traditional high-velocity fans produce deafening ambient acoustics. The water-driven internals of the S21+ Hydro lower the noise floor to a whisper-quiet 50 decibels, creating comfortable workspace management and facilitating localization closer to residential grids if needed.
-
Industrial Infrastructure Ready: Operating via 3-phase power delivery (380-415V) and supporting strict water-quality parameters (deionized, pure water, or verified antifreeze mixes), this system pairs seamlessly with standard container solutions like ANTSPACE or custom dry-cooler radiator arrays.
