Bitmain Antminer S21 Hyd (335Th) Antminer S21 Hydro 335T

The Bitmain Antminer S21 Hyd (335Th) is a purpose-built SHA-256 workhorse that pushes 335 TH/s while drawing 5,360 watts, yielding roughly 16 J/TH and throwing off essentially the same amount of heat as its power draw, so plan to shed about 5.3 kilowatts of thermal energy per unit into your cooling loop or room air; its defining trait is a sealed hydro-cooling circuit using deionized or otherwise ultra-pure water to carry heat away more evenly than air, which lowers chip temperatures, reduces thermal cycling and stress, and lengthens component life while keeping acoustic output down to about 50 dB so rows of machines need not sound like a factory floor. Compact at 339 x 163 x 207 mm, it fits densely into industrial racks and can be deployed where floor space is at a premium, but installation demands attention: robust electrical distribution, redundant power supplies or breakers, properly sized pumps and heat exchangers or chillers for the water loop, leak detection and quick-disconnect plumbing, and routine water chemistry maintenance to prevent corrosion or biological growth. Rated to operate between roughly 5 and 45 °C and across wide humidity ranges, the S21 Hyd sustains consistent hashrate under continuous load and benefits operations that prioritize steady uptime and lower fan wear; because hydro units concentrate heat into a liquid stream, facility HVAC design can be simplified or centralized but must handle the concentrated thermal load safely. For Bitcoin and other SHA-256 coins it delivers competitive throughput with fewer noisy fans to manage, and its engineering emphasis on stable temperatures, compact footprint, and robust cooling components makes it well suited to large-scale farms that can invest in centralized chillers and water-management infrastructure-practicalities include planning for power-factor and breaker sizing, accessible network ports for monitoring and firmware updates, and serviceable mounting that lets technicians swap units without draining an entire rack; in short, the S21 Hyd trades the simplicity of air-cooled boxes for higher density, quieter operation, and longer-lived hardware when paired with the correct facility support, a little like a stubborn old tractor that only asks for clean water and a steady hand to keep on working.

Under a clinical neon glaze the Bitmain Antminer S21 Hyd 335Th presents itself as a purpose-built SHA-256 engine-rated at 335 TH/s with a draw of 5,360 watts and an efficiency hovering around 16 J/TH-its character defined by a sealed hydro loop that channels deionized or ultra-pure water to strip heat directly from cold plates and hashboards, cutting thermal cycling, lowering junction temperatures and materially extending component life compared with air-cooled boxes; the closed-loop circuit uses industrial-grade, leak-resistant hydraulic connectors and quick-disconnect plumbing, and the unit’s integrated hashboard monitoring and custom firmware support let operators tune hashrate stability, monitor anomalies in real time and push firmware updates over accessible network ports without ripping racks apart. Compact at 339 x 163 x 207 mm and whispering about 50 dB, the S21 Hyd is built for dense racks where acoustic footprint and fan wear matter, and it tolerates a broad environmental envelope (roughly 5–45 °C and 5–95% relative humidity), but it trades the plug-and-play simplicity of air-cooled boxes for a set of infrastructure requirements: properly sized pumps and heat exchangers or a centralized chiller to absorb the roughly 5.36 kW of heat per unit, robust electrical distribution with attention to breaker sizing and power factor correction, leak detection and water-chemistry maintenance to prevent corrosion or biological growth, and serviceable mounting so technicians can swap units without draining an entire loop. For planning purposes, the thermal load can be translated into hydraulic terms-assuming a 5 °C temperature rise across the heat exchanger, a single S21 Hyd needs on the order of 0.256 liters per second (≈15 liters per minute) of coolant flow; allowing a 10 °C delta roughly halves that demand-so pump sizing, plumbing diameter and chiller capacity should be calculated from expected rack counts, not individual units. Operational features like low-voltage operation and enhanced thermal-throttling algorithms reduce heat loss and prevent runaway temperatures during sustained loads, while cold-plate technology maximizes direct heat transfer; in practice these design choices let facility HVAC be simplified or centralized, but only if the water-management architecture-pumps, filters, reservoirs, heat exchangers and redundancy-can safely handle the concentrated thermal stream and maintenance routines are in place to keep the loop clean and conductive.
