The Antminer S21+ HYD utilizes the SHA-256 algorithm, primarily for mining Bitcoin (BTC) and Bitcoin Cash (BCH). It delivers a maximum hash rate of 319 TH/s with a power consumption of 4785W. This results in an industry-leading power efficiency of approximately 15 J/TH.
The core difference lies in thermal management. The S21+ HYD uses a liquid-cooling loop to dissipate heat, allowing it to maintain higher densities and potentially lower operational noise compared to the air-cooled S21+, which relies on high-speed fans. This makes the HYD version ideal for warehouses with centralized cooling infrastructure.
Due to its 4785W draw, this miner typically requires a three-phase 380–415V power input, as it utilizes a high-voltage PSU design to minimize transmission losses. It is not compatible with standard residential 110V or 240V outlets without significant electrical upgrades.
While Bitmain often configures models differently, the S21 series typically utilizes a 3-hashboard architecture. The HYD version maintains this layout, but the boards are mounted to a liquid-cooled cold plate rather than an aluminum fin stack.
A solid red LED indicates a critical fault where the miner has halted hashing. You must immediately check the kernel log via SSH or the web interface for specific errors. Common causes for the HYD version include loss of coolant flow or pump failure, triggering an over-temperature protection.
Unlike air-cooled miners where fans fail frequently, the HYD version’s most common issues are micro-cracks in the water-cooling plates or leaks at the quick-disconnect fittings. Always inspect your coolant loops for drips and ensure the coolant has anti-corrosive properties to prevent galvanic corrosion between the aluminum plates and copper fittings.
