Bitmain Antminer S21e Hydro Bitcoin Miner

Bitmain Antminer S21e Hydro Bitcoin MinerThe Bitmain Antminer S21e Hydro 310TH/s is a high-performance hydro-cooled ASIC miner engineered for professional Bitcoin mining operations demanding maximum uptime, thermal stability, and serious SHA-256 computational power.Delivering an impressive 310TH/s hashrate at 5270W power consumption, the S21e Hydro is designed for miners scaling commercial operations where air-cooled systems begin struggling with heat management and efficiency consistency.Unlike conventional air-cooled ASIC miners that turn mining facilities into industrial wind tunnels, the Antminer S21e Hydro uses advanced liquid cooling technology to maintain optimized operating temperatures while improving overall hardware stability and operational efficiency.Because profitable Bitcoin mining gets considerably harder when your hardware is busy cooking itself alive.Key BenefitsMassive 310TH/s SHA-256 Bitcoin mining performanceAdvanced hydro cooling for improved thermal efficiencyStable 24/7 mining operation for commercial environmentsOptimized for Bitcoin (BTC) and SHA-256 cryptocurrenciesReduced thermal stress compared to traditional air coolingIndustrial-grade reliability for mining farmsEthernet connectivity for stable network deploymentBuilt for scalable high-performance mining infrastructureWhy Choose the Antminer S21e Hydro?As Bitcoin mining difficulty continues increasing, operational efficiency and thermal management become just as important as raw hashrate. The Antminer S21e Hydro addresses both.Hydro cooling allows the S21e to maintain more consistent operating temperatures under sustained workloads, reducing heat buildup while supporting long-term mining stability. For large-scale mining farms, this means improved deployment density, better thermal control, and more predictable performance across demanding environments.This miner is purpose-built for professional operators who understand that cooling efficiency directly impacts profitability, uptime, and hardware lifespan.Perfect ForCommercial Bitcoin mining farmsIndustrial crypto mining facilitiesHydro-cooled mining systemsLarge-scale SHA-256 mining operationsProfessional BTC miners scaling infrastructureHigh-density mining deploymentsAdvanced Hydro Cooling AdvantagesTraditional air-cooled miners create excessive heat, fan noise, and airflow management problems at scale. The Antminer S21e Hydro utilizes liquid cooling technology to transfer heat more efficiently, helping operators maintain cleaner, more stable mining environments.The result is improved thermal consistency, quieter operation at the rack level, and better overall cooling efficiency for high-output Bitcoin mining systems.In other words, less screaming fan noise and significantly less thermal drama.Built for Professional Mining OperationsThe Antminer S21e Hydro is engineered for miners operating dedicated facilities with appropriate hydro-cooling infrastructure and high-voltage power configurations. Its combination of extreme hashrate and advanced cooling makes it an ideal solution for competitive Bitcoin mining environments where performance consistency matters.If you’re building a serious mining operation, this is the kind of hardware designed to keep up.Key Features & SpecsFeatureDetailsManufacturerBitmainModelAntminer S21e HydroAlgorithmSHA-256Hashrate310TH/sPower Consumption5270WCoolingHydro CoolingVoltage380–415VInterfaceEthernetNetworkRJ45 Ethernet 10/100MOperating Temp20°C – 50°CHumidity10–90% RHStorage Temp-20°C – 70°CSize (No Package)339 × 176 × 208mmSize (With Package)570 × 316 × 430mmNet Weight12.8kgProduct AttributesAttributeOptionBrandBitmainModelS21e HydroMiner TypeHydro ASIC MinerAlgorithmSHA-256CoinsBitcoin (BTC)Cooling TypeHydro CoolingConnectivityEthernetVoltage380–415V   Antminer S21e Hydro profitability calculator Frequently Asked Questions Is a power cord included with the miner TBD How much overclocking is possible with Antminer S23? TBD I'm not getting the advertised efficiency on stock settings. Is there something wrong with my miner? Mining efficiency is highly dependent on ambient air temperature. If your miner is pulling more power than expected, in most cases it is due to a higher ambient temperature. You can improve mining efficiency by preventing mixing of hot exhaust air with intake air.  Which control board does this miner come with? TBD Can you ship this directly to my hosting company? Yes, you can either take delivery yourself or ship this to your hosting company by providing their address under the shipping address field on checkout page.  Can you recommend a reputable hosting company? While we do not have our own hosting facility, as a Bitcoin mining hardware vendor, we regularly ship ASIC miners and repair parts to various hosting sites across the US. Here’s a list of some of the companies we’ve worked with:–BSLF Mining–Terra Hosting–Wilson Mining This list is a recommendation and not an endorsement for these hosting companies. Please do your own due diligence, before choosing a colocation host. You can do further research on hosting companies on hashbranch.com Who should I contact if there's a problem with my miner?
