The S21e Hydro delivers 320 TH/s at 16.5 J/TH, drawing 5280W with advanced liquid cooling. Hydro cooling enables quiet operation suitable for noise-sensitive facilities while maintaining excellent thermal stability under load. Requires dedicated water infrastructure with proper coolant management. Positioned between air-cooled S21 models and more expensive XP hydro variants, it offers a practical balance of hashrate, efficiency, and cooling costs. Professional-grade reliability for data centers seeking the thermal benefits of water cooling without the highest hashrate tier.
Key Features
- Industry-leading 16.5 J/TH energy efficiency
- Powerful 320 TH/s hashrate for maximum profitability
- Advanced thermal management with Hydro Cooling
- Easy setup and management via web interface
