Bitmain Antminer S21e Hydro 310T – Efficient Hydro-Cooled Bitcoin Miner

The Bitmain Antminer S21e Hydro 310T is a high-efficiency, water-cooled SHA-256 ASIC miner designed for serious Bitcoin (BTC) and Bitcoin Cash (BCH) mining. Delivering up to 310 TH/s of hashrate at around 5.27 kW power consumption, it’s built for miners who want strong performance, solid efficiency and stable 24/7 operation in a hydro-cooled setup.

Thanks to its hydro-cooling design, the S21e Hydro offers better thermal control, lower mechanical wear and significantly reduced noise compared to traditional air-cooled miners. It’s ideal for professional mining farms, hosting facilities and dedicated hydro-cooled installations where suitable power and cooling infrastructure is available.

What the Bitmain Antminer S21e Hydro mines

• Algorithm: SHA-256

• Primary coins:

  • Bitcoin (BTC)

  • Bitcoin Cash (BCH)

• Other SHA-256 coins (pool dependent):

  • Bitcoin SV (BSV) and various other SHA-256–based altcoins

You can direct the hashrate to any SHA-256 coin supported by your pool, although most miners use the S21e Hydro primarily for BTC.

Key features

• 310 TH/s SHA-256 hashrate
  Provides up to 310 terahash per second of SHA-256 performance in a compact hydro-cooled form factor, making it a strong option in the mid–high performance range.

• High efficiency at around 17 J/TH
  With a typical power draw of about 5 270 W, the S21e Hydro achieves efficiency in the region of around 17 joules per terahash, balancing hashrate and electricity cost for long-term mining.

• Hydro cooling for stable temperatures
  The integrated hydro-cooling system circulates coolant through the miner to keep chips within an optimal temperature range, enabling denser deployments and more consistent performance than air-cooled units.

• Much quieter than air-cooled miners
  With a typical noise level of around 50 dB, the S21e Hydro is significantly quieter than most high-end air-cooled ASICs. It is still best suited to dedicated mining or hosting environments, but the reduced fan noise is a major advantage.

• Designed for continuous 24/7 operation
  Built specifically for industrial and hosting environments, the S21e Hydro is intended to run around the clock when connected to suitable three-phase power and a properly sized water-cooling loop.

• Simple network configuration
  Uses a standard Ethernet interface. Connect it to your network, access the web interface, configure your mining pool and wallet details, and you’re ready to go.
