MicroBT WhatsMiner M70S (226Th/s)

The MicroBT WhatsMiner M70S represents the ultimate evolution of air-cooled Bitcoin mining, engineered exclusively for the SHA-256 algorithm to deliver elite-tier performance for Bitcoin (BTC). Released in December 2025 as the enhanced "S" variant of the acclaimed M70 series, this flagship air-cooled miner leverages cutting-edge 5nm chip technology to achieve a formidable hash rate of 226 Th/s while drawing just 3140W of power, resulting in an exceptional energy efficiency of 13.894 J/Th. This remarkable efficiency metric positions the M70S as one of the most profitable air-cooled miners on the market, offering operators a superior return on investment without the complexity or infrastructure requirements of liquid cooling.

Engineered with MicroBT's hallmark precision and durability, the WhatsMiner M70S shares the same space-optimized footprint as its predecessor, measuring 430 x 155 x 226mm and weighing 13,500g. This compact, rack-friendly chassis delivers unmatched hash rate density, enabling operators to maximize their computational output per square meter in multi-tier rack configurations. The advanced thermal management system, powered by two high-speed fans, ensures optimal heat dissipation during continuous 24/7 operation while maintaining a consistent noise level of 75dB—a practical and expected output for a machine delivering over 220 terahash of sustained computational force. Seamless connectivity is guaranteed through the standard Ethernet interface, providing low-latency communication and effortless integration with all major mining management platforms, including Braiins OS, Hive OS, and proprietary MicroBT dashboards.

What truly distinguishes the M70S from its predecessor is the refined 5nm silicon architecture, which unlocks additional hash rate headroom while maintaining identical power consumption—a testament to MicroBT's relentless pursuit of engineering excellence. This refined efficiency directly translates to superior profit margins, shielding your operation against market volatility and rising energy costs while future-proofing your fleet against network difficulty increases.
