Bitmain Antminer L11 Hyd 6U 33G

The Bitmain Antminer L11 Hyd 6U (also known as Antminer L11 Hyd HU6 or L11.HU6) is a high-end, hydro-cooled (liquid-cooled) ASIC miner from Bitmain’s L11 series, released in late 2025 (first batches around October–December 2025). It’s optimized for the Scrypt algorithm, making it excellent for mining Litecoin (LTC) and Dogecoin (DOGE) via merged mining, plus other compatible coins like BELLS, JKC, LKY, PEP, and more. The 6U rack format and hydro cooling make it suited for large-scale professional or data center operations, offering better thermal management, lower noise, and sustained performance in dense setups compared to air-cooled models.

Key Specifications

• Hashrate: 33 GH/s (gigahashes per second)
• Power Consumption: 5676 W (typical on-wall at 25–35°C)
• Efficiency: ~0.172 J/MH (or 172 J/GH) — strong for Scrypt in its class
• Algorithm: Scrypt (LTC, DOGE merged mining, plus BELLS, JKC, LKY, PEP, etc.)
• Cooling: Hydro/liquid cooling (requires external coolant loop with antifreeze, pure water, or deionized water; inlet temp typically 20–50°C, low pressure)
• Noise Level: ~50 dB (significantly quieter than air-cooled equivalents due to no high-RPM fans)
• Dimensions: Approx. 400 × 195 × 290 mm (without PSU); larger with packaging/PSU (~570 × 316 × 430 mm)
• Weight: Net ~50 kg (heavy-duty build for rack stability)
• Rack Format: 6U (designed for standard server racks in farms or data centers)
• Power Input: 220–277V (single-phase in some listings; check for 3-phase compatibility in setups)
• Connectivity: RJ45 Ethernet (10/100M)
• Operating Conditions: Temp 5–45°C, humidity 5–95%
• Other Features: Supports pool mining (e.g., NiceHash, ViaBTC); Bitmain monitoring interface; robust for 24/7 high-density deployment

Features and Use Case

This is an enterprise-grade miner — not for home use due to its enormous power draw (~5.7 kW!), weight, rack size, and requirement for a dedicated hydro-cooling infrastructure (pumps, radiators, coolant management). The liquid cooling excels in hot environments or dense racks, reducing fan noise and preventing thermal throttling for reliable long-term operation. It’s ideal for professional farms focused on merged LTC + DOGE mining (earn both coins on one hashrate). Profitability varies with coin prices, difficulty, and power costs — at current estimates (as of mid-January 2026), it can generate ~$20–$25+ daily revenue before electricity (e.g., via NiceHash), but high US East Coast rates like in New Jersey (~$0.15–$0.20/kWh or higher) mean daily power costs could run $20–$30+, so low-cost power is essential.

Pricing and Availability

Reseller prices range from ~$9,000–$17,000 USD depending on batch, condition, and vendor (e.g., ~$9,630 on some sites; official Bitmain spot was higher around $16,995 before selling out). It’s widely available through ASIC specialists like CryptoMinerBros, ViperaTech, ASIC Miner Value partners, and others, with ongoing stock in 2026. First batches shipped late 2025, and it’s part of the broader L11 Hydro lineup (including the higher-hash 2U/35G variant).

Compared to the earlier 35G HU2 (2U, slightly higher hashrate but similar power), this 6U model prioritizes density and cooling efficiency for bigger operations. Versus home Bitcoin miners like the NerdQaxe+ Hydro or Canaan Nano, this is pure industrial Scrypt power.
