• Power Consumption: 5500-5800W, power efficiency ratio as low as 172-179 J/GH. At 30℃ ambient temperature, the core temperature is stably controlled below 65℃, 18-22℃ lower than air-cooled models​

• Heat Dissipation System: Hybrid design of water-cooled main control (custom heat sink fins + high-efficiency water pump, flow rate 1.2L/min) + air-cooling auxiliary (4 sets of quiet fans, speed 3800 RPM), reducing noise level to 60 dB​

II. Deployment Recommendations and Limitations​

2.1 Optimal Use Cases​

Medium-Large Mining Farms: The L11 Pro’s balance of performance and cost makes it ideal for batch deployment (100+ units). At
​0.05/kWh, The payback period is reduced to 12 months.

Low-Electricity-Cost Regions: Recommended for areas with electricity rates ≤$0.08/kWh. Above this threshold, the higher power consumption (vs. DG2+) may erode profitability.​

2.2 Operational Limitations​

Noise Restrictions: 75 dB noise levels require industrial-grade sound insulation or outdoor deployment. Residential use is strongly discouraged.​

Cooling Dependencies: In high-humidity environments (>80%), monthly maintenance of fan filters is necessary to prevent dust accumulation and overheating.​

CONCLUSION​

The Bitmain Antminer L11 Series stands as a testament to the ongoing evolution of Scrypt mining technology, delivering iterative advancements that cater to diverse miner needs—from enhanced hashing power and class-leading energy efficiency (as low as 172 J/GH) to adaptive cooling solutions tailored for every scale. Whether selecting the entry-level L11, the efficiency-focused L11 Pro, or the high-density L11 Hyd 6U, each model delivers consistent, industry-leading performance specifically optimized for Dogecoin (DOGE) and Litecoin (LTC) mining—two of the most widely mined Scrypt-based cryptocurrencies.​

For small-scale operators, home miners, or those new to Scrypt mining, the air-cooled Standard L11 and L11 Pro shine: they require minimal setup (compatible with 19-inch standard racks) and low maintenance (weekly fan filter checks), while still delivering reliable hashrates (18.5–19.2 GH/s for the Standard, 20.1–20.8 GH/s for the Pro) and efficiency that outperforms legacy models like the Antminer L9. In contrast, the L11 Hyd 6U redefines large-scale mining potential: its 6U rack design, 31.5–32.3 GH/s peak hashrate, and ultra-low 60 dB noise level (vs. 75 dB for air-cooled models) make it a standout for dense, noise-sensitive data center deployments—cutting space costs by 44% compared to air-cooled clusters of the same Computing power.​

Beyond raw performance, the L11 Series’ longevity is anchored in thoughtful engineering: refined PSU compatibility (supporting 220–277V single-phase input for flexibility), feature-rich firmware (including OTA updates and dual-mode performance tuning), and robust environmental adaptability (operating reliably at 5–45°C). These attributes ensure consistent output even under demanding conditions—critical as Scrypt network difficulty continues to rise .
