Q: Is this miner suitable for a beginner?
A: While incredibly powerful, the M73 requires existing hydro-cooling infrastructure. It’s best suited for miners already familiar with liquid-cooled systems or those working with a professional hosting provider.
Q: How does hydro-cooling benefit me compared to air cooling?
A: Hydro-cooling offers three major benefits: 1) Much lower noise (75dB), 2) Superior cooling efficiency leading to more stable hash rates and longer hardware life, and 3) Enables higher-density setups as heat is removed via liquid, not air.
Q: What is needed to run the WhatsMiner M73?
A: You need three core things: 1) A hydro mining rack or compatible cooling loop with pump and heat exchanger, 2) A stable 220-240V power circuit capable of 7.63kW, and 3) Standard Ethernet network access.
Q: Can I achieve the maximum 526 TH/s consistently?
A: Achieving the maximum hash rate depends on optimal conditions: perfect coolant flow and temperature, stable clean power, and ideal ambient conditions. The 470-526 TH/s range accounts for real-world operational variances.
Q: Is the efficiency gain worth the hydro system complexity?
A: Absolutely. For serious miners, the 14.5 J/TH efficiency, combined with quieter operation and hardware longevity, provides a lower total cost of ownership and higher lifetime profitability compared to less efficient, louder air-cooled alternatives.
