Immersion Cooling System: Must be installed in a professionally designed immersion mining tank with compatible dielectric fluid, circulation pumps, and external heat exchangers.
Industrial Power Supply: Requires a stable three-phase AC power supply in the 380V – 480V range, with appropriate circuit protection and distribution.
Tank Integration: Miners are submerged; proper spacing and fluid flow management are critical for optimal cooling.
Network Connectivity: Waterproof Ethernet pass-throughs or wireless solutions are needed for network access within the immersion tank.
Fluid Selection & Maintenance: Use only recommended dielectric fluids and implement a regular fluid quality monitoring and filtration program.
Thermal System Design: Ensure your immersion system’s cooling capacity (flow rate, heat exchanger size) matches the total thermal load of your miners.
Professional Installation & Service: Deployment and maintenance in immersion systems require specialized knowledge and should be handled by qualified technicians.
Continuous Monitoring: Implement remote monitoring for hash rate, efficiency, and system temperatures to quickly identify any issues.
Q: How does the M76S differ from the standard M76?
A: The M76S is an upgraded model offering a higher hash rate (362-406T vs. 336-374T) and better efficiency (13.5 J/T vs. 14.5 J/T). It’s designed for miners who want the maximum performance and lowest operating cost within the M76 immersion series.
Q: Can I run the WhatsMiner M76S in an air-cooled or hydro-cooled setup?
A: No, absolutely not. The M76S is designed exclusively for immersion (oil) cooling. Attempting to operate it outside of a dielectric fluid bath will cause immediate overheating and permanent damage.
Q: What are “immersion or oil-bath mining setups”?
A: These are mining systems where ASIC miners are fully submerged in a tank of non-conductive, dielectric fluid. The fluid absorbs heat directly from the hardware, which is then cooled via external heat exchangers. This allows for extreme density, quiet operation, and high reliability.
Q: Why is the noise level 75dB if it’s fanless?
A: The miner itself is fanless and silent. The 75dB rating accounts for the ambient noise generated by the external support infrastructure of an immersion farm, such as fluid circulation pumps and cooling towers.
Q: Is the improved efficiency of the M76S worth the investment?
A: Yes, for serious operations. The jump to 13.5 J/TH represents a significant reduction in your largest variable cost (electricity). For large-scale or continuous operations, this efficiency gain directly increases profitability and shortens the payback period on your hardware investment.
The WhatsMiner M76S is the strategic choice for miners who understand that true competitiveness lies in optimizing both output and efficiency. Step beyond the standard and equip your immersion operation with the enhanced performance and superior economics of the M76S. Build a denser, more profitable, and more sustainable mining future.
