Immersion Cooling System: Must be installed in a compatible immersion mining tank with dielectric fluid, pumps, and heat exchangers.
Industrial Power Supply: Requires stable three-phase AC 380-480V power with proper circuit protection.
Tank Integration & Layout: Designed for submersion; planning for spacing and fluid flow is crucial.
Network Connectivity: Utilizes Ethernet via waterproof pass-through connections within the tank.
Use Compatible Dielectric Fluid: Always use high-quality fluid specified for ASIC immersion cooling.
Ensure Proper System Cooling: The external cooling loop must have adequate capacity to handle the thermal load.
Leverage Easy Maintenance Access: Utilize the design features to perform regular checks and fluid monitoring efficiently.
Professional Installation Recommended: Deployment into immersion systems should be handled by qualified technicians.
Q: What is the main advantage of the M78’s immersion cooling?
A: The primary advantage is superior thermal management. It ensures consistent temperatures, which leads to stable hash rates, longer hardware life, and much quieter operation compared to loud, dust-prone air-cooled systems.
Q: Is this miner suitable for a beginner or a small home setup?
A: No. The WhatsMiner M78 is a professional, immersion-cooled unit that requires a significant infrastructure investment (immersion tanks, cooling systems). It is designed for professional mining farms and large-scale operations.
Q: What does “modular deployment” mean for this miner?
A: It means the miner is designed to be a standard building block that can be easily integrated and stacked within a larger immersion cooling system, allowing you to scale your hash power seamlessly by adding more identical units.
Q: Can I run the M78 without an immersion cooling tank?
A: Absolutely not. The M78 is an immersion-cooled (oil-cooled) ASIC miner. Operating it outside of its intended dielectric fluid bath will cause immediate overheating and permanent, irreparable damage.
Q: How does the 14.5 J/TH efficiency benefit my mining operation?
A: This efficiency rating means you use 14.5 joules of energy to produce one terahash. A lower J/TH value is better. This directly reduces your electricity cost per Bitcoin mined, which is crucial for maintaining profitability, especially as network difficulty increases.
The WhatsMiner M78 is engineered for miners who are building the future of Bitcoin mining today. By combining reliable high performance with the proven benefits of immersion cooling, it offers a sustainable and efficient path to scale. Choose the M78 for a foundation of stability, efficiency, and professional-grade performance in your mining operation.
