NVIDIA has proposed a liquid-cooling design for AI data centers that it says can eliminate virtually all on-site water consumption for chip cooling, replacing traditional evaporative cooling with a sealed warm-liquid loop that rejects heat directly to ambient air. The design, detailed on its official blog, recirculates the same coolant in a closed loop, cutting on-site water use from millions of gallons per facility to near zero.
Key facts
What: A new NVIDIA cooling design claims to use almost no water inside the data center, though critics say that's only part of AI's water bill.
