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.

Traditional data centers cool hot chips the way a swamp cooler works, by evaporating enormous amounts of water—often millions of gallons a year for a single large facility. As AI compute scales, so does that water demand, creating both environmental and public-relations problems. NVIDIA's alternative cools chips with liquid rather than air,
