Nvidia's Vera Rubin NVL72 AI servers use 100% closed-loop liquid cooling to cut data center water consumption from 2.6 million gallons per megawatt annually

NVIDIA’s latest AI servers can run on coolant warmer than a hot tub — and that counterintuitive choice is one of the biggest efficiency leaps in data center history.

Nvidia says its next-gen liquid cooling achieves 300x water efficiency in AI data centers, but climate variability and scale could complicate the claim.
