NVIDIA describes 45C warm-water cooling to cut data center water use

Summary: An NVIDIA post (200 points) describes a liquid-cooling design for AI data centers that uses 45C supply water, which it says removes the need for evaporative cooling and cuts on-site water use to near zero. The figures are NVIDIA's and presented as design claims for its reference AI-factory cooling.
Why it matters: Water consumption and cooling design are becoming operational and siting constraints for large GPU clusters, so warm-water direct-to-chip approaches matter for where and how AI capacity is built.
Follow-up: None.
