Nvidia unveils high‑temp liquid cooling to slash AI data‑center water use

AI data‑centres consume vast amounts of water, with projections for 2025 indicating usage comparable to a small nation’s bottled‑water production. Nvidia has introduced a closed‑loop cooling system that circulates a water‑propylene glycol mixture at temperatures up to 45‑46 °C, allowing servers to be cooled without the large‑scale water‑intake of traditional chillers.

The company claims the new approach could "rozwiązać problem ogromnej konsumpcji wody" and lessen the need for external cooling equipment. Adoption is expected to be gradual, as data‑centre operators weigh the initial cost against long‑term water‑saving benefits. As one commentator noted, the servers are now “chłodzone już tylko 'wrzątkiem'”, highlighting the shift to high‑temperature liquid cooling.

While the technology promises a substantial reduction in water use, its impact will depend on how quickly the industry embraces the system and integrates it into existing infrastructure.
