In detail
- Design switches to 100% liquid cooling; heat is captured at the chip and carried through high‑temperature liquid loops.
- Servers are run hotter — up to 45 °C (113 °F) — to allow outdoor dry coolers to reject heat efficiently.
- Nvidia cites reducing water use from roughly 2.6 million gallons per megawatt per year for conventional cooling‑tower systems to near zero, per sustainability head Josh Parker.
Why it matters
Liquid cooling can materially lower water use and improve thermal efficiency for AI data centers, but it doesn’t remove construction‑phase impacts or power‑generation needs and may raise build costs.
For you When planning or procuring compute, ask providers for cooling approach, water‑use metrics and cost comparisons; consider liquid cooling for long‑term large‑scale deployments.
