NVIDIA’s newest AI servers can run their cooling liquid even hotter — up to 45 degrees Celsius, or 113 degrees Fahrenheit. That higher temperature limit is precisely what makes them more energy efficient. The Rubin generation of NVIDIA AI infrastructure is the world’s first to achieve 100% liquid cooling — every chip, every networking component, cooled entirely by liquid in a closed loop with no fans anywhere in the system. This liquid cooling methodology is outlined in the NVIDIA DSX AI factory reference design, a guide that outlines best practices to design, build and operate the entire AI factory infrastructure stack. Although each generation offers significantly more computing power for each watt, full liquid-cooled AI compute infrastructure enables data centers to dramatically reduce cooling energy consumption — making a meaningful difference to overall data center energy use at hyperscale. “The NVIDIA DSX reference design for AI factories has zero water..."},"evidence_pages":[],"related_signals":[{"id":"eba38c3c-beaf-43b8-8296-eb410f43070d","url":"https://onlylabs.fyi/signals/eba38c3c-beaf-43b8-8296-eb410f43070d","source_url":"https://blogs.nvidia.com/blog/geforce-now-thursday-steam-summer-sale-2026/","title":"The Ultimate Summer Sale Pairing: Steam Sale Meets GeForce NOW Discounts","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-25T13:00:34+00:00","first_seen_at":"2026-06-25T16:01:22.607026+00:00","date_source":"rss.item_date"},{"id":"c2506dde-f3e5-4708-80a8-6f267c8a2190","url":"https://onlylabs.fyi/signals/c2506dde-f3e5-4708-80a8-6f267c8a2190","source_url":"https://blogs.nvidia.com/blog/nvidia-aws-ai-production-scale/","title":"NVIDIA and AWS Collaborate to Bring AI to Production at Scale","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-24T00:05:37+00:00","first_seen_at":"2026-06-24T04:00:27.840443+00:00","date_source":"rss.item_date"},{"id":"3d9fe518-9208-46b1-aa74-e97182de6b01","url":"https://onlylabs.fyi/signals/3d9fe518-9208-46b1-aa74-e97182de6b01","source_url":"https://blogs.nvidia.com/blog/nvidia-agent-toolkit-open-models-tools-skills-secure-runtime-ai-agents/","title":"How Businesses Are Building Specialized AI They Can Trust","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-23T13:00:07+00:00","first_seen_at":"2026-06-23T16:00:26.969295+00:00","date_source":"rss.item_date"},{"id":"4c3c8bdd-4757-49d0-a9aa-76aef71b4d41","url":"https://onlylabs.fyi/signals/4c3c8bdd-4757-49d0-a9aa-76aef71b4d41","source_url":"https://blogs.nvidia.com/blog/top500-green500-supercomputers-isc-2026/","title":"NVIDIA Powers Over 400 of the World’s 500 Fastest Supercomputers","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-23T09:00:38+00:00","first_seen_at":"2026-06-23T12:01:19.712727+00:00","date_source":"rss.item_date"},{"id":"39d555b5-10b5-45d7-adb5-a3ea3fe73756","url":"https://onlylabs.fyi/signals/39d555b5-10b5-45d7-adb5-a3ea3fe73756","source_url":"https://blogs.nvidia.com/blog/telecom-ai-agents-dtw-ignite-2026/","title":"NVIDIA Brings Trusted, 24/7 AI Agents to Telecom Operations","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-23T06:00:09+00:00","first_seen_at":"2026-06-23T07:00:31.458708+00:00","date_source":"rss.item_date"},{"id":"1d360d2e-11df-44b1-9371-ca5f2cf2cf86","url":"https://onlylabs.fyi/signals/1d360d2e-11df-44b1-9371-ca5f2cf2cf86","source_url":"https://blogs.nvidia.com/blog/jupiter-exascale-supercomputing-science/","title":"At ISC, JUPITER Shows What Exascale Science Looks Like","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-06-22T13:00:48+00:00","first_seen_at":"2026-06-22T16:00:28.17608+00:00","date_source":"rss.item_date"}]}
