Hotter Than a Hot Tub: The 45°C Breakthrough to Cool AI’s Biggest Machines
45°C. That's the temperature threshold NVIDIA just cracked to cut AI data center cooling costs by double digits.
The KeyNews take
Why it matters
NVIDIA's higher-temperature liquid cooling breakthrough directly reduces operational expenditure and power consumption for AI infrastructure—a critical lever for cost competitiveness as compute demands scale. This is a material efficiency play that affects every large-scale AI deployment's unit economics.
The key facts
4 to knowNVIDIA servers now support 45°C (113°F) liquid cooling vs. previous lower thresholds

Publisher excerpt: Hot tubs sit at about 38 to 40 degrees Celsius, warm enough that most people can only soak for about 15 minutes. 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…
