45°C cooling design cuts data center water use to near zero

NVIDIA's new Rubin generation AI servers use 100% liquid cooling operating at 45°C, enabling data centers to dramatically reduce energy and water consumption by eliminating traditional air-cooling infrastructure. This approach can cut cooling water usage from 2.6 million gallons per megawatt annually to near zero while saving a 50-megawatt facility over $4 million annually in cooling-related costs, since cooling historically accounts for up to 40% of data center electricity consumption.
