Nvidia is making a sweeping claim: the water problem plaguing AI data centers is basically handled. A top executive at the company says its next generation of AI infrastructure can largely address the growing concerns around water consumption that have dogged the industry for years.
The tech behind the claim
At the heart of Nvidia’s pitch is a shift from traditional air cooling to warm-water direct-to-chip liquid cooling. The company’s GB200 NVL72 rack-scale system, part of the Blackwell platform, uses full liquid cooling that Nvidia says achieves 300x water efficiency compared to conventional air-cooled architectures.
The upcoming Vera Rubin platform pushes this further. It’s designed to operate with inlet water temperatures up to 45°C, which is about 113°F. That’s warm enough that data centers running these systems wouldn’t need the massive industrial chillers that traditionally gulp down enormous volumes of water and electricity.
Data center cooling can account for 30% to 40% of a facility’s total energy consumption. Nvidia claims its Blackwell systems deliver energy efficiency gains of 25x to 30x over previous generations.
