Nvidia says its AI data center design runs hotter to use a lot less water

Nvidia has unveiled its Rubin generation reference design for fully liquid-cooled data centers, claiming it can reduce water consumption to nearly zero by operating servers at higher temperatures, up to 113°F (45°C). This design reportedly eliminates significant power usage and virtually all water use, addressing public concerns about the environmental impact of data centers. However, Nvidia has not disclosed the cost differences between this and traditional air-cooled systems. The company emphasizes that every cloud provider transitioning to this design is making strides towards sustainability.
