By switching to 100 percent liquid cooling and running servers hotter, Nvidia claims it can cut water use to “near zero.”

Public pushback against data centers has emphasized their water and energy consumption, and now Nvidia is highlighting its claim that the Rubin generation reference design for a fully liquid-cooled data center has “eliminated massive amounts of power usage and pretty much all water usage.” Still, it doesn’t address all of the concerns around AI data centers, including during their construction, and for the power generation requirements of the massive facilities. Also, as Gizmodo points out, Nvidia’s blog post doesn’t mention the cost of building this style of data center vs. one using less efficient air cooling, but claims that “every cloud provider and data center operator building for [Rubin] is making the transition.”
