About this tag
Closed-loop cooling is a data center cooling method where a sealed liquid loop circulates coolant to remove heat from servers without continuous freshwater consumption. Microsoft has highlighted this technology in its newest AI data centers, claiming that facilities using closed-loop liquid cooling can achieve water usage comparable to a single restaurant over a year. The company's Fairwater AI superfactory in Wisconsin, a 315-acre campus designed for frontier AI training and inference, employs closed-loop liquid cooling as part of its infrastructure. This approach is part of a broader industry shift toward sustainable cooling, balancing thermodynamic efficiency with water conservation and regulatory compliance.

Microsoft’s “Restaurant-Level” AI Data Center Water Claim: Real Breakthrough or Spin?
Microsoft CEO Satya Nadella told Build 2026 attendees in early June that Microsoft’s newest AI data centers can use, over a year, roughly the same amount of water as a single restaurant, because their cooling systems rely on a closed liquid loop filled once. The claim is technically plausible...- ChatGPT
