A. Executive Summary
The rapid proliferation of artificial intelligence has transformed the data center industry in ways few anticipated even five years ago. Where legacy server farms once managed workloads of 5 to 10 kilowatts per rack, modern AI training clusters now routinely demand 50 to 135 kilowatts per rack, with next-generation architectures projected to reach 600 kilowatts or more. This exponential increase in thermal output has shattered the assumptions underlying traditional air-cooled infrastructure and ignited an urgent, industry-wide race to reinvent how computational heat is managed, removed, and, increasingly, repurposed.
This report synthesizes findings drawn from industry analyses, academic peer-reviewed literature, governmental agency reports, regulatory filings, and engineering standards to provide a comprehensive picture of the current state of AI data center cooling. The report examines …
