HR 5332 United States House · 119th Congress

Liquid Cooling for AI Act of 2025

This bill (HR 5332) mandates a federal review of liquid cooling technologies for data centers, requiring the Government Accountability Office (GAO) to assess their research needs, costs, benefits, and market adoption within 90 days. The study will evaluate how liquid cooling compares to air cooling for efficiency, safety, and heat reuse, including waste heat capture for secondary uses. It directly affects federal agencies operating data centers (like the Department of Energy) by informing future infrastructure decisions. The GAO report and subsequent Department of Energy assessment will guide potential policy but do not fund or require adoption of liquid cooling.
