Google’s Brazos: Rack-Mounted Liquid Cooling for Air-Cooled Data Centers

Next-generation AI and HPC chips routinely exceed 1000 W TDP, pushing well beyond what standard air cooling can handle.

Retrofitting entire data center facilities with chilled water loops requires massive capital and months of downtime, creating a real tension between the need for high-density compute and the operational reality of existing air-cooled infrastructure.

Google‘s Brazos system directly addresses this gap.
