As rack densities climb into the AI era, liquid cooling is moving from niche deployment to mainstream consideration but real-world implementation remains complex. Questions around architecture selection, serviceability, facility integration, and long-term operations are now front-of-mind for many operators. This session will examine the current state of liquid cooling adoption, focusing on practical deployment experience rather than theory. Participants will discuss where liquid is delivering measurable value, where integration friction persists, and how teams are preparing facilities and operations for sustained high-density environments.
