Liquid Cooling
Direct-to-chip or rack-level liquid cooling; now standard for AI data centers above roughly 50kW per rack.
Liquid Cooling circulates coolant directly to chips or across the rack to remove heat that air cooling cannot handle. It has become standard for AI data centers above roughly 50kW per rack, where GPU density makes air cooling physically inadequate. The shift to liquid cooling is a structural change in data-center design that benefits a specific set of thermal-management suppliers. See Cooling 101.
