Fanless Liquid Cooling for AI Servers

CoolIT, an Ecolab company, argues that AI server racks beyond 250 kW can no longer be cooled effectively by hybrid liquid-and-air approaches. At such densities, a 70/30 liquid-air split still leaves roughly 75 kW of air load, adding cost and complexity. The article promotes fanless, 100% heat-capture liquid cooling for next-generation AI factories. As AI infrastructure scales, power and cooling constraints are becoming central to where and how data centers can be built. The pitch reflects a broader industry shift toward direct liquid cooling, immersion, and other high-density thermal solutions to support increasingly power-hungry accelerators.
