Fanless liquid cooling reaches 250kW+ rack limits, shifting thermal design

SO WHAT
Thermal throughput becomes a gating variable in the phase transition: the old cooling stack can’t scale, so compute supply tightens around players with capital, tooling, and system integration leverage.
Above 250kW per server rack, hybrid liquid-air cooling leaves too much air heat load. CoolIT claims fanless capture can avoid expensive, complex air-moving systems operators won’t accept.
