I suspect the big ones use evaporative cooling because they’re trying to build in the gigawatt scale and IIRC there was talk about single racks reaching a megawatt soon, currently they’re ~150 kW.
The power density of those new nVIdia GPU compute servers is nuts and using evaporative cooling means less energy use than closed loop.
What I’m saying is, some of those planned datacenters wouldn’t be feasible with closed-loop water cooling. And yes, I agree with you that this should be legislated. If they can’t cool their servers without evaporating a bunch of drinking water, they can… have fewer servers.
What’s the power scale of yours?
