Dumb question, but is this done with fresh water?

If so, why?

If not, does it matter how much water is used?

Its freshwater and has to be freshwater because it goes through pipes and/or is evaporated. Corrosion, scaling and fouling are all issues.

Even if seawater was easy to use and datacenters were near the shore, it would produce very saline brine which would be difficult to safely get rid of.
