Relevant.

OVH has been using liquid cooling for many years:

And yet their claimed PUE is 1.26 which is pretty bad. One way to characterize that overall PUE figure is they waste 3x as much on overhead as Google (claimed 1.09 global PUE) or Meta (1.08).

10 years ago, OVH datacenter SBG1 was below 1.1 with a mixture of natural convection + liquid cooling. But I have not been following in the latest years.
