They typically don't. The servers are air cooled and the room is conditioned with a Liebert or similar HVAC system. Liquid cooling servers is not practical or warranted for most situations.
That's not entirely true, some do in fact use water cooling. There's even "of the shelf" solutions from Supermicro.

It's not widespread, but it's not inexistent.
Expanding on that, direct water cooling becomes more common the higher power density the racks are.
So as you get into 35kW+ racks it becomes the only way to get that much heat out, lots of GPU compute racks are water cooled by default now, the El Capitan super computer is entirely cooled through direct liquid interfaces, for example.
