It’s very odd when mainframes (S/3x0, Cray, yadda yadda) have been extensively water-cooled for over 50 years, and super-dense HPC data centers have used liquid cooling for at least 20, to hear Google-scale data center design compared to PC hobbyist rigs. Selective amnesia + laughably off-target point of comparison.

Hasn't this just been for things like rack doors and such?

In the last ~two generations of servers it seems like now there's finally DLC (direct liquid cooling) into the actual servers themselves (similar to the article). Intel kind of forced that one on us, with their high-end SKUs. This has been a pain becuase it doesn't fit into legacy datacenters as easily as the door/rack-based systems.

I won't say which server vendor it is, but I've put in more than one service ticket for leaking coolant bags (they hang them on the racks).
