Is there such a thing as a rackmount water cooler?

[Thunderdolt]

I'm considering water cooling the office's collection of GPUs and moving them to a rack. The latter basically drives the former due to form factor limitations: desktop cards drop to only 2-slot width when the 3-slot air cooler is replaced with a water block, and you can fit 10x2-slot cards into 4U vs only 6x3-slot cards.

To manage that heat dump (~6kW), I'd need a pretty large collection of radiators. Before I go off and make my own, I figured I'd check to see if something like what I want already exists. Is there something out there which has a bank of radiators with >=6kW capacity plus a couple of pumps, and which fits into maybe 10U or even 20U of space?

could look into chiller units...

Koolance used to make things like your asking for back in the day.

Interesting. Will take a look at that. Looks like they're getting the 4500W of capacity by running the coolant very hot (25C over ambient), so the capacity is likely closer to 700-1000W when coolant is kept to safer limits.

You could run more than one of them... You could also incorporate https://koolance.com/cooling-systems-liquid-to-vapor-chiller A friend of mine heats his apartment with a 24u rack partly filled with the thing Enigma linked and the koolance 900w chiller.
