Hi, I’m building a homelab watercooled unix server. I don’t want to buy expensive overpriced pre-mixes from ekwb or aquatuning. What cooling solution do datacenters use for water cooling?
What is the chemical solution? Does anyone know?
There’s no way you need whatever you’re looking for.
What cooling solution do datacenters use for water cooling?
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.
is liquid
cookingcooling really necessary? critical data centers I have worked in use swamp coolers. cheaper, more efficient, more reliable, uses same water as your house…edit: d’oh! :)
liquid cooking?
Haha, stupid sexy autocorrect, or honest typo, either way I got a good chuckle!
oh man! I just poked ptsf@lemmy.world for a Austria!=Australia flub in another thread… my come uppins!
The cooler is made of lava 🔥
Haha, carry on 👍
In ours, the coolant is referred to as “PG25” (distilled water with 25% propylene glycol, plus corrosion inhibitors and other additives). It’s widely available, and pre-mixed so it just gets poured straight in.
Your problem is going to be quantity. it might be cheaper per unit, but buying less than a 200 litre drum (if not a 1000 litre IBC) will prove to be a challenge.
I’d suggest a rethink, honestly.
Water cooling is typically much more complex and expensive than air cooling, and is mainly attractive because of space limitations. The same applies to data centers. IBM’s mainframes have a liquid cooled version mainly targeted towards users wishing to get the most out of their data center space before upgrading sites. These ship without coolant, and simply ask the user to “just add water,” i.e. just demineralised/distilled water.

I have no idea what a data center would use and I haven’t over locked since the 90s, but water wetter is what I used then.
