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?

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.
