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?

    That is awesome! I had no idea swamp coolers could cool that well. The one in my shop can barely drop the temp 10-15 degrees below outside (on a good day). Sorry for doubting you, so used to people outside of arid climates not knowing what a swamp cooler is.

      10-15 degrees is all you need to keep a “cold aisle” at 85degf, most places, on the worst day.

      IIRC Amazon figured out that individual components could actually run hotter within an acceptable replacement window.

      higher equipment replacement is more than offset by the fact they don’t have to do refrigerant based cooling which makes daily operation ridiculously cheap… no pumps or complicated mechanical devices to produce cooling… no people with special skills to maintain them, etc.

        That 10-15 (in my case) relies on no extra heat. When I have game nights it gets pretty toasty inside with 5 or so extra bodies in the shop.

        My last experience with a server room was in 2002 or 2003, and the rooms were kept in the mid to low 60s.

          no doubt.

          I remember when you’d put a jacket on before you went in the halls… but now everyone wears shorts.
