Full Rack Cooling

Hey there,
I'm looking for a way to improve cooling for my rack. r/n I got 4 systems running in an APC SX AR3140 :
  1. Workstation
    1. AMD Ryzen 5950X (OC) / RTX 4080 (OC) / 128 GB RAM / will mostlikely be replaced by end of year and used as an AI Server
  2. Servers
    1. Vir1: AMD EPYC 7551P / 256 GB RAM
    2. Vir2: AMD EPYC 7551P / 256 GB RAM
    3. Gateway: AMD Ryzen 5 4500G / 32 GB RAM
  3. Network
    1. Unifi Dream Machine
    2. Unifi Usw Aggregation Switch
    3. Unifi Enterprise 24 Port PoE Switch
  4. Additional
    1. Mac MIni Server (2012)
    2. Mac Mini Server (2012)
    3. ISP Router
    4. 10 Raspberry Pi 4
So first thought would be more Airflow...now this is a lab system in my office and it is getting toasty while I do not really want to install an AC.
Not all systems are constantly running. Especially the two virtualization servers are only running when I am playing around with k8s/rancher and similar products.
I am a huge fan of watercooling. My workstation is partially watercooled but in the end everything gets too hot. I already added an APC ACF504 fan insert and it helped but when everything is running my office gets 10 degrees celsius (50F) warmer than the rest of my flat.

Second thought:

Any ideas for my systems?

best regards and thanks in advance

A chiller is anything but quiet. If it's in the office where you work, it will be unpleasant.
I also don't understand exactly what you want to cool from the systems listed? So which system do you have which problem with exactly?
And what kind of server case are you using? What is the internal structure?
There is very little information here.

Hi Eddy,
Thanks for the information about the chiller - i didn't know that.
Groups 1&2 would be candidates for cooling. My workstation itself runs okay as long as no system from group two is running under load.
My workstation resides in a silverstone RM52 and the rest in some off brand enclosures. Virt servers use supermicro boards and are cooled with Noctua NH-U9s at the moment.
Watercooling would enable me to add some more systems and use alphacool cases.

Hi,
You will want to set up the first system with the 4080 again either way. I would then switch directly to one of our cases, as it is then relatively easy to install a water cooling system in it.
With the two virtual servers.... it would be helpful to see a picture of the inside to see what would fit in there. These are not CPUs that have a lot of waste heat. It's just a question of how to fit in the reserve/pump and the radiators. But without seeing the systems directly, I can't say much.

I simply wouldn't go for the chiller in the systems. That would end up being more complicated and also more expensive.

The housing does not offer much space. One possibility would be to screw a dual 80mm radiator onto the back. In other words, a fan on the case and then the radiator with the correct PCIe slot connection position. And then connect the whole thing to an Eisbaer Pro. The Eisbaer Pro is a CPU cooler, reservoir and pump in one. That could work well.

Then just add 4 connections, a hose (EPDM or TPV not PVC) and coolant, and you're done.
