Hey everyone,

I'm planning a custom watercooling loop for a Lian Li O11 Dynamic Mini V2 and would love a sanity check on my parts list before I order.

The concept: hybrid dual-chamber design

To get the best of both worlds, I'm splitting the loop into two zones:

• Main chamber (visible through glass): Clean 14mm PETG hardtubing for the CPU block, radiator, and pass-through.
• Rear chamber (hidden behind the panel): Flexible 10/16mm PVC softtubing connecting to the DDC pump.
• Pump placement: The DDC pump/res combo sits in the rear chamber, next to the PSU/drive area.
• The pass-through: A G1/4" female-to-female extender links a 14mm hardtube fitting in front to a 10/16mm softtube fitting in back.

Why hybrid? It keeps the front pristine, absorbs DDC pump vibration, and avoids nasty bends in the cramped rear chamber.

Good afternoon

I have a 2.5-inch SSD and two 3.5-inch HDDs installed in an old Dell Optiplex. Since the server has an SFF form factor, I had to place the HDDs directly in front of the single intake fan. I've been wanting to upgrade the CPU and RAM in my gaming PC for a long time, from a 5600G and 16GB to a 5800X3D and 32GB. So I thought, why not treat myself to the upgrade, use the old CPU and RAM, buy a new motherboard, a better case, more fans, and a power supply, and upgrade my server that way? However, I've watched a lot of server videos by 'WolfgangsChannel' on YouTube, and he always mentions something about an "AMD Idle Freeze Bug on Linux" or something similar when discussing AMD builds.

Now my actual question: What is this "AMD Idle Freeze Bug on Linux"?

Is there anything I can do about it? Are AMD CPUs therefore unsuitable for servers?

Thank you in advance to everyone who has read through this incredibly long text before replying, so I can take the time to look at my problem.
