My PC is making a high pitched noise (like coil whine) only under Linux (piefed.social)

So I built a new PC a couple weeks ago. My old one broke one day (I think I helped it, but that's another story). I was happy to move from a stock Prism Wraith cooler that was LOUD and ANNOYING. I put a new AMD Ryzen 9 7900X in this box with a couple of new nvme drives (Samsung 9100 PRO and 990 PRO). The thing is silent under Windows 11. Silence at last!

Then I installed openSUSE Tumbleweed (from which I'm typing this) and as the post title says, something is making a high-pitched noise, like coil whine, when the system is mostly idle. I searched the web and the first suggestion is that Linux handles CPU power states (C-state) differently than Windows. Or, it could be the new disk(s), too. It's a fly in the ointment, I am very happy with the new PC, with how powerful and fast it is, I'm so far happy with openSUSE, but there HAD TO be SOMETHING to spoil the experience.

Has anybody had a similar problem? Any tips on how to troubleshoot it and not BREAK my computer?

In my case, the GPU was responsible for some coil whine, but only when playing games or running LLMs. Try booting from a live USB with a different desktop environment (kde or gnome) or one that doesn't use GPU acceleration (like xfce, lxde or mate).

If the issue disappears in another environment, it's likely related to the GPU and how the DE uses it.

It might also be other components, so it would be very helpful if you can run the pc while it's open and hear where it's coming from.

I didn't list it, but I don't have a dedicated GPU. I just use the Ryzen iGPU. This is a work machine, it's all I need.
