Question Motherboard coil whine

[Kerygam]

Dear Gaming community!

I just built a new pc, and unfortunately something happened that I am not very happy about: Coil whine (Or something like that) Videos:

The noise around the CPU only occurs when the GPU is under load. (barely noticable in idle) And.. its not about the FPS (I read it on other forums that if you lock your fps its gonna be quieter)
For example, the coil whine noticable when:
League 200+ fps
COD MW: 60+ fps
Valorant 200+ fps
Subnautica Below Zero: Even in the menu, and same at every FPS
Fall Guys (Menu, and 140+fps)

It cannot be the GPU, because I tried with another one, and its the same, and the noise is obviously coming from around the CPU. (Maybe VRMs?) I read so many articles about this but I have no idea what to do.
What I tried:
- Checking the fans to see they causing the noise (nope, sadly, they are too quiet, thats why the whine is even worse)
- Disabling Power saving mode/C-state in bios

• Downgrading the BIOS to older versions
• Disabling XMP
• Changing the maximum CPU state to 99% instead of 100% in the power saving options (Idk about that one)

The config:
MOBO: ASUS TUF GAMING B560M-PLUS
CPU: i5-11400f
Cooler: Arctic Freezer 34 eSports duo
RAM: 2x8GB G.skill Aegis 3200
SSD: Samsung EVO 980 PRO 500GB
GPU: GTX 1650
PSU: SEASONIC CORE GM 650W 80+ GOLD MODULAR (SSR-650LM)
OS: Windows 11 Pro

What can you recommend I try or do to reduce the noise? I have very sensitive ears, that's why it bothers me so much. The other strange thing I noticed that some rubber adheasive pads fall off the motherboard somehow, and I dont know from where, but I found them on the bottom of my case. (I found 3) something like that: https://i.ebayimg.com/images/g/bf4AAOSwLVZVsLcs/s-l400.jpg

Contact your retailer. It's a new board and you've gone to great enough lengths trying to solve the problem yourself. I'd send it back if they will let you.

could be that a new motherboard will be louder than this one, I doubt that you will stop the sound by replacing it with identical hardware.

you can try this setting in BIOS:
acoustic noise mitigation

Thanks for the suggestion!
Sadly the mentioned BIOS setting does not help.
