Edit - I switched to an Msi Unify and it has the same issue with coil whine from the vrm and noise from the ssd
Here’s a video recording of the coil whine on my X570 master. This is whilst the system is idle, straight after logging into windows, using the ryzen balanced power mode. For the purpose of the video I unplugged all fans (no heavy load on cpu), so you can hear it clearly.
On intel systems we can disable cstates to quieten the noise, yet I’ve tried toggling many options in the aorus X570 bios - to no avail, including cool and quiet, vrm frequency, spread spectrum and c-state.
It seems to resonate throughout the whole board, no matter where I hold the microphone. The recording was done on an iPhone 8 with built in mic and has not been edited / amplified.
When I scroll webpages the noise makes a grinding sound.
I resorted to placing acoustic foam around my hard drives as they are chirping and are making high pitch sounds - which I never knew was possible until I got the aorus master.
Some people claim they may not hear it but if you built your system in a quiet room / with quietness in mind, it can become annoying.
Chipset fan : silent (off)
Hard drives connected : 2 x ssd
Graphics card : fans turned off
Power supply : tried two power supplies, Corsair rm 850 and rm 850x (no difference to the coil whine)
