Re: coil-whining z690 Classified (due to mouse movement)
A few things...
General EM/EFI refreshes can sound like coil-whine but it's not....
Check your speakers (unplug them/power them off), turn off your monitor and then move your mouse. Still hear it? Maybe you're on to something. I hear something similar on occasion, but it comes out my speakers, and even better yet, I have a wireless mouse. Also depends on what's on my screen - high levels of white or black seems to do it more. It's also worse when I use my aux-in on my speakers from a docking station for my work laptop, to which I share my monitor between them when I am working from home.
Oddly, some games will give me actual coil whine from my GPU while others will not - Elden Ring, for example, no whine. Mechwarrior Online does it at LVL99!
