I've been considering moving to the Z390 platform, but I've read a fair few posts and user reviews complaining about VRM coil whine. A wide range of manufacturers and models are mentioned (particularly Gigabyte Aorus and lower/mid Asus). Is this genuinely wide spread or are these people just unlucky? I'd never heard of coil whine on a motherboard before. I've experienced coil whine from the GPU at load, but at least you can drown it out in games. Putting up with it when I'm doing basic work would drive me to distraction and puts me off forking out a reasonable sum for an upgrade. I've read some people have had various degrees of success disabling C-states, but that doesn't seem like a very elegant solution (and shouldn't be necessary). Thanks for your thoughts.
