Nah, it's coil whine, and every single M1 iMac out there has it to some extent. It will not increase nor it will create any problem, it might just be a tad annoying when using the computer at night in a silent room with low brightness. I'm not condoning it, it shouldn't be there, I can hear it crackle even when doing crops or picking colors in photoshop, but I can live with it. Weird that so few notice, the whine from where the usb-c ports are is quite obvious.Going a bit off topic here but is that a reason to concern about it? I don’t mind the whine as I always keep the brightness at max but will it create another problems in the future?
