    So I've been the owner of a Corsair HX620w for what seems like forever, 10years maybe? and it's always been faithful. I've been rejigging my case around in aid to quiet her down and with the newest fans I've put in (which are very quiet) I can hear an audible coil whine (I guess). It starts after about 30seconds of booting in to windows and is then present all the time. It's really quiet, and I guess with the silent fans I've now got that's why I can hear it over the top so it may have been going on for a lot longer? Or could it be the sign of my PSU failing. It also spikes a bit louder with what seems like mouse movement, I've a Logitech G Pro and not noticed it before with prev fans in the system. The linked youtube vid is exactly what I'm hearing albeit not quiet as loud, from about 14seconds that noise is spot on.


    Rest of system if it makes a difference is MSI Z77 Mobo, i5-3570K, 16Gb ram and KFA2 GTX970. 3x HDDs 1x SSD. 4 system fans.
