Hello!
I just got woken by a horrible noise from my computer, yep, it woke me up from sleep - it's that bad. At first I though my hdd was failing since the sound didn't come back until steam began updating games wich mostly are on my hdd. But then I opened the case and couldn't tell if it was my cpu-pump or the hdd.

Any help at all would be appriciated!
edit: apparently watching videos intensifies the sound
edit2: Played some star wars battlefront which is on one of my ssd:s and the sound disappeared and I just heard normal fan sounds - it has yet to reappear for some reason...
edit3: It's back but somewhat quiter
edit4: Watching videos on youtube seem to make it go louder
Found the problem: One of my gpu-fans seem to make the noise isnce it stops when I stop that particular fan. It may be loose so that it only sound for a certain interval of rpm?
