It isn't really much of an issue but my computer hums, up till now i just thought it the PSU or Case fans (its a fan like noise) but as tonight im going to be sleeping with it next to my ear again for a d/l I thought lets try and find out what dam component wakes me up! So I: Stopped PSU fan, no effect Unplugged case fans, no effect Turned right down water cooling fan, no effect (its not this btw as this is out of the case) Stopped GPU fan, no effect I then listened to the HD the water pump and the dvd drives and each produced a peticular very quiet sound. So I've ruled out every single component in my computer! The sound seems to eminate from everywhere inside the box! Anyone hazard a guess at what it is?
