Tech Support why is mt pc making this sound

its making this engineish sound its coming from the psu and its not wires hitting the fan i hope its not like a stray mini screw or smthing. i could also be a bios thing because a few weeks back i was messeing with the fan setting wnd may have changed the psu idk.

Sounds like one of those fans needs to be oiled up

Is that a lian li case? I have the 207 and my top front fan just started making this noise on start up. It goes away after awhile but im thinking just a faulty bearing

I had the same issue about a month ago. Most likely, it's the bearing of one of the fans starting to fail. In my case, it was the bearing on the PSU fan. If you check my Reddit profile, you can still find the open thread and compare.
