  • Loud noise coming from PSU fan

    It's kind of a tickling sound. Sounds ugly when I shut down the computer.

    [edit] what a boring topic to post my 7000th post with.

    If it's really the PSU fan ticking (and not the HDD, which is a common sign of impending HDD doom), then it means either:
    a) You have something stuck in the fan, like a grain of sand or a wire or something (presumably external?)
    b) Your fan is misaligned and the fan blade is hitting the grating or something else

    Air duster can solve A) (plus a visual inspection). B) is harder to solve.

      It's definitely the PSU. On the bright side, it also seems like the fan is rotating at normal speed (couldn't discern individual blades) so I figure it isn't dying. Maybe I'll just bear with it and hope it goes away on its own.

        Air dust. If that doesn't solve it, I would guess the bearing is failing. Look for a new PSU. If the fan goes kaput, the PSU could overheat fast and potentially cause more expensive problems.
        To us, it is the BEAST.

          Definitely replace the PSU if you can't fix it; $50 is way cheaper than [new system].

            I had another look I couldn't spot anything hitting the fan. It also seems be rotating normally, only rattling at it.

              The bearing (in most cases it's just a bushing) in most case and psu fans isn't of the highest quality, and as soon as it's a little bit off, it causes vibrations in the fan. Usually, the fan will last in working order for a long time before it fails, (if you can stand the noise, that is) and sometimes it goes away on its own (not for long though).

              You can change the fan if it's a particularly good PSU if you don't want to change it just yet, or take it apart and lubricate the bushing (use something heavier than WD-40 though).

              In any case, an overheating (modern) PSU will very rarely damage your PC. Of course, you might not want to risk it for just a few dollars

                Well yeah, it's 650W PSU that cost me €90. Does noise typically fall under warranty?

                  I live in the third world, what is this 'warranty' thing you speak of? Check with the manufacturer, but it should, I think.

                    I was going to point out that he had put this in a wrong section, but that was when I was thinking he was talking about a complaining Penn State fan.
