    Never had this noise before but now its making a lot of noise. Its annoying. Usually my PC is quiet, but this thing is loud all the sudden. When I get the noise, I shut off my PC and start it up and the noise is gone for about 5-10 minutes then it comes back again! I can pick up the front of the case with 4 fingers and drop it (no damage btw) and get a break in that noise. If I do that multiple times it goes to normal sound for a few min. WTF is going on? Can I fix? I don't want to buy a new one yet. Wanna fix it first.

    Hi,

    It could be several things, but the first thing I would do is go buy a can of air and blow the dust out of that thing. You would be shocked how much dust they accumulate and they can get noisy and hot when that happens. Give that a try and see if that helps.

    You're certain it's the power supply fan?

    If an excessive amount of noise is coming from the fan, it is likely that the power supply fan is failing or bad. You should first attempt to clean the fan by using compressed air to blow out any dust, dirt, or hair.

    If this does not resolve your issue you may need to have the power supply replaced.

    Hi,

    Take a shot at the air....fans collect dust very badly, but computers don't really collect that much visible dust (although they do collect dust).

    Dust can collect anywhere in there. But when it gets into fans, then it definitely needs a good cleaning. :)

    Yes, I do it all the time. Make SURE you either limit the pressure to <20 psi or use a blow gun with a very small opening. High pressure air can damage parts.

    You can replace just the fan in a ps. It is most often a standard 80mm fan. Pull the power cord and then hit the start button a few times to discharge the capacitors in the ps. Now you can safely open it and swap fans.
