  1. could be some cable that fit the fan, could be dust, could be the lubricating film on the PSU's cooling fan bearing has evaporated, could be a faulty psu, it could be a lot of things, it's hard to tell

    what brand is your psu? if the brand is bad it could be a bad psu
    also seeing your pc is only 3months old you are still under warranty, if you are worried you can RMA the psu and get a better

    it was a custom build n came with no warranty.. and its a offbrand psu "Logysis" . The dude pretty much ripped me off on ebay.. was a brand new comp but the parts he used are total shit.. biostar mobo.. its just not a stable system.. but idk what it could be.. like you said it could be a multiple of problems w the psu.. how can I test to narrow the problem? it hasnt made the noise since I tapped the side of the PSU box....

    i would just leave it for now, if it happens again buy a new psu from corsair, seasonic, antec, don't start taking it apart, it's dangerous and not something you should attempt without knowing what you are doing
