    Hi, it's me with another PSU problem, as if my endless streak of PSU issues isn't enough.

    My brand new Xigmatek NRP-MC651 PSU (only 1-2 weeks old) started making a strange clicking/crackling noise.
    I pulled it out and listened carefully... It's the fan, 100% sure. This clicking noise slowly starts to occur as the fan starts to spin and fades away as the fan slowly lowers it's RPM.

    I also tried to blow some air into the fan when the PSU is off so that I can make sure it's not the PSU, and while it's spinning it also generates the clicking noise (altough slighlty faint as I can't turn it's rpm high by just blowing on it).

    The PSU does not overheat, it's only slightly warm on full system load.
    I don't have any other capable backup PSU around so I can't RMA it.

    My system doesn't require full 650 W, just about 500-550, so the fan controller will never set the fan on higher rpm.

    The only capable PSU I have / will have is a TT TR2 550W will I sent to RMA and still waiting for it.
    Should I worry about the fan getting loose and going razor style inside the PSU? How long until it fails completely.

    Also, here's the most important part. I recorded this sound. Here it is : http://www.youtube.com/watch?v=otB-pSvFjqY

    Could be something as simple as a loose wire hitting the fanblade. Could be the fan itsel fis loose in some manner. I say contact Xigmatek and see if they offer an advanced RMA service.

    Crucial offers the service with a twist. They will send out another product but require you to place the cost on a credit card, when they recieve the bad product they credit back to the card. Worked twice for me without a hitch.
