I have a noise that pops up out of nowhere. I've checked all the fans, even had the GPU disconnected and the little speaker too, and it still happens. If I put the PC to sleep or shut it off, and turn it right back on, the noise is gone for a while. Sometimes it comes back in 10 minutes, sometimes an hour, but it always comes back.
