My case fan all of a sudden got really loud!

  1. It just started rattling and grinding and sounding terrible. It's the case fan on the back, not the side, not the power supply or the psu, I know this because I reached in and put my finger in the fan on the back, stopping it, and it was what was causing the noise.
    It was so loud that I actually inhibited the fan so it's not working now. My case is open so I figured it wouldn't get too hot in there, but what can I do to fix the fan?
    Blowing it out with an air can didn't do any good.

    The bearings might be failing. It happens. You just replace the fan with a new one. It's easy and new case fans don't cost too much.
