So, a while back I put together a computer. My psu, the XFX P1-650X-XXB9 worked beautifully and quietly until around 3 days ago (about 2 months after I put it together). Recently, it has sounded like its fan was on full tilt until I turned my pc off and back on a few times. Now, it is not terribly loud but is definitely more audible than before. Should I get a rma or am I just being finicky? Thanks in advance to all of the kind people who helped me.
