Hey, recently my 2 year old xfx pro 450w started making a strange clicking noise which gradually lowers and heightens in volume (sometimes it dissappears) when my computer is on. I have already filed for an RMA but it would be nice to get some info about anyways and see what kind of case i can make. Someone else has had this problem before and has made a video about it here (its nearly identical to my noise). Thanks for any and all answers.
