Ok...I have an iMac G5 rev B. I have had it since july and it is still under 1 year warrenty. For the past month I have noticed that the iMac gets very loud when I have it running for over 5 min. It used to only whine when I would have a bunch of stuff open but now, I can have no apps open and it will whine like it is encoding a video or something. I can hear the whine when i walk up the stars to my room which is at least a 25 foot distance. I just want to know If Apple will help me out here and realize that maybe my iMac is running to hot or something. Do I have a chance?
