Jim, Try this with the CPU fan.. Get a drinking straw and some mineral oil and use the straw to drop the oil into the bearings on the fan. I've had to do this several times with older systems. It bearly takes a drop. Usually CPU fan's squawk away quite a bit when they wear out so sooner or later the vibration from that might cause CPU damage. The little bit of oil will keep the beast running until you can get another CPU fan. T H A N K Y O U James R. McKenzie jimmckenzie@earthlink.net
