I am amazed how simple the remedy is. Just one drop of oil, as suggested, and the overbearing drone has been transformed into a very acceptable hum. I have no idea what the decibel rating is but I would suspect it's no more than half of what is was.
Lessened noise, lessened vibration, gladened cpu. How long the quick-fix lasts depends partly upon the type of oil used (and I don't mean among engine and transmission or common hardware store oils). If you've ever heard it screech or squeal rather than just make rattling sorts of noise, you've in effect arrived too late with oil. The fair silence (sans vibration) is wonderful, for the cpu and everything else in the box. However, a cpu fan that old is yet another day closer to the inevitable, and nanodroplets of oil flung hither and thither aren't a good idea, if only for their holding dust wherever they landed. For the modest cost of replacement, while fans for that cpu are still available brand new, you might consider buying at least one brand new one to keep handy, but preferably one to mount and one spare.
