I believe it's not "gunking up", it's the bearings failing. As the
bearings wear, the fan can wobble on its axis. At certain speeds, the
fan will have a vibration mode where it wobbles on its axis (like a
coin spun on its edge just coming to rest). I think that's what your
noise is.

Replace the fan.
