   Ball bearing fans may make slightly more audible noise but they usually
last well. Sleeve bearing fans use a sintered (compressed powder) bearing
that is "lubricated for life" by oil or grease soaked into the porous
lattice. The lubrication dries out, but the bearing can be re-lubricated by
peeling back the label and possibly removing a rubber plug.
