You may be able to extend the life of the centurion fan you have by these steps:

Is this fan a "Muffin" type fan, ie has multi blades and rotating motor housing. What we are looking for on such a fan, is a round foil label where the shaft bearing should anchor.

You want to use a squirt oiler loaded with Tri Flow, and make a pin hole in the foil to admit the oil to the shaft bearing area. Have the foil sticker facing upward as you oil the fan sitting on a work table.

After letting excess oil go where it may, wipe off excess and patch the pin hole, and then run the fan off AC or DC whichever kind of motor you have. This will work the oil into the places where it is needed. You should get easier spinning of the rotor, and quieter running. Unless you have a burr on the fan bearing, this should fix the noise and improve the smoothness of running indefinitely.

Computer stores may stock the same rating fan as New stock.
In Houston, EPO has a wide assortment of fans; some are surplus from industrial manufacturing in the area. EPO is on Fondren (west of 610 loop). They are south on Fondren from its crossing by the short tollway that takes only toll tags, the one that runs east and west.
