Assuming that you didn't do this when cleaning the fans, try lubricating their bearings and check if that resolves the problem.
Usually with most DC fans if you gently peel off the fan maker's label in the centre of the fan you may find a rubber seal that is covering the bearing.
Gently remove the seal and apply ''1 drop (only)'' of a light grade machine oil (sewing machine oil perhaps) onto the bearing and then reseal it and replace the label (if possible or cover it if the label won't re-stick).

Worth a try.
