Gtx 650 fan problem

None of the 600 series had eco/fanless settings that I ever heard of, so there's only 2 options I can think of.
1st is the fan bearings are gone dry, possibly could be rescued with some oil. Might need a fan replacement. Relatively cheap.
2nd is a possible issue with fan curves. I've accidentally sent my fan curve below the fans starting threshold, right in the middle of the curve, making the fan shutoff as it reached a certain temp, but starting again a few degrees higher.
