I posted earlier about overhaeting. When I checked the fan it seemed like motor died. I could hear a buzz like it was trying to work but not turning. I can turn it by hand, but it is very sloppy on the shaft. The blade wobbles and sounds like it could be hitting radiator or the frame of fan. In my experience the fan shouldn't wobble that bad. Do you guys agree?

 

Seems like the fanbearing might be an issue or something is surely out of whack.Also, ifbrushes on the shaft of the fan or electric motorare worn it mightcause a buzz sound and no rotation. Can't be too sure, just a thought
