You may have nailed it here. There shouldn't be any sound at all. It shouldn't spin freely either. This is a viscus clutch so there should be some resistence all the time. Replace the fan clutch. Once you have done that, your temp gauge should read no more than in the middle most of the time. If not, look for additional cooling issues, such as the sticky manifold heat control valve.
An occassional trip to the upper third of the gauge would be normal for climbing a mountain in hot weather, but even then, I would be checking things for a potential problem. These cars had excellent cooling capacity in stock form, and when everything is working the way it should.

I have noticed that the fan makes a noise when I shut the car off, as it freewheels a few revolution - like it needs lubrication or something. It has never overheated to the point that it boils over - but, 115 is pretty hot anyway.
How do I know if the fan clutch is bad?
