The fan is usually meant to cool the radiator. It shouldn't be anything to worry about. Since the radiator cools the antifreeze that has come from and circulates through the engine, as long as the fan is running, the coolant is remaining at a good temperature and you won't have to worry about overheating.

I wouldn't bet my engine on it, but the answer is probably no. As a Dodge mechanic, I can tell you the answer is no. It will run with out oil until it seizes or blows apart.
