Bearings in the fan clutch went. As far as driving it to a garage, the only thing that u really risk if it does break, or seize is it taking out your radiator. If your garage is close by, u should make it there, but its not a bad idea if u have AAA to get it towed. I wouldnt drive cross state with it like that, but 5-15 miles it should stay intact. Im not recommending doing this, but in a best case senario, it should make it to the garage.
