That is the way it's designed, when it's cold here when I had any of my cars in the winter, at least when I was young & drove them to school we use to bet the other kids at school that we could hold onto the fan while the engine was running & always came away with the money & a very strange look on the other guys face. But yes the fan as the car gets hopt will lock up & then cool the engine down when it comes up to temp. Don't try to hold the fan after it's up to running temp. you'll end up with hands that are all cut up & a free trip to the hospital.
