Can be multiple things t, whens the last time the radiator has been washed out, also can you hear the fan come on very loud noise should be heard if not there right away you should know you have a fan problem. i Would also check the play on the water pump bearing/idlers,belt make sure its not to loose or anything is worn out.  Also have you checked your lower rad hose if you can feel its not even close to being as hot as your upper hose then right away you know your thermostat is geting stuck closed. Also how fast is your tempature gauge rising? how long is it taking to overheat.
