Sounds to me like you have a plugged up radiator. If you have access to a lazer temp gun check the radiator when the engine is hot. Look for areas in the radiator that are cold or cooler than most. Scan side to side and up and down. If you find cool spots it is proof that coolant is not flowing in those areas. At 70 mph your fan is just along for the ride. Good luck, John
