With out being there in person to see what the real problem is, it is really tough to diagnose this kind of a problem 'on line' so to speak. It sounds like you did not properly align your fan on the new radiator, so it is rubbing on something. As for the charging system, dead battery problem, start with the basics and fully charge your battery and then disconnect it as it sits over night. Reconnect if it and if still won't start your car in the morning, then you have a defective battery. If the car starts, then you have a drain. Best of luck and let me know if I can assist you further.
