What is the best kind of stop leak for radiator?

Assuming you are referring to a car radiator, there are of course a variety of manufactures that make a "stop leak" out there and depending on how bad the leak is ultimately I would advise taking it to a qualified mechanic (if finances permit) and have the leak fixed professionally. Alot of these things on the market to stop a radiator leak are only temporary at best. They weren't meant to be a permanent fix. Reason being, the radiator builds up alot of heat to the point that any kind of putty type stuff or even one that you put directly in the radiator that is suppose to plug up the leak from the inside will eventually give out due to the amount heat. Basic science: Heat expands things. Maybe not the answer you were looking for, but .

Why is it that when the radiator fan is on white smoke coming out from exhaust disappeared?

A small leak in a head gasket. When the engine is hot the head expands and the leak opens up. When the cooling fan comes on it removes some of the heat and the leak closes back up. This will not last, the leak will get bigger and leak all the time.
