Is not overheating while driving because air is being forced onto the engine and is keeping it cool. Once you stop the cooling effect stops. If you have a Crack in the radiator then you need to change the radiator out. Your losing coolant that's why you see steam. Once the coolant hits the hot engine it vaporizes and turns to steam.

If the electric fans aren't working it can have those symptoms and also engine fan clutch. On hot days with AC running it kinda needs them all. When the radiators get old the material they are made of gets a bit crispy, time for a new radiator.

How many miles on car? That crack will grow from the heat cycling and better to get it replaced ASAP. The possible result for letting it go is that you'll be talking with your mechanic about a blown head gasket situation. As in lots of steam coming out the exhaust along with a chocolate milk color to the coolant or oil. That's to late by then and with warmer weather coming on, this is a definite bad situation.
