Well this is a sympton of a failed fan. When the car is in motion the air rushing through the radiator cools the engine, but at a stop with no fan to cool the radiator it will start to overheat. If the fan is working correctly we can look to the next possibility.
thank you ! will check the fan.

It could also be low coolant, bad water pump a clogged coolant hose or even air in the system.
