Usual suspect or rather culprit for such overheating is AC fan. AC fan must be bad and that's why while on idle when no wind comes from front and that's why car overheat. Check the AC electric fan in front of radiator should work when you switch on AC, if its not working then get the fan changed as its not repairable item.
