almost definatly your clutch fan. if its staying cool while your driving the speed is moving air through the radiator and the water pump is still circulating. but when you are at a stop it depends on the clutch fan to pull air through.

#1 cause of temp creep at IDLE is the fan clutch. Cheap and easy to replace.
That being said, a water pump is inexpensive as well and should be replaced if long in the tooth.

What is the temp it's running at? What size thermostat did you replace it with? Just trying to figure out what you are saying is hot. Yesterday the outside temp was above 85 and mine was sitting at 200 at stop signs and while driving it lowered to about 190 and that with my 190 thermostat and new water pump changed just before winter kicked in.
