Sounds like water pump has failed. Either that or the thermostat isn't opening which would be my first check since it's quick and easy to do. Since the levels were ok I wouldn't think it was a leak since even if a quarter of the coolant had leaked it should still circulate and cool the engine in the current temperatures. Did you check if radiator was hot, if the water isn't circulating the bottom left corner of the radiator where the pipe comes out to go to the pump will be cold
