The hoses heat up, the thermostat is not stuck closed then.
It could be stuck open, your engine will get up to normal operating temperature if the car is sitting still or low speeds.

Get driving down the highway and you get airflow through the radiator, the coolant gets below normal operating temperature and the computer does the hanging revs because IT IS warming up.
