Welcome to Android Central. Which device are you using? Does it have a removable battery? If so, try pulling the battery and re-inserting it after a couple of minutes.

Welcome to Android Central! If it's a Samsung device (and you can't pull the battery), press and hold Power and Vol Down together for about 10-15 seconds to force a shutdown.

And get rid of that cool-down app. It's useless, and probably came with tons of adware or spyware.
