What you might be hearing is the water pump recirculating coolant through the system after you shut it off.
Mine stays on after spirited driving and you can clearly hear it.

Nope. Completely cold engine. I even opened the circular access door on the top of the headlight and the fan is definitely in there and running. In the video you can hear it stop running when the headlight is turned on and start up again once the headlight is turned off. Again, this is a cold car and cold headlights.
