Question Fan running after car is off

Yesterday I observed what I think is a fan running several hours after the car(2015 E550 convertible) was off. The noise came from the radiator area and the engine compartment seems hot even after being off for hours. At some point it did stop but it was very concerning. My next activity is to see the dealer(but of course this is a holiday weekend). Any thoughts

A fan running for "several hours" after the car is shut off is "completely normal"? Not in my experience. I would be concerned that this could result in a dead battery.

I guess it partly depends on how hot it is where you live and how hard the car had been driven. Even then that seems a long time, mine is sometimes running for 10 minutes, never hours. But its not that hot here.

If I have been giving a turbo'd car a hard time, I will usually make sure that the lats 5 miles or so of the journey are more sedate to allow the turbo to cool a little before shutting it down.
