PIWIS, Durametric, maybe some other software programs can run the fans manually. You can also hear them running if you get out of your car after a sprinted drive after getting the temps up.

Coolant level can be checked in the hatch area next to where you fill the oil. Open the coolant cap (when the car is cold!) and you can look down the tube and check the level.

I suspect the thermostat if you have enough coolant. Not 100% on the Porsche, but in general, radiator fans wont turn on when the car is running as there is airflow going through the radiators already. They turn on when the car is stopped so it can pull air through the radiator when you are stopped.

If the thermostat isn't opening, than the radiator function isn't even being used to cool down the coolant.

Here's what a mildly modified 6-speed 2.9 (IMSA ST) can do around COTA in the wet. https://youtu.be/sTC9UXOeVWc

Mildy modified? I'd like to see the mods list - doesn't look like full Cayman Sport specs but close - nice video - gives me hope. The handling of the Cayman shines through in this video.
