Wiring details, service manuals and repair information is shared in this thread
That might help you out.
Seems the cool down feature of the car is somehow broken.
That is needed when you have driven quite enthusiastically before shutting down the engine to let it cool down the heated parts enough, not to let them bent, or even eventually break.
Also you might want to take a look at the level of your coolant (and maybe change the coolant if you are unsure when it was done the last time). That might be filled too low, OR might have big air bubbles in it, making it heat up at some unwanted spots, which triggers the cooling fan. It also can be pretty dirty, making it much less effective.
In the cooling fan repair manual it says:
With engine coolant temperature below 190°F (88°C), turn ignition switch to ON position (engine off).
Ensure fans stop.
If fan does not stop, test cooling fan relay and ECT switch/sensor. See COOLING FAN RELAYS and
ECT SWITCH or ECT SENSOR . Check for loose or broken connector or wiring between relay and
ECT switch. Repair as necessary.

Hope this helps!
