heat from the Engine Compartment After Stopping

seriously?
You don't think porsche, in their 50 years of making rear engined vehicles, figured out that you know, things might get hot back there, and planned for that?
its not a Faberge egg.

I used to close the garage door every time I pulled in but now leave it open all day and just close it at night to help it cool down. Perfect excuse to go to the garage at night and take one last look at it

I have noticed the last few months that my car oil temp has been running at around 215-225 degrees even on the same drive home from work. It's been anywhere from 75-100 degrees outside and it still runs hotter than a year ago. The fan never comes on when I park the car even though I think it should. How should I test whether the fan is working or not and what temp does it come on for you guys.

Finally, an explanation
In the 911, the locations of all the hot parts are is the same area all dissipating heat.
In a front engine car, engine's on one end, exhaust on the other. Connecting them is several feet of exhaust pipe (think heat sink) allowing some cooling prior to getting to the mufflers.
In the 911, engine, headers and exhaust are right next to each other. Heat is concentrated there.

I noticed a drop in static heat (after a drive parked in garage) after I installed the Fister cans. I had the ceramic coat added to the Fister cans for the additional $200. I used to have the fan running after switching the car off...it ran for about 10 minutes sometimes, now I haven't had it switch on.

Here's a video you might find amusing on this topic. It was taken last year on my 991, which of course has the same component layouts. The sunlight was reflecting just right of a truck windshield parked a ways behind my car and it acted like a spotlight for just a few minutes. As you can see, a lot of the heat is coming out of the wheel wells, most likely due to passing over the cats, headers, and mufflers on the way out.
I should mention that the fan wasn't running here... this was just normal convection at work.

For those new to the 911 this is all very normal. As others have observed, all the hot stuff is back there--engine, exhaust system, etc. What I used to do when I lived in a very hot climate (Oklahoma) was I would take a standard box fan, and after popping the engine lid, place the fan in the opening, propped up between the taillights and against the deck lid. I would pull the heat out (not push it down). It will ultimately preserve things in that area most affected by all that heat, light electrical wiring, and the softer plastics. I rarely do it anymore as it's just not hot where I live now. But for really hot areas, it does help.
