Those who live in cold winter climates and drive their care all year understand the fan is required to defrost / defog the windshield while engine rpms are not high enough to push air and is an obvious safety requirement Porsche had to address.
But if you don't need it knock yourself out.
This also has NOTHING to do with SSIs or back dated exhaust, As you can see the SSIs route the cabin heat ducting exactly the same way.

I have backdated heat because the electricals to the blower became confused and I didn't want to dig into the wiring loom. It wasn't too hard to modify the right side fan cover, instead of buying expensive alternates.

If you are idling in traffic, you won't get a lot of heat. But whilst driving at speed you get plenty.
