Loud fan noise under hood
is it just me or does the fan under the hood sound really loud after driving for a while, and have A/C on? I have a My15 S550. When i park you can hear it wind down to a quiet state in about 20 seconds after shutting car off. Not sure yet if it’s only when A/C is on and car is hot or is it just when car is hot.

When on full blast, the fan is very loud. If it's hot, your're sitting in traffic with the a/c on and the fan demand it high, you can really hear it outside the car. Normal for the car but it is quite noticeable sadly.

That's basically the same for every MB.
Loud on the outside. Quiet AF on the inside.

It's a common Mercedes trait, across all models, the loudest A/C from outside the car, you've ever heard lol. Sounds like a drill at a aircraft plant.
