Funny sounds when turned off
 
After I turn the car off by 2 seconds, I notice a funny "fishhhh" sound like some presurized cavity getting depresurized in half a second ... What is it?

Another noise, as soon as the AC is turned off, anyone standing outside hears the electrical fan slowing down with an audible fading whining until is stops...

Anyone else experienced those sounds or knows their causes?

I have an 03 3.0i and I get the pressure release sound also right after turning the car off. Not really sure what it is also. I've always thought it was normal. Anyone else?
