Default Engine Noise

When I start my car cold, I hear a sort of whistling/rattling noise that lasts about 30 seconds and then it stops. When I start the car up after it has been started it does not do it. Finally when I turn my car off a different souns occurs. After I turn the car off, it takes about 30 seconds for the fan to wind down. I have no diea what these sounds are and if they are serious. Any help would be appreciated! Thanks!
