My 2000 Grand Prix is making a whining noise (sounds like a propellor). I dont hear it until I am around 30-35 mph. The noise subside when decelerating. Revving the engine in park does not produce the noise. I replaced the serpentine belt yesterday, but the noise is still there. Can you give me some ideas on where to look?

After you've got the car up to speed, put it in neutral and let it coast for a while.
If the noise is still there it's road noise from the tires, or wheel bearings.
If the noise goes away, something is wrong in the drive train.
