Whirring whine Sound

[mswaz]

Is anyone experiencing this or have experienced this. It is a whine or loud whirring sound coming from the car. Mine has just over 10K miles and I don't recall this sound earlier on when it was new, but seems to be getting more prevelent. Not sure how to describe it or where its coming from other than its mechanical and from the engine area or under the drivers seating area. Sounds as if its a vacuum pump, power steering pump, turbo whine kind of sound.

I havent noticed any decrease in perfromance and the sound is fairly constant not dependent on temperature.

Any ideas?
