I posted earlier about noise coming from the driver side vent, link is below but I seem to have found a little bit more info that may make it more clear

The noise seems to be coming from the general area where the left driver side air vent is but its not only coming when the car is moving. It seems to be actually tied to the engine rpm rev and only comes when the car is cold and goes away when it warms up (about 5mins or so). So when the rpm moves above 1k you can start hearing this noise. It increases as the rpm goes up to 2k or so and is loudest around 2k. The noise is there even if am stopped and in neutral and rev up the engine. The key is car is cold.
The nature of sound is some sort of revolving thing or gearing rubbing or touching something very lightly as it revolves. The sound is not loud you have to pay attention to hear it.
Could it be the tachometer??

Maybe someone else has the same noise but don't know. When you start the car try to listen for it and try to pay attention to the driver side vent area.

If anyone experience similar noise please post.
Thanks!
