Winding noise while accelerating, ´08 S602.4 T5

This is an '08 S60 T5 with 11,700 km on the odometer, I have a winding noise coming from the hood when accelerating at medium speeds and the RPM at about 2,000; IF I go to a higher speed or RPM the noise seems to go away, also if I let go of the gas pedal the noise inmediately goes away.
Also, the noise seems to be more noticeable when going uphill.
If I´m parked and rev up the engine the noise is not present so it´s only happening while moving.
Fluid levels are ok, car runs just fine, I´m wondering if this is the beginning of a major problem.
Any ideas will be appreciated, Obviously I´m taking it to the dealer since it is under warranty but I would like to have a couple ideas, before hand.

If all fluids are good, then it is just the normal spool of the turbo....
A turbo will spools harder and louder under a load....
This is a pretty good video to understand turbo's functions: http://www.youtube.com/watch?v=Xp-EV...d.php?t=160381
