Whining Noise

Whining Noise
I have a 2008 S80 T6 with approx 42,000 miles that has developed an engine whining noise. The noise does not happen when the engine is cold. Once warm, it is most noticeable at 20-25 MPH especially if coasting or decelerating. At times the noise is louder than at other times. In addition, sometimes it sounds like something is rubbing against the fan blade. It does not make the noise if i rev the engine. It is not the typical turbo noise and did not make the noise for the first approx 35,000 miles. Any one else experice this? Thanks

Otherwise its most likely the surpentine belt and pulley. Again, the noise should change by turning the AC on and off if thats the case.

My 1999 T6 is doing it when shifting gears. It seems loudest just before throwing in the second gear. It's annoying and I am scared to drive the car; the garage is 370km from my location! Anybody with an idea - I would appreciate. Am able to fix a few things on this car, but this one is boggling my mind!

I'm having a valve noise issue. My wife first impression was a fan noise. But I realized that the noise was consistence with the engine RPM.
You might want to park the car (outside and not in garage), close all windows, then press on the gas pedal slowly and at different variations to see if it's the valve noise.

Whining Noise
Thanks for the input from everyone. It appears that the whining noise is from a A/C compressor that is going bad. The noise occurs in the 20-25 MPH range and it goes away if the a/c button is turned off. If you turn on the a/c, the noise returns. The car is in the shop right now getting a new compressor (thank goodness for a warranty). In talking with the tech. he said this is actually a common issue with S-80's (the a/c compressor going bad). As it is going bad, the noise will get louder and louder.

Transmission Whining
Greetings
I have an '07 S-80 V-8 AWD with 160K miles.
I have a new whining noise that's very noticeable in the cabin area.
It's a medium pitched whine that decreases in pitch as the transmission advances, but increases in pitch as RPMs increase.
Transmission has also been jerky at times, but apparently that's a software issue (?)
Always during acceleration. Quiet otherwise.
Reason for concern?
Your input is very much appreciated!
