All air intake pipes up to throttle are well connected, vacuum reading is good, idle stable, air intake to cabin hose is disconnected, A/C off, so air system is in good shape
If this is from inside the cabin, perhaps take a look at the temperature sensor fan on the instrument panel or look into the seat back fans. I agree that generally it does not sound like a bearing though. It is hard for me to hear in that range but it seems like a harmonic that something is emitting.

I checked the temp sensor. What is the seat back fans ?
On the back side of the seat is a screen that has a fan behind it. Item #21.
I really doubt it could be the source as the sound is more of a whistle than what I would expect to hear as whispy from that component.
That fan is not an option in 2008 model, only from VIN 32753
Also, as mentioned, the noise follows precisely the engine revs so seems that it can't be from the cabin after all
Sounds very similar to alternator whine in stereo system. I know you said the stereo is off, but is it possible that the amp may still be getting power and feeding noise thru one of the channels? Just a guess...
Alternator is a real suspect for sure
thats why I disconnected the speakers to make sure its not electrical induced noise
is there any additional speaker under dashboard such as burglar alarm or so ?
however it seems to me that the alternator bearing is whining at some level so maybe mechanical induced noise with all that aluminum monococ structure ?
i plan to make some access to the front pulleys and check them all
what is the easiest way doing so ?
This may sound crazy but you should also check your transmission mount. When it's wrecked, the transmission sits in an awkward position and can make all sorts of weird noises in conjunction with the driveshaft.

Transmission and engine mount are brand new...one month old. Thanks anyway, it's not crazy at all...
I have seen that back picture of instrument cluster
seems like there is a speaker on the right side so i suspect it may be the source of the whining noise i experience
Anyone knows if that's a speaker?
How difficult is to remove it to check?
I realize the need for privacy, but don't understand why some Forum members refuse to provide a general location such as city and state. I usually don't reply to them.

That would be so more pertinent info could be provided to further assistance given to other members. Why would someone want others to suggest going to Edinburgh when they live in Seattle?
