Noise from Dashboard like a electrical fan is blowing even with engine off

[myamin]

Hello all,

There is a weird sound from the center console (around ashtray and climate control area) of dashboard within our 2004 x5. The sound is there even when engine is off and no key in ignition.

To quote another member, "The sound is like the sound that of when a CD is put in a CD drive in a computer and it starts running in the computer, or Sometimes it sounds like there is a electrical fan noise blowing from the dashboard."

Is this normal?

thx,
