Noise with engines off?

Just got my spark - really excited!
Charged battery,
Updated the firmware and registered the product.
Now... I notice when I turn the battery on, before the engines rev up, it makes a pretty large whoosh sound, almost as if it has a loud fan inside.
Can anyone else confirm that this is normal? My phantoms do not have any noise when idling...

Pretty sure my Mavic has internal cooling fans, so no surprise if Spark does as well.

It does have a cooling fan that draws air in through one of the top side vents and blows it out of the other..
