E39 540i HairDryer Sound

What would cause a hairdryer sound to come from the motor?

When I drive the car it's fine and doesn't have that sound for like 8-10 mins then in the lower RPMs at least there's a really loud hairdryer sound while accelerating. If I go over 4k RPM it goes away. Is this what misfire sounds like?

By hair dryer sound, do you mean almost like a plane about to take off?
