I would think you would center what you are taking a picture of. Therefore I am going to guess that the black square in the center of the greenery is the fan.
Hey is that Carmen Miranda?

LOL could'nt resist.

I'll put my money on it being the black spot in the center of the picture, the one in front of the make up air system.
