Thanks guys. Yeah my impression was that the hot air was coming out of the fan bay rather than the generator bay.

Unfortunately, I listened to a couple of other side-mounted gensets while I was in Miami, and they sounded about the same as mine... so I am probably just sensitive to it. It is not super objectionable, it's just far from quiet. Somehow Marathon manages to make the whole system almost inaudible even when outside! I was thinking I would figure out what they do and copy them.
