I was just up in that area on the driver side to pull the rope light slack out. Here are some pics and links if the pics don't show properly.
As soon as I pulled the soffit off and saw the fan some answers were obvious. I don't know what controls them. Since Tom said he unhooked them because we don't have the heavy heat generating equipment up there I may do the same thing. The noise doesn't bother me so much now that I know what it is and I'm not in a hurry to go back in there. I have a few more pressing honey-do's to get done first.
