Hey, Aaron. Thought I'd let you know how it worked out...nothing changed. Gotta keep the relations happy with the in-laws.

Just one more reason to look forward to my very own studio building in the future, when the only limitations are code and $. (EDIT: Just to make it clear, I explained to my father-in-law the possibility of the fan causing noise in my gear, he looked at me like I was stupid, I explained to him how noise can be caused in studio equipment, he said "No, we're not changing it." That's that...if it wasn't for my wife begging me to get involved in this project...no use worrying about the past though, right?

)
No biggie for now. My studio's built (sans treatments), and I've noticed no extra noise from the fan. (...for now

)
Sorry if this was a waste of your time, but I appreciate the responses.
Thanks,
Dany
If it's not broken, don't fix it. If it is broken, keep the spare parts.
