You can run HID a few different ways. I ran it with a 6" fan and duct work going through two 1000's and a 600. Air came in my room from outdoors, went through the lights, then back outdoors. On top of that oscillating fans in each tent, ballasts whirring with their little fans, water trickling, kind of a hum coming from the room in general, but in the next room I can't hear anything.
In my room four of these 84x's on at the same time isn't really heard. I hear them turn on, but that's about it.
My room isn't an industrial complex, either. It's my man cave, too. I watch movies, blast music in there, can talk and everything and it isn't like you are talking over noise or anything. Anyway, the hums are like a background noise for me that I don't even hear any more.
The hum from an air pump in hydro will drive you insane.
