Brand new bulbs make noise reguardless of quality usually. I don't know what you're using, but every bulb I've ever had buzzed a little or made a hissing noise. Some more than others, but I've never once heard a ballast digital or magnetic that did not make some sort of noise at least when you first turn it on. Maybe you just can't hear it over your fan, but I'd be willing to bet its making a noise.
No, the only time I have ever heard a bulb make noise is
A. Cheap bulbs
B. Older bulbs, make a high pitched noise as they warm up. I never have new bulbs make noise.
C. Bulbs that are screwed in improperly or too tightly.
My fan is also a overhead 42" fan, it doesn't make noise....it's a roof fan. MY BALLAST does not make noise, not at start up...not ever. My whole grow is completely silent, I sleep in the room with it.
My ballast sits out in the open and it certainly does not make any noise, the only ballasts I've ever heard make noise are.
A. Magnetic Ballasts.....fucking loud, I hate them.
B. Cheaper Ebay ballasts that claim to be electronic.
Never heard a peep out of my galaxy's . I'm not really here to debate it. My ballasts don't make noise and if they did....I'd replace their sorry asses.
