Hey Guys,

My neighbor can stand my 4" Hydrofarm In-Take fan that's connected to my light's reflector but not the squirrel fan at the bottom of my closet. It's louder, and it vibrates at a very annoying harmonic hum.
I even have both of them inside cardboard boxes which is then packed with Perlite.
I've got to replace the squirrel fan. Should I just get another 4" In-take fan and us that at the bottom of the closet to suck in air?
Or is there a quieter/non-vibrating fan out there?

Thanks for the help.
