Is my micro-grow too big for PASSIVE INTAKE?

So I ordered a 4" inline fan with carbon filter, & it's GIGANTIC. Somehow I thought "4 inches" meant the diameter of the whole thing would be 4 inches & it's actually close to a foot wide. It's also a foot long, & with the carbon filter attached, the whole set up is about 2 feet tall. Also LOUD. This is not a stealth machine. It's on its way back.
Now, I've ordered a pc fan 120V AC Cooling Fan (http://corepcgames.info/detail/p_B004YUKWSW/Cheap-deal-120V-AC-Cooling-Fan.-120mm-x-38mm--Power-Plug-Cord-hotsale.html). Comes with a power cord, and at 42 decibels it's supposedly no louder than a refrigerater hum.
Displaces 110 cfm, so I'm hoping I can still get by with passive intake.

As long as you have good intake vents that allow good flow, that fan should be fine for passive intake. You can also try getting a simple carbon filter from the pet store and putting that over the back of the fan so that it draws the air through the filter to exit. That plus ONA gel might take care of you.
My cab (a portable air conditioner shell) is sorta tailor-made to have passive in-take at the top front, and exhaust at the mid-lower back. Would that work? I know heat rises, but I'm thinking that with a cab this small and a 110 cfm fan, I can get the air to enter at the top & pull it out the lower exhaust... ??
Anyone have a good link to info about intake/exhaust placement?
Thanks bluejeans. I'm gonna use that carbon filter idea, plus rig up a carbon filter like in the link. Hope the fan can still push air through all of that. lol
