The more airflow, the better... almost usually always...

As for stealthness... well, you've got to work with that...

Those fans are extremely quiet!! Trust me i use 2 of them 6" 250 cfm fans one for outside air in and one for exhaust out. I keep my 4'x4'x4' box with a 400 hps at 78F with those 2 fans and use a pc fan for a extra kick inside the box! You should be fine with that fan unless your mom has hearing like a cat!!

Those fans are not truely 200cfm. I don't know how they get away with that, but if you buy a expensive in-line centrifigual fan, you see what I mean. Those HD fans are as quiet as it gets though.

Alright everyone i have some awesome news:I went and got the fan,took my old one off and installed the duct fan.....it works like a champ. Also i have sealed off my box better now there is only a tiny amount of light which i am going to seal later on today.
