Fan and intake help!

Hey guys, im a new grower and I've just made my first ever grow box today 2x2x4. Im having trouble figuring out what kind of fan I need to use. I hear a lot about pc fans but it seems like those would get bogged down by a carbon filter right? Im going for stealth, I don't want my neighbors hearing or smelling anything they live about 25-30 feet away. Additional info im going to be growing Auto Berry Bomb so any info or tips on growing that strain would be nice. Thanks

You could go with something like this for exhaust: http://www.hydro-lite.com/frmProdDtl.aspx?Id=@E0ZPM/HxKDmvJKwF2y0jg==&CategoryId=26bVQSgOhHpor4JG8sX@5Q==&Page=rnW4@egLR3hB72E1n7SdIA==&Img=HZ8rRACfjjKaz1b233SzgtRZz145BTO/sfI35L8NtGk=&FeatureItem=&DiscountItem=&ProdSearch=

4" or 6"

Search the forums for DIY carbon filters, there are a bunch for different setups

We also need to know the lighting choice you've made.

As HID lights need alot more fan power than CFL's for example.

Im thinking about HID maybe 250w I've been reading that they are the best choice as far as yeild (note that I only want to grow maybe 1 plant at first) would cfls be better for that? Again this is all new to me so there will be some trial and error. I just cant have ANY smell im kind of paranoid right now lol

hids produce WAY more heat the cfls....hps is where its at from what iv seen but they put off a shit load of heat...im still really new to. im growing with cfls and the temps dont get crazy. the more heat the stronger fans youll need to move air out. iv seen some really nice grows done with cfls. in my opinion i think its better to start with cfls just so you can kinda ease into it. if you start with big nice things you wont appreciate it as much.

It seems you go bigger fan, throttle her back to make it quiet - I would be looking @ a 100mm centrifugal fan with fan speed control device like: http://www.pdl.co.nz/product-details.aspx?rcat=products&catid=788&id=1942

That would be my suggestion for your given light and space. Cooltube would help so much with heat also.
