PC fans for filtering air w/o temp as a concern

[Agouti]

So I have my PC grow, just gutted the thing, decided upon panda film to make it light tight, and a soil grow as this is my first time growing indoors. I plan on eventually trying my hand at hydro, but for now soil.

So here is my question: I live with my parents, but figured I could hide a PC grow in my PC room off of my bedroom. However, they still do come in this room from time to time as it the only way to access the attic.

Inb4 living with your parents:
They pay for my college, if I move out, they say they'll stop. I can't turn down an offer like that, so moving on.

Because I'm using LEDs and this is in an air-conditioned house, and to be honest, my PC room only has 2 other functional PCs
(I gutted two old ones from 2001 and 2002 to take parts of their motherboard and the cover for it, which I will attach to my pc grow box, along with the power supply, which I'm hooking up to a 6 outlet power strip to simply plug in my led and my fans from inside the pc case).

So I have pc fans galore, but none of them are up to the job.
I've considered a silverstone pc fan as boasts 110 cfm for realsies, but am also looking at other 200+ "claimed" cfm pc fans.

So here's down to the nitty gritty. If I make an elbow from the filter to the fan, (to make the filter stand vertically inside of my grow space, to not get in the way of my lights), and I make one of those DIY chicken wire multilayer carbon scrubbers, will a PC fan be able to push enough air to properly clean the air from 1-2 plants? Also, what size filter to ensure I don't overburden the thing. I've heard the larger the filter, the less the fan actually has to work, and to aim for roughly 1 inch or so of thickness of activated carbon.

So in summary:

Temperature is NOT an issue, due to LEDs and air-conditioned house, but the odor is!

Can I attach an elbow from a vertical filter to a horizontal fan and still have it function?

Can a top of the line (110, or 200+ cfm) PC fan reliably push the air to make this work, if not is there something of roughly the same size that will?

What size DIY filter can I make to ensure this works properly?

Note: I also plan on putting in an ONA, and 2 room air purifiers next to this to "clean the dust because my gaming rig is just so important".

Put the elbow after the fan,imo. Separating fan and filter allows for potential odor leaks (any thing between filter and fan leaks, it a gonna smell).

I don't like to be a naysayer, but PC fans do very little if there is ANY static pressure. Your best bet is plenty of ONA with fan blowing over it. Considering risk [college costs being what they are and being at stake] I think you're better off buying your smoke and growing when you get your own place. Good luck. -granger

The silverstone offers much higher cfm (110) of what the scythe and nocturna fans offer, at 2400 rpm compared to their 1100-1300 rpm.

However, this little gem pumps out 4300 rpm, and double cfm at that. ~200. It also uses 2 amps, not milliamps, but amps.

However, I understand that cfm is not static pressure. From what I've read, static pressure is a property more of the system, than something which I can just calculate from a fan, though being new to the idea, I'm curious to know if there is a way I could calculate and compare static pressure.

To minimize the need for static pressure, I'm constructing a can from the DIY threads here using (rinsed by me) activated charcoal, chickenwire, and ducting. I figure such a can on the 200 cfm computer fan might just be enough to clear a 3-4 cubic foot box.

Of course, I'd test this thing thoroughly before ever actually growing anything in it. Here is a basic design that I have. This would be attached to the back of the tower, and expel the air, giving the impression it's a normal pc fan.

However, I'm not deadset on pc fans (despite this 200 cfm seeming to be quite powerful). I'm sure I could rig a different fan to the back of this, and still have it look like a genuine computer, if I can keep it contained in the case.

Is there a way to edit earlier messages?
I might just get a Phat brand filter for $60. It makes the claim that you need 1/2 of the cfm to make it function properly. If this it true, then it would seem any of the following pc fans I posted would function. However, if I put say, a 200cfm fan attached to a 150cfm filter, could this be TOO powerful? Perhaps it would suck the air so fast, it wouldn't have a chance to adsorb to the charcoal?

I'm not sure if you've ever seen a filter before? I just can't imagine my old 4" filter fitting inside of a PC. It's like 9" diameter and 12" long.

I must admit that I have never seen a filter. However, the dimensions on this are 8" x 8" and attaches to a 4" fan. This being said, my pc is 8" wide inside and 2 feet tall. However, the fan and filter combo, if attached to the correct area, would not give me the full 2 feet to use as filter space, and instead close to 1 foot. All in all, this should be a very tight fit, if it does. However, there are external sides, roughly one inch further than the frame of the full tower. If need be, I can carve out the frame, to get that extra inch on either side to ensure proper airflow. I've read that phat filters, compared to fresh filters, have a proper seal on them, instead of using foam in some areas, and are thus much better, but perhaps that is a topic for another thread.
