Heres the cool part. I know its light weight carbon but it does get rid of the smell. I used it for a stelthy and inserted in a Ona gel into the filter. Bad ass forsure. 3$30 max and zero smell

there is volts and there is current, and resistance It takes one ampere to push 1volt through 1ohm of resistance. there is an voltage output and a current output rating for every power source. for example 2 12v fans with amp ratings of .3a would pull .6a of current at 12v, If your power source had a current output rating of .6a or more you could easily power the two fans. It is ok for the amp rating of the power source to be higher than the total amp draw of the two fans, you cannot however exceed the amount of amps supplied by the power source or you will fry it.

if you use the fan you have use the smaller adapter for sure the 9v would burn that small fan out.
I fear that fan you have is not going to do what you need it to do, you will need a 120 CFM 6 inch CPU fan. You can buy tehm at radio shack for 9.99$ its just a fan and wire like mine in the picture best deal anywhere.

The fans from radio shack are 12v and it is easy to find 12v adapters to run them at max, comcast little silver digital boxes come with them

110V AC to 12V DC Car Outlet Power Adapter Converter - Ebay $2
It comes with a USB adapter that I thought could come handy some time.
One screw and pull it apart.
You can see on the small circuit board which is negative wire and which one is positive. Center is positive and outsides negative (ground).
I had some spare charger around so I stripped the wires from that to attach to the negative and positive.
Close it back up with the wire coming out where the outlet part used to be. Secure with duct tape and put back in that first screw.
And to the $5 fan
Delta 80mm 4 Pin Case fan w/ plastic grill! Brand New!
Noise: 25 dBa Airflow: 28cfm
I also bought this $4
Desktop Computer 12V 3 Pin CPU Fan Speed Controller PCI
I will attach this later to adjust exactly how much sound it makes.
All for just over $10! Perfect for my veg box!

Thx for the Help. Take aThe fans from radio shack are 12v and it is easy to find 12v adapters to run them at max, comcast little silver digital boxes come with them
or And laugh about this.
After I saw your reply I wired it with the 3V adapter and it worked. The only problem is I put the fan in backwards and it sucks air IN not OUT. The other fan (6") wouldn't fit in there so I'll have to make due (once I flip it around)
Again thx and if you could look at my timer problem I would be greatly appreciative.
Exhaust and timer ?

If your grow box is 3x3x2 this small fan running at max capacity should be sufficient!
But if you have a 4x4x7 grow tent you will definitly at least need 120CFM
Also running 12v in to a small 3v fan will burn up the motor.

I have another of these little fans. It says 3V 500ma. I have several power supplies from old stuff. I have 2 of these $6 fans, so if it wears them out faster no big deal (just 1 flowering harvest would be OK). I assume the mA is a tenth of A so the 210 mA =.21mA (kinda medicated). 
I get that over 3V is over powering it, but would the 4.5V.4A adapter fail cause the fan is 500mA? What about the 5.0V 1000mA? Can I power both with it. both are 6V total so its 2.5V out of the 3V to each right? that makes more sense to me but I want them to run like raped apes
So faster is better, but 1 power supply is less clutter.So what do you guys think?
9V 210mA
4.5V .4A
7.2V 500mA
12VAC 833mA
9V 800mA
5.0V 1000mA

LMAO that's why I ask these ?s I know enough about wiring to confuse myself. I've shocked myself mildly enough years ago to check. You mean smoke from my wiring or smoke from mydoes anyone else smell smoke?

I am a first time grower on a fixed income so expenses are budgeted as tightly as possible.
One thing I had plenty of were flourescent fixtures so I decided to literally box in the girls.
They are surrounded by lights except for the one half section left open in the front for my fan to send a breeze through.
I started with a 2:1 ratio of cool whites to glo-lux tubes and now the girls are under a 2:1 ratio of soft whites to gro-lux.
It doesn't get any more bare bones basic than this and so far I have been satisfied with the progress. Two are profusely flowering while one has struggled since the start.
I know I made novice mistakes since day one but I have learned alot and will apply my new-found knowledge toward the next grow.
Peace

both if you supply more voltage to the fan then specified it will burn the fan motor.

be sure that total number mA from fans does not exceed mA output from the adapter....
