Computer fan carbon filter IDEA

I was thinking... I know computer fans have shity SP, or torque per say, so i was wondering, would putting two fans back to back help the pressure of air at all for a carbon filter? Any ideas? Feasible?


Heres my pic. ))=== cell phone cameras arnt the best hehe.
but seriously, get the idea?

Doubling up the fans will increase the pressure. I may not have a lot of experience growing weed, but I am a mechanical engineer.
