I will be changing my setup for a more stealthy cab, I have one last question, would a 80mm(34.5cfm, .10sp) fan be enough to ventilate a 4 cubic feet box with 3 68w cfls?
I made some math and came up with numbers that says I need 7cfm(accounting for filter and ambient temps as well as the space and lights) to exchange the air once per minute, not sure how accurate that is. The fan is 34cfm, but I think I will be using a 5v adapter, to lower the sound(though sound won't matter), and I think it still gives me more than 7cfms(actually around 13cfm I think if my math doesn't fail).
5v = 40% of 12v, 34.5cfm X .4 = 13.8cfm
Is that math right? or did I input the wrong numbers?
Also, I asked this in another forum, but I wanted to ask you guys as well, the more opinions the better:
I was sketching some filter designs and came up with this, do you guys think it will work on a cab like mine(4 cubic feet, 204w cfl), or will it not be enough? I was told it was not enough carbon, would adding more carbon depth help(how much)? Any suggestions to make it better or a suggestion to build another cheap filter? Anything?
