Closet is 6 X 2 X 8. 351 CFM is at max speed which I hope not too need very much...... maybe on the hottest days of summer when the closet gets pretty warm.

I will just put it in and crank it up and see how it sucks and blows. :) It is not rocket science. Just thermo and fluid dynamics. No biggie.

I do not know the BTU load of each component. I could try finding those numbers I suppose. But it seems that there are different ideas when it comes to how much air you need to move for a given BTU load. Middle Atlantic, ATM, Cool Components, ACInfinity, all have different figures and explanations on what is the right way to do it.

I hope this is not a hoax!
