    If you want to move more air you should fit a tube -maybe 6-8" long AROUND the fan cage extending towards the middle inside the box. Looks like Quaker oats or those Nesquick 72 serving tubes would work perfectly.

    i'de probably have the fans facing the other way and on the outlet side of the exhaust. the ducting has to be large, or else your just wasting energy.
    Its such a triumph of fear and ignorance over fact and logic, that the drug that kills nobody...... Is the illegal one!!

    the shorter the run the better too.for better airflow and energy efficiency.

    I got 2 pc fans, and some dryer ducting. I put a fan in each end of the ducting, and a carbon filter at the end with both fans pushing air to it. Works great, and temps are 20 degrees cooler than without it.( I'm using a rubbermaid tote with 3 CFLs)
