    Better to pull the air through the absorbing material than to push it through which will not work very well.

    I would pull the air through the fans. It's easier to duct as well as being more efficient. Basically, the dry air can hold more water vapor than already humid air. This will allow it to absorb the pads water more, which further cools the pad, and cools the air.

    I provided a link in the original post that will calculate the cooling effect based on your conditions.

    The higher the humidity, the higher the dew point (the lowest temperature you could achieve). If the dew point is higher, the cooling effect is diminished; it is now cooling to a higher temperature.
