I am looking into some fill ideas for you and will post when i have one written up. Gore-tex is a two sided material so if u try u must have the right side facing the fan....

Gore-tex is an idea that has been thrown back and forth but never tried. Thing is that I don't think it was meant to pass large volumes of air. I would try if I could get some cheap, but i bet it would be airflow killer. Not only that, things that kill airflow also often make alot of noise in the process.
