I like the idea of homemade swamp cooling. Not against the dual push/pull fan configuration either. Was thinking the same thing with the blower outside pushing and computer fan inside pulling. Adjust each as needed.
For me personally it all comes down to asking if 0.25amps is low enough for low? Giving the 4" blower 12.00v still only turned it down to a 0.19amp draw. Motor ran smooth and sounded good at all speeds.
The filter does not seem to effect noise or airflow very much. The biggest airflow change i saw was using the 4" blower in pushing mode on low speed with the filter.
Here is an attempt to share basic clear to read data. All fans are sucking air and no filter. I have specs with both that are on the pages i posted earlier.
