I'm torn between a high static pressure or high air flow fan. I know static pressure is essential for radiator cooling and air flow for just general air flow into a case, but which should I get for a dust filter? I have an AZZA Genesis 9000 and there's a dust filter on the bottom of the tower. Should I get a high air flow or static pressure fan since there's a dust filter? Or does the dust filter not really make a difference.
