Static pressure is measured in mm of H2O."nine blades that together push up to 4.812 mm of water" - the wha now?
*chuckle*It also makes for a realistic sounding Airport Runway.
Bah, built-in dust filters on the fans? In most cases that would be a serious pain to remove the filter and clean it, as they'd be pinned against the case and/or boxed in by nearby sheetmetal. Best solution is filters built into the case itself. My Solo II has easy-to-remove filters on the intake.I don't really get those kinds of fans, even if the fans go in reverse, dust still clings to the case. Maybe not as much dust, but it's still there.
Now if those fans had built in dust filters right on them, that would be cool.
