Has anyone here seen these yet? Bearing-style, 10 blades and runs at 3000 RPM according to FlatRacer. The stock unit is 7 blades and runs at 4500 RPM (according to an old post I read). I don't have the ability to determine air flow differences but I wonder if the FlatRacer unit would move enough air running at 2/3 the speed of the OEM fan even with more blades?
