Silverstone demonstrates new Air Penetrator fan series

[meanmoe]

They're called "stators" - critical in turbine design. In turbine design, some energy is lost on the stators but it's made up for in over all efficiency by optimizing the incident angle for the next turbine row. i.e. overall energy lost to the stator rows is less than what is lost spinning the air, or something like that.

This would be better for stacked fans, but not optimal unless designed for it. It would probably be more efficient than counter-rotating fans depending on individual fan deisgn. The major advantage that I see is that, with these, you're not just increasing pressure within the case, you actually get well directed airflow. I would expect static pressure, measured normal to the fan, to increase vs not having the stators/vains/fins, total pressure would probably decrease a little.


Edit:
MpG, 0.067 in-H2O spec'd max static, I think this is inline with YLs by noise - if the spec is true. Maybe slightly better. I'd like to see the P/Q curve.
