Slip Streams have low pressure (small motor=low torque). so that leaves the S-Flex's, correct? "small motor=low torque" is only true for constant power input. It's easy to put more power into a fan hub, so "small hub = low pressure" just ain't so. The SFLex fans are in fact high-pitch (just not as ...

Now the question is thus: -Are my theory sound? yes. compressors in jet engines use exactly the same principle (rotor/stator arrangement). could be expensive tho! :wink: As I intend to get high end GFX at the end of this year I need all the CLEAN air I can get. It would also have the effect of a po...

The idea seems doable, but wouldn't it be easier to just buy a thicker fan ? Well from what I read the Ultra's seem to have a very clear motor whine to them. Plus the restriction of the filter + door appears to be too great for any single silence oriented fan to overcome. The biggest issue I think ...

We all know that the intakes on the P18X's are very restrictive. Yet some like me can't do with out them as we have dusty rooms. Which means having to live with reduced airflow or faster fans. Now we also know that by stacking fans on top of each other you get batter restriction handling on the fans...
