Yeah, the San Ace is similar to the Panaflo...different bearings and a MUCH weaker blade structure (really, they break way too easily). The design also has higher CFM/RPM efficiency (but takes a hit on radiator CFM because of this).

This leads me to my next point: the high-speed 120x120x25mm market is ripe for the taking. Why lie about it when you can just do it?
