Still, this fan does use a good amount of power to achieve what it must: spin through a good CFM flow, while producing much less noise.

Pretty well all of our fans connect at the center to a motor, right? This is just a tad different. The entire construction of fan and wheel are connected to a bearing at the center, but this is its centralized connection; nothing else.
