Yet another update.  I found the fan manufacturer's site and they have
no mention of "bearingless" anywhere.

http://www.ystech.com.tw/Tmd/tmd-0.htm

The mention of "bearingless" comes in when you start hitting the sites
that are actually selling the Areoflow or it's fan technology, similar
to this one:

http://www.mlhsystems.com/momex/NavCode/Hardware.info/ID/2159

Or this review site:

http://www.burnoutpc.com/index.php?page=reviews&review_id=150

Which lists the bearing type as Magnetic Tip Driving.  This is simply
incorrect.  Other sites with conventional fans list bearing types as
either sleeve or ball bearing.  That is how the Areoflow should be
listed; as ball bearing.

More pointedly; the Magnetic Tip Driving technology is nowhere near the
center ball bearing; it's outside the fan perimeter entirely.

Bottom line, it's not the manufacturer's fault.  The bearingless myth
started after they began selling; by the sellers.
