I'm thinking they are Panaflo-manufactured fans. Someone
had suggested that they were Adda's but I'm pretty sure
that's not the case.

Either of those are good fan makers.

I belive these use hydro bearings. These are less expensive
to make than ball  bearing fans but are supposed to be
longer lived than regular sleeve-bearing fans. However, the
advantages of the hydro-bearing design only come into play
and high fans speeds. The lubricant is possibly a
ferro-fluid, such as is used in the voice coil gap in some
drivers in loudspeaker systems.

I wouldn't assume that they are not good fans -- but I am
again suspicious that the ratings are optimistic.

Oh heck, I have a hard enough time figuring out where to
put my loudspeakers with speakers in them. But a smaller
version of the design you are talking about is sometimes
done with peltier devices in stead of radiatiors.

Good luck,
