Default Liquid Fans for a Phosphorescent Liquid Sky

Fluid Dynamic Bearings

Stem from HDD technology. They have metal sleeves, bearings, but how
they're machined distinguishes them. For instance, manufacturer
Matsu****a’s machined bearings require a fee to reproduce [their
design] for selling them for a type of hydrodynamics.

Other manufacturers approach the sleeve machining differently, selling
them for variously whatever mumbo-jumbo approximation will stand well
in marketing.

I wanted a decent fan. Fluid dynamics being where that's at. However,
spectacularity does carry the important weight of added fees among
better machined sleeve reproduction techniques.

General MTBF are consequently outrageous, although, thankfully, that's
reducible to a workable replacement warrantee, of say six-years, on a
fan that may cost, depending, a couple or maybe three dollars.

Except they don't. Amazon, in another instance, might want to steer
you into the wonders of a $15-25 hydrodynamic contraption.

Whereas mine, an ARCTIC F8-80 mm Standard Low Noise Case Fan - Fluid
Dynamic Bearing - Innovative Design [specifications:]

is an alternative "rifle-bore" design at considerably less cost (even
if mine, per se, is not mentioned].

Order total: $7+ a tad.
Pin No. Wire Colour Wire Colour Wire Colour Power/Signal
Pin 1 Black Black Black (with White mark) Ground
Pin 2 Red Yellow Black VDC +12V
Pin 3 Yellow Green Black RPM Signal

It's going into a sound amplifier, anyway, adapted (spliced if needed)
to reflect a better replacement for a LED link to CMOS states
reporting "system" operational temperatures and cooling effects upon a
critical output stage. (More or less: Class-D amps run considerably
cooler, efficiently, than a counterpart Class-A/B),

I didn't exactly find the names I'd expected, upon choosing Arctic,
usually a product I've purchased prior from their thermal mating
compounds. What I did find, though, is there's some seriously
marked-up monkey shine in the fan business these days. $7 for nicely
boxed and shipping coverage is fine, but I'll bet Aortic is just as
much about sensibility, were I assembling or buying them for decent
prices in 5-packs at three bucks average on a unit.
