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:] https://www.arctic.ac/eu_en/f8.html?...speed=noscript is an alternative "rifle-bore" design at considerably less cost (even if mine, per se, is not mentioned]. https://www.hardwaresecrets.com/the-...ring-fdb-fans/ 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. |
