Vortex-Control Notches

Vortex-Control Notches

Noctua's signature Vortex-Control Notches split up trailing edge vortices and thus spread the fan's noise emission over a wider range of frequencies. This measure makes the fan sound more pleasant to the human ear.
Bevelled Blade Tips

Reducing critical rotor stator interaction, Bevelled Blade Tips permit to combine extended leading edges and a higher blade surface area with quieter operation and thus form a cornerstone of the fan's outstanding efficiency.

The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the fan remarkably quiet even at very close distances.

NF-B9 redux-1600 Review

REDUX verze stále o parník překonávají provozní kvalitou drtivou většinu ventilátorové produkce. Přitom pořád nabízejí 6 let záruky, vynikající výkon při nízké hlučnosti a zkrátka se musíte obejít bez nejnovějších vychytávek a rozsáhlého příslušenství (musíte si vybrat napevno danou verzi s otáčkami a PWM). Jenže finanční úspora je také velká. Běžně jsou REDUX verze o 120-150 korun levnější, než jejich hnědé luxusnější verze, což už je pro řadu uživatelů dost znatelná úspora. V případě nákupu tří kusů 120mm hnědých modelů NF totiž zaplatíte tolik (1500 korun), že za to máte 4 kusy REDUX verze a to už se při osazování skříně u mnohých prostě počítá. Ovšem právě jen do skříní bych ty REDUX verze doporučil (na to jsou i určeny). Pokud je chcete na chladič CPU, či výměník vodního chlazení, na to jsou tu speciálně optimalizované ty hnědé modely a vyplatí se do nich jít. Pokud jde o ty IndustrialPPC model. Pro drtivou většinu domácích uživatelů nebudou zajímavé. Jsou hlučné. Ale to je vlastně jejich jediná nevýhoda a je to vyváženo ohromným průtokem vzduchu a tedy obrovským výkonem, při TOP kvalitě zpracování, zvýšené odolnosti proti vlhkosti a prachu a záruce dlouhé životnosti. Cena je ovšem hodně vysoká (stojí o 130-140 korun víc než hnědé verze). Ale pokud vám jde předně o ten výkon a chcete si být jisti, že vám to i chvíli vydrží, nemůžete s nimi udělat chybu. Jsou opravdu famózně výkonné. Strčte je na výměník vodního chlazení a poskytnou vám maximální účinek - ale nepočítejte s tím, že budou tiché.
Test verdict: "Obě nové řady jsou velmi vítaným zpestřením nabídky ventilátorů." (Jan Stach, DDWorld.cz)

NF-B9 redux-1600 Review

The redux fan series is Noctua’s answer to system builders who have been demanding options of a more affordable and alternately colored fan. Packaging has been streamlined compared to the regular retail version but the build quality is still excellent and top notch despite the lower price. Most users can live without the extra accessories as most fans available in the market come just as bare anyway. The color choice is excellent with contrasting two-tone grays that still look unmistakably Noctua while fitting in and standing out at the same time inside a system.
Test verdict: "Overall, Noctua’s redux fans easily stand-out from the rest of the market because of their high build quality and new sexy gray color scheme. Utilizing proven Noctua technology offered at a lower price point with the same long warranty as the current Noctua retail crop, the redux series is a must-have for those looking for silent cooling solutions."

NF-B9 redux-1600 Review

So if the coffee and cream color of Noctua's fans were the only thing holding you back from enjoying the highest quality in cooling components for your computer, well jump up for joy cause the new colors offered by Noctua are awesome. With the added benefit of style, no quality was sacrificed and these line of fans performed well and a few of them at max RPM could barely be heard over the ambient noise. The braided cables are nice touch also. The fans carry a 6-year warranty offered by Noctua. These fans perform exceptionally well and look good while doing so. These fans move massive amounts of air and achieve very reasonable dB levels at maximum RPM.
Test verdict: "The new colors offered by Noctua are fantastic. The Redux models are premium quality, quiet and priced competitively. The industrialPPC models are heavy duty models that will meet the demands of the most extreme conditions." (Chris McCart, FunkyKit.com)

NF-B9 redux-1600 Review

The first, the redux line, is taking its naming very literally. The redux line is reaching to the back of the top shelf, dusting off all of the oldies but goldies, and re-releasing them as a baseline product to catch the attention of the more economically inclined. However, there is one twist. A brand new, and long overdue, color scheme update. The new redux models are all coming in a light/dark contrast gray, paying homage to the original light/dark contrast brown that was their roots. Now, I know what you're thinking, "why older, out of date fans?". My answer is simple: Though the models are older, they are also what put Noctua where they are today and should not be underestimated. [...] The grand finale is the industrialPPC series. There are not likely fans at the 140mm size that can match these thermal killing speed demons. They are an overclocker's dream. Throw a couple of these at a water cooler and heat dissipation will never be better. At nearly 50 Celsius I had nothing but head room for additional overclocking.
Test verdict: "All of these fans are great, even if it is their second unveiling. I think that with the release of the industrialPPC and the redux, Noctua has every base covered. Easy to please base users who don't have much need for insane power or quiet, sound enthusiasts who need to work with little to no sound, and those who have a need for speed to keep their CPUs from frying during heavy overclocking."

NF-B9 redux-1600 Review

Noctua has knocked down the prices of their classic fans, changed their colors, and moved from a full course meal to an a la carte menu for their accessories. The price reduction should open up a new part of the market, the new colors will stop turning off purchasers who hate the old colors, and having the accessories available separately will allow people to buy what they need. These are good fans. That NF-S12B is a surprisingly good fan. It was right up with the NF-P12 in pushing through the radiator. It helps that these fans are now not only price-competitive with comparable fans, they beat most of them with their reasonable prices. And let us not forget: all of the packaging is easy on the environment. It is all completely recyclable. If you have bought a heatsink from Noctua, you know it is a tradition for them. Now we see it in their fans. Good job! The biggest pent-up demand is probably in the NF-P14s redux. The NF-P14s redux is just what many users have been asking for: a square-framed 140mm Noctua fan that can really blow through a case, do it quietly, and look great so you can show it off.
Test verdict: "A new styling theme, excellent performance and a refined accessories kit allows the Noctua redux series to pick up our prestigious gold award." (Ed Hume, Vortez.net)

NF-B9 redux-1600 Review

Ultimately, Noctua makes a great fan, but they fit best with people who have the higher budgets for them. [...] I never see the level of quality in manufacturing from other brands that Noctua puts in their product and they match that with a massive 6 year warranty. Because of this, we happily award all fans in this round up with the PureOverclock Great Hardware Award!
Test verdict: " These are great quality fans for those who prefer elegance over flashy appearance and don't mind spending a premium for them." (Josh Jackson, PureOverclock.com)

NF-B9 redux-1600 Review

Each of the fans comes with mounting screws and is extremely simple to install. I installed each Redux fan in my test system then put them through their paces running the Witcher 3 at maximum settings on a GTX 1080Ti at 4K. The fans each remained whisper quiet even under full load, which is great news for hardcore gamers. But if you’re more of a casual gamer, and mainly use your PC for work or surfing the internet, you’ll barely notice these fans are on. This makes them a perfect choice for mini-ITX builds or a rig you’ve designed to sit under your TV in the living room.
Test verdict: "If you’re building a gaming PC, first make sure you don’t overlook cooling, second make sure you consider Noctua’s excellent line up. Recommended." (Chris Sealey, Building a Gaming PC)

NF-B9 redux-1600 Review

The attention to details is present everywhere and even though Noctua had to cut corners, they didn’t go overboard and kept what you would like to see like the fully braided cables and top-notch packaging that defiantly makes you feel like you are getting a high quality product at a good price.
Test verdict: "So, this Redux series is addressed to those on a budget, Noctua focusing on exactly what you need – a really good fan. So you will still get the SS0 bearing, very good performance and 6 years warranty with over 150k hours of MTBF. " (Alex Nistor, Glob3trotters.com)

Noctua ancora una volta si è dimostrata all’altezza delle aspettative, è riuscita a commercializzare ventole dall’alto rapporto qualità/prezzo pur mantenendo costi contenuti. Eccellente come sempre la qualità costruttiva, si rivela versatile per diversi utilizzi mantenendo costi interessanti. Molto buono il packaging, sempre molto curato, sufficiente il bundle, c’è lo stretto indispensabile.

NF-B9 redux-1600 Review

Una vez montados y en funcionamiento los ventiladores en el PC, lo primero que nos percatamos es el poco ruido que genera. En general, todos los modelos de la serie Redux son muy silenciosos e incluso estando al 100% son difíciles escuchar. Los más silenciosos de toda la gama son los ventiladores pequeños, qué puede ser a causa de tener las aspas más pequeñas.
Test verdict: "En esta valoración, hemos tenido en cuenta tanto las características técnicas, rendimiento y precio para valorar este producto. Los ventiladores tienen un precio muy bajo, pero sus características técnicas y el rendimiento son espectaculares." (Carlos Carraveo, PcGaming.games)

Information Sheet (PDF)

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?

Noctua 12V fans comply with the established specifications for standard PC systems issued by Intel and AMD. Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often deviate from these specifications e.g. by using proprietary fan headers, custom pin-alignments or pin-configurations, different methods of fan speed control, etc. This can lead to compatibility issues when using Noctua fans in systems from said brands. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues (e.g. errors or shutdowns due to low fan speed) can often not be resolved. As a result, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.
