Spécialement conçu pour les environnements industriels exigeants imposant un haut niveau de performance de refroidissement et de sécurité et devant répondre à des contraintes de protection spécifiques, le NF-A14 industrialPPC (Protected Performance Cooling) offre plus de puissance et de robustesse que le modèle Retail original qui a participé à la renommée de la marque. Grâce aux performances aérodynamiques exceptionnelles de son design et à l’utilisation d’un tout nouveau moteur avec alimentation triphasée, le NF-A14 industrialPPC délivre un flux d’air ainsi qu’un niveau de pression supérieurs tout en maintenant un niveau sonore ainsi qu’une consommation modérés comparés aux modèles haut rendement équivalents du marché. Son châssis en polyamide renforcé fibre de verre ainsi que le niveau certifié de protection contre l’eau et la poussière dont il bénéficie, permettent au NF-A14 industrialPPC de s’intégrer parfaitement aux environnements exigeants. Le roulement bénéficiant de la technologie SSO2 Bearing bénéficie d’un MTTF de plus de 150.000 heures. Fort d’une fiabilité reconnue et assorti d’une garantie constructeur de 6 ans, le NF-A14 industrialPPC constitue le choix idéal pour les applications les plus extrêmes imposant un flux d’air accru ainsi qu’une fiabilité sans concession.
| Les modèles industrialPPC sont des ventilateurs conçus pour les applications exigeant des vitesses de rotation très élevées. Ils sont par essence moins silencieux que d’autres modèles Noctua et ne constituent donc pas le choix idéal des configurations silencieuses de type PC. A moins de nécessiter les hauts niveaux de vitesse et de performance des versions industrialPPC, nous recommandons plutôt l’utilisation des modèles issus des autres séries (chromax si vous préférez les ventilateurs noirs). |

NF-A14 : un design éprouvé et plébiscité
Bénéficiant de plus de 100 récompenses et recommandations de la part de la Presse internationale, le NF-A14 s'est imposé comme LA solution haut de gamme pour les besoins en ventilation 140mm. Son efficacité reconnue a su convaincre des dizaines de milliers de clients du monde entier.
|
Version industrialPPC - 2000 tr./min.
Grâce à une vitesse de rotation élevée (2000 tr./min.), le NF-A14 industrialPPC-2000 apporte un gain significatif de performance par rapport aux 1500 tr./min. du modèle retail. Bénéficiant des optimisations de la gamme industrialPPC (châssis en polyamide renforcée, système avancée de protection), ce modèle est le choix idéal pour les environnements industriels exigeants.
|
Moteur tri-phasé
Alors que la plupart des ventilateurs axiaux utilisent des moteurs mono-phasés avec 4 bornes, les ventilateurs industrialPPC de Noctua sont équipés d'un moteur tri-phasé avec 6 bornes ce qui assure une transition plus souple entre les bornes et garantit donc un fonctionnement global plus en douceur, une réduction significative des vibrations et ainsi qu'un rendement énergétique sans précédent.
|
Un rendement énergétique de haut vol
Alors que le traditionnel NF-A14, avec ses 1500 tr./min., est le ventilateur 140mm offrant un des meilleurs rendements énergétiques du marché sur sa catégorie, le moteur tri-phasé qui équipe la version industrialPPC apporte un réduction de consommation de 10% à vitesse comparée (2000 tr./min.).
|
Construction en polyamide renforcée fibre de verre
La turbine ainsi que le cadre des ventilateurs industrialPPC Noctua sont entièrement composés de polyamide renforcée fibre de verre. Ce procédé procure une robustesse et une résistance encore meilleures comparées aux ventilateurs Noctua standards en PBT renforcé fibre de verre.
|
Conforme à la norme IP52 (protection contre l'eau et la poussière)
Grâce au revêtement spécial recouvrant le moteur et le circuit imprimé, le NF-A14 industrialPPC répond aux exigences de la norme de protection IP52. Ce niveau de protection garantit non seulement que ce modèle possède une excellente résistance aux dépôts de poussière mais résiste aussi aux gouttes d'eau éventuelles (l'équivalent de 3mm de pluie par minutes).
|
Canalisateurs de flux (Flow Acceleration Channels)
La turbine des NF-A14 est munie de canalisateurs de flux sur la face succion du ventilateur. L'accélération du flux générée aux extrémités des pales permet de créer une succion plus massive, moins dispersée, et accroit ainsi l'efficacité tout en réduisant les perturbations sonores liées aux vortex.
|
Cadre AAO
Les cadres AAO (Advanced Acoustic Optimisation) de Noctua sont équipés de silentblocs anti-vibrations et bénéficie d'optimisations exclusives permettant de repousser encore plus loin les limites de la performance et du silence : Stepped Inlet Design and Inner Surface Microstructures.
|
Conception en escalier de l'admission
La conception en escalier de l'admission de Noctua ajoute une turbulence au flux entrant permettant ainsi un passage progressif d'un flux laminaire à un flux turbulent. Ce phénomène réduit les émissions sonores initiales, améliore la cohésion du flux et augmente la capacité de succion en particulier dans les environnements où l'espace fait défaut.
|
Conduit de contournement à microstructures
Les extrémités des pales évoluant à proximité de la surface intérieure du conduit (caractérisée par la présence d'une microstructure), la séparation des flux qui s'opère au niveau de la succion est quasi inexistante. Cette optimisation permet de réduire les émissions sonores liées au mouvement des pales, améliore le flux d'air ainsi que le niveau de pression.
|
Silentblocs anti-vibration intégrés
Les silentblocs anti-vibration intégrés, fabriqués à base de silicone extra souple, amoindrissent la transmission des micro-vibrations tout en assurant une parfaite compatibilité avec les systèmes de fixation et les agrafes pour ventilateurs de ventirads.
|
Roulement SSO2 Bearing
Le NF-A14 industrialPPC est équipé de la seconde génération des célèbres roulements Noctua SSO Bearing, qui bénéficie des dernières avancées technologiques. Au cœur du SSO2, l'aimant est encore plus proche de l'axe, offrant ainsi une meilleure stabilité, précision et longévité.
|
Coussinets en métal
En vue d'assurer une qualité optimale de fabrication, une bonne longévité et stabilité, le NF-A14 industrialPPC est doté d'un roulement CNC usiné en cuivre massif.
|
Circuit exclusif PWM IC avec SCD
Compatible avec les systèmes de contrôle de vitesse automatisé PWM, le NF-A14 industrialPPC est pourvu du circuit exclusif NE-FD2 PWM IC pour moteurs tri-phasés. Le NE-FD2 intègre la technologie propriétaire Noctua SCD (Smooth Commutation Drive) qui élimine les nuisances sonores liées aux commutations du PWM assurant ainsi une ventilation plus silencieuse à vitesse réduite.
|
Garantie constructeur de 6 ans
La réputation des ventilateurs Noctua n'est plus à faire tant pour leur qualité que pour leur étonnante longévité. Comme pour tous les modèles Noctua, le NF-A14 industrialPPC bénéficie d'un MTTF de plus de 150 000 heures et jouit d'une garantie fabricant totale de 6 ans.

NF-A14 industrialPPC-2000 PWM test
The efficiency test, in which we test what the airflow is at a set noise level of 30 dB(A), is in our opinion the most important, because we prefer to see coolers that are silent and cool well. The best ones are the Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM and the Noiseblocker NB eLoop 140mm 1200 rpm PWM, which produce 32.7 cfm at 30 dB(A). The first one is relatively expensive, but aimed at industrial application and moreover waterproof.
|

|
Verdict du test: "The most efficient and thus "best" 140mm fans are the Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM and the Noiseblocker NB-eLoop 140mm 1200rpm PWM. Both deserve an Ultimate award." (Farzin Parham, Hardware.Info)

NF-A14 industrialPPC-2000 PWM test
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.

NF-A14 industrialPPC-2000 PWM test
Overall, these new Noctua IndustrialPPC fans are quite capable and surprisingly will not drive you crazy with the noise despite the higher RPM. The NF-A14 in particular is remarkably quiet for a fan spinning at 2000RPM. The Higher RPMs also provide users with much more range in high performance systems compared to the standard Noctua fans which are more approriate at lower RPM ranges. As usual, the only downside is that these Noctua IndustrialPPC fans cost more than the competition and despite lacking extras out of the box, a long 6-year warranty from Noctua more than makes up for it. Besides, the Ingress Protection ratings for these fans are impressive.

NF-A14 industrialPPC-2000 PWM test
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.

NF-A14 industrialPPC-2000 PWM test
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.
|
||||||
|
Verdict du test: "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-A14 industrialPPC-2000 PWM test
La gamme Industrial PPC s’inspire de deux ventilateurs, à savoir le NF-F12 et le NF-A14. Donc sans conteste le haut de gamme de chez Noctua.
Conçues pour un environnement industriel, ils sont dotés d’un châssis en polyamide renforcé fibre de verre.
Ils embarquent un moteur avec alimentation triphasée, ce qui assure un fonctionnement plus souple, génère moins de vibration et accroît le rendement énergétique.
De part sa protection à la poussière et à l’eau, cette gamme répond aux normes de protection IP 52.
Noctua propose dans cette série, des ventilateurs répondant aux normes IP67. Mais aussi des ventilateurs avec prise 3-pins ou prise 4-pins PWM.
Ils tournent à 2000 tr/min soit 500 tr/min de plus que les versions classiques. La marque propose même une vitesse de rotation à 3000 tr/min!
Le circuit PWM est associé au circuit intégré NE-FD2 PWM IC.
Le câble est revêtu d’une gaine tressée très serrée ne laissant pas apparaître la couleur des fils, il mesure 400 mm.
Tout comme la gamme Redux, point de bundle excessif… rien que le nécessaire : 4 vis.
Du gris on passe au noir mat avec des silentblocs d’une couleur marron plus prononcée que la gamme classique.
Ils bénéficient tous d’une garantie de 6 ans.

Verdict du test: "Du coté de la série Industrial PPC, on tape un cran au-dessus avec déjà des ventilateurs qui sont dans le haut de gamme de Noctua! avec du coup une orientation refroidissement radiateur (aircooling ou watercooling)
Tout est renforcé!!! la structure avec l’utilisation de Polyamide renforcé fibre de verre (versus PBT), le moteur avec un tri-phasé (versus mono-phasé) et une norme qui répond aux exigences IP 52 voire IP 67." (Bertrand Curras, modding.fr)

NF-A14 industrialPPC-2000 PWM test
Noctua has extended their fan line into radiator territory - these are powerful fans with the right form factor for rads. The relatively low prices, the ruggedness, the standard IP52 protection, the availability of IP67 protection, the long MTBF and the low, low current draw of these fans make them perfect for industrial uses as well. Finally, the color change is just what a number of people have asked for. And Noctua did not stop with increasing their 1500 RPM fans to 2000. The 3000 RPM models are where the industrialPPC fans really shine. With a simple 50% rise in output, these fans really punch out the air, both in flow and with pressure. The NF-A14 iPPC-3000 more than doubles its static pressure as it moves from 2000 RPM to 3000.

The performance of the industrialPPC fans is also nothing short of spectacular. Comparing them to the likes of Corsair’s SP120 fans, I was thoroughly impressed. When tested at both idle and full load they knocked off a good 3-4c from my overall temps. This was more than pleasing as though the industrialPPC fans are not designed to cool a Corsair H100, they had no problem showing up the fans that were made for it.

Can industrialPPC fans be used with fan controllers and resistor cables (Low-Noise Adaptors)?
Noctua recommends not to use industrialPPC fans with common PC fan controllers, resistor cables (Low-Noise Adaptors) or other devices such as potentiometers that work by applying (variable) resistance rather than actually generating different voltages such as a laboratory power supply does. Due to the higher internal resistance of the industrialPPC fans’ three phase motor, applying additional resistance will cause the fans not to start (e.g. with Low-Noise Adaptors) or to have high starting speeds (e.g. with most common PC fan controllers). Please note that the industrialPPC fans feature starting voltages between 5.5V and 6V and can be run at these voltages on devices such as laboratory power supplies or mainboard fan controllers which actually generate lower voltages rather than applying resistance. Noctua thus recommends to use either PWM or voltage based mainboard fan control or laboratory/industrial power supplies for controlling the speed of industrialPPC fans.

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.
How much torque should be used for fan screws?
Please use 0.6Nm to tighten fan screws. Make sure not to overtighten the screws as this may damage the fan frame.
Where can I find a technical documentation and specifications of the PWM speed control system of Noctua’s fans?
While using PWM (Pulse Width Modulation) based fan speed control in PC environments is usually straightforward and does not require any background knowledge, it can be vital when it comes to controlling fans via PWM in other environments. Please refer to our specification white paper for a detailed technical documentation of the PWM speed control features of Noctua’s 4-pin PWM fans. Detailing aspects such as connector types, pin configuration or RPM speed signal output as well as signal specifications and circuit design questions, it enables engineers to implement PWM based speed control for Noctua fans in custom circuit designs and applications.
Can I use Low-Noise Adaptors with y-cables / multiple fans?
Yes, Low-Noise Adaptors (L.N.A.s) can be used with y-cables, but please make sure to use one L.N.A. per fan and to place the L.N.A.s between the y-cable and the fans as shown below. Never use one L.N.A. for two (or more fans) by placing it between the mainboard and the y-cable!
I get a CPU fan error despite the fan is running!
Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.
My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?
Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:
Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.
Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.
Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.
To resolve the issue, you can:
Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.
Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.
If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.
My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?
The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:
- Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.
- Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:
Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.
Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.
Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.
If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.
I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?
The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 600 or 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.
Unfortunately there is usually no option to set a lower minimum value in the BIOS that would suit the low minimum speed of Noctua PWM fans. The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, by using 3rd party tools like IPMItool or IPMIutil, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply). Please note that any modifications performed with 3rd party tools are done at your own risk and that Noctua can not be held responsible for any possible issues.
How can I check if my 4-pin fan header supports PWM?
Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:
Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.
Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.
Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.

How should I clean my Noctua fan?
Fans inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fans regularly using a duster, slightly moist tissue or canned air. Please be careful not to use too much force in order to prevent any damage to the fan. Please do not use a vacuum cleaner as this may apply excessive force to the fan and do not put the fan under running water as water residues inside the motor may lead to short circuits.
In order to ensure flawless operation over many years of usage, Noctua’s premium grade SSO bearings are fully sealed to prevent the entering of fine dust particles. Please note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty.

Can I use Low-Noise Adaptors for industrialPPC fans?
No, Low-Noise Adaptors are not compatible with Noctua’s industrialPPC series.
Are industrialPPC fans as quiet as other Noctua fans?
The industrialPPC models are high-speed fans for industrial heavy duty applications that require enhanced cooling performance. While their outstanding aerodynamic efficiency allows keeping noise levels moderate as against comparable high-speed fans, it is inevitable that the faster industrialPPC models are louder than the slower standard models when compared at their respective maximum speeds. For example, the standard NF-F12 PWM emits a noise level of 22.6dB(A) at its maximum speed of 1500rpm whereas the NF-F12 industrialPPC-2000 PWM emits a noise level of 29.7dB(A) at its maximum speed of 2000rpm. When both fans are adjusted to the same speed via PWM or voltage control though, the noise level is similar (except for the fact that the industrialPPC fans' high-speed motors can be slightly audible at close range when running at speeds below around 1000rpm). If you want to reduce the noise levels of industrialPPC fans, we therefore recommend reducing the speed via motherboard fan control or our NA-FC1 fan controller. If you don’t need the extended performance headroom of the high-speed industrialPPC fans, we recommend using our standard, chromax or redux line models as these provide excellent quietness of operation without speed reduction.
Which Noctua 140mm fans are optimised for airflow, which are optimised for static pressure?
Noctua only distinguishes between airflow optimised and pressure optimised fans in its 120mm range (see this page for details). For 140mm fans, there is no such distinction: Both the NF-A14 and the NF-P14 redux models are true all-rounders that provide outstanding levels of airflow and static pressure. Either of them works excellent both for case cooling and for use on radiators and heatsinks.
Can I paint my Noctua fan in order to change its color?
Since even small variations in the layer of paint can lead to an imbalance of the impeller, resulting in vibrations, higher noise levels, increased stress on the bearing and thus reduced lifespan, we do not recommend painting the fan. Please note that for the reasons stated above, painting the fan will void your warranty.
How can I find out the direction of airflow and sense of rotation?
When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise:
Can I disassemble my fan for cleaning (or other purposes, e.g. painting)?
In order to ensure flawless operation over many years of usage, all Noctua fans come with a premium grade SSO bearing, which is fully sealed to prevent the entering of fine dust particles. Please note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty.

Can I run 4-pin PWM fans on 3-pin fan headers?
PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though. When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).
What pin configuration do Noctua 12V fans use?
All Noctua fans feature the standard pin-configurations set out in the Intel and AMD specifications. These standard pin-configurations are used on most mainboards and fan controllers today:
