El Galardonado Diseño S12
El NF-S12A dispone de la tercera versión de la evolución del clásico Diseño de Aspas Rectas de Noctua que ha logrado innumerables recomendaciones de periodistas especializados en hardware y entusiastas de todo el mundo para su serie S12. Mejor optimizado para una aún mejor eficiencia de flujo de aire por ruido, haciendo que el NF-S12A sea un ventilador de caja silencioso ideal.
|
Anti-Stall Knobs (Bultos Anti-Estancamiento)
Los del NF-S12A reducen el fenómeno de separación del flujo en situaciones de impedancia media y alta aumentando por tanto el margen de estacamiento del ventilador. Esto significa que el NF-S12A es aún más versátil que su reconocido predecesor y puede alcanzar mejor rendimiento en disipadores y radiadores.
|
Marco AAO
Los marcos AAO (optimización acústica avanzada) de Noctua cuentan con almohadillas antivibración integradas, así como con el diseño de entrada paso a paso y las microestructuras de superficie internas (ambos propiedad de Noctua), que perfeccionan aún más la eficiencia sonora y el rendimiento del ventilador.
|
Diseño de entrada paso a paso
El diseño de entrada paso a paso de Noctua añade turbulencia a la entrada de aire para facilitar la transición de flujo laminar a flujo turbulento, lo que reduce el ruido de entrada tonal, mejora la adjunción de flujo e incrementa la capacidad de succión, especialmente en entornos con espacio restringido.
|
Microestructuras de superficie interna
Con los extremos de las aspas del ventilador en colisión con la capa límite creada por las Inner Surface Microstructures (microestructuras de superficie interna), la separación del flujo desde el lado de succión de las aspas mengua de forma significativa, lo que resulta en un ruido de paso entre las aspas menor, mejor flujo de aire y mayor eficiencia de presión.
|
Almohadillas antivibración integradas
Las almohadillas antivibración integradas, fabricadas en silicona extrasuave, minimizan la transmisión de las vibraciones por minuto, a la vez que mantienen la compatibilidad con todos los sistemas de montaje estándar y clips para ventilador utilizados en los disipadores.
|
PWM IC de diseño propio con SCD (Unidad de Conmutación Suave)
Con soporte total para un control de velocidad PWM automático, el NF-S12A PWM usa el nuevo NE-FD1 PWM IC de diseño propio de Noctua que se integra con la tecnología Smooth Commutation Drive (SCD, Unidad de Conmutación Suave). Proporcionando impulsos de par más suaves, el SCD disminuye los ruidos de cambios del PWM y hace que el ventilador funcione de forma más silenciosa a velocidades bajas.
|
Detención a 0% PWM
Cuando el ventilador esté configurado en un ciclo de funcionamiento de 0% PWM por la placa base o un controlador de ventilador PWM se detendrá. Esto lo convierte en el idóneo para instalaciones con refrigeración semipasiva que apaga los ventiladores automáticamente y, por lo tanto, funcionan completamente en silencio cuando se encuentra en reposo si la temperatura interior lo permite.
|
Low-Noise Adaptor (Adaptador de Reducción de Ruido)
El NF-S12A PWM viene con un Low-Noise Adaptor L.N.A. (Adaptador de Reducción del Ruido) que reduce la velocidad máxima del ventilador de 1200 a 900 rpm. El L.N.A. se puede usar tanto para usar el ventilador a una velocidad fija de 900 rpm como para fijar una velocidad máxima al usar el control de PWM automático.
|
Opciones de Cableado Extensible
El corto cable principal de 20cm del ventilador minimiza el lío de cables en situaciones típicas mientras que el cable de extensión de 30cm que se suministra permite un alcance extra cuando resulta necesario. Ambos cables están totalmente forrados.
|
Rodamientos SSO2
El NF-S12A dispone de los reconocidos rodamientos optimizados SSO de segunda generación de Noctua. Con los SSO2, el imán posterior está situado más cerca del eje para proporcionar mayor estabilidad, precisión y durabilidad.
|
Cojinete de metal
Con el fin de garantizar el máximo grado de precisión posible en su fabricación, una tolerancia mínima y una excelente estabilidad a largo plazo, el NF-S12A usa un cojinete CNC fresado hecho totalmente de latón.
|
6 años de garantía de fabricante
Los ventiladores de Noctua son conocidos por su impecable calidad y su larga vida útil. Como todos los ventiladores de Noctua, el NF-S12A dispone de una MTBF de más de 150.000 horas con una completa garantía de fabricante de 6 años.

NF-S12A PWM Opinión
The Noctua 1200RPM fans (FLX and ULN) posted generally better scores than the SilverStone AP123 fans despite running at lower RPMs and being quieter. I think the results speak for themselves. [...] So we have a great deal of performance flexibility across the whole NF-S12A series, we have the extensive Noctua accessory bundle with each fan giving you even more flexibility to use your fans whichever way you want, we have the usual top notch build quality and reliability backed by Noctua’s 6 year warranty, we have mind boggling levels of research and development that have gone into these products and most importantly a price which is still competitive despite this best-in-class excellence that you just don’t expect to find on most fans. As I always seem to say with Noctua fan reviews the price is justified by the premium nature and excellent all-round capabilities of the product. If you want some excellent case fans then you cannot go wrong with the NF-S12A series. My only concerns are that relatively speaking the price is high, but like I have said I still feel this is justified, and again the aesthetics will not be to everyone’s tastes but the brown and beige colour scheme is what makes Noctua products unique. Without it they would just blend into to a market full of average fans when their fans are certainly far from average, though I do feel they could have made an effort to braid the cables all the way into the motor so the multi-coloured cabling on the rear isn’t visible.

NF-S12A PWM Opinión
Im Einsatz zeigen die neuen Noctua-Lüfter dann sofort und nahezu uneingeschränkt ihre Stärken. Schon nach wenigen Sekunden ist klar, das sich die Geräuschemissionen des schon vom Werk aus recht leisen Nanoxia Deep Silence 1, noch weiter senken lassen. Als wäre dies nicht genug, lassen sich die beiden NF-S12A, wie auch der NF-A14 in ihrer Arbeitsgeschwindigkeit leicht nach unten korrigieren, ohne dabei an Performance, in diesem Fall Kühlleistung bzw. Luftdurchsatz, zu verlieren. Ein klares Zeichen, das Noctua mit der dritten Generation seiner NF-Lüfter, doch noch einen, wenn auch nur kleinen Schritt nach vorn machen konnte und im Premium-Segment nicht nur bei der Ausstattung, sondern auch der Leistung weiterhin Maßstäbe setzen kann. Ebenfalls lobenswert ist das breite Drehzahlband, welches von den NF-Lüftern abgedeckt wird. Die Spanne reicht hier, fein gestaffelt, von einer Anlaufgeschwindigkeit knapp unterhalb von 600 U/min. (ca. 50 %), bis hin zu leistungsorientierten 1200 U/min. (100 %).

NF-S12A PWM Opinión
Noctua has devoted itself to quiet cooling. In that they have succeeded well. One measure of their insistence on quietness was their not bringing PWM products to market until they were ready to do it the Noctua way. “Fans” of Noctua’s fans long wrote about how they wanted PWM versions, yet there were no PWM fans from Noctua. But it turned out that Noctua was not ignoring PWM; their engineers were working on developing a silent PWM control. The clicking seen in other PWM fans – even quiet clicking – is completely absent in Noctua PWM fans. This started with their NF-F12’s, and has now extended to their A series. All are clickless. As well as can be measured in a non-professional setup, Noctua’s airflow specifications are accurate. You can listen to a fan and hear if it is quiet or not, and whether it makes unpleasant noises (Noctua fans are free of unpleasant noises). But airflow is another matter. Airflow takes special instruments to measure. It is comforting to know Noctua’s specifications on this are accurate; so you can use those specifications in your buying decisions.
The various Low Noise Adapters and Ultra Low Noise Adapters are different for each of the fans. Clearly, they are tailored to achieve particular results. This may or may not be unique to Noctua fans. Interestingly, Noctua says nothing about it. The Noctua accessories are of good quality, and appear likely to last in extended usage. They are all handsomely sleeved as well. The fan frames are sturdy, and the corner cushions do not extend into the screw holes. That means the fans can be securely fastened with or without the cushions.

Resultado del análisis: "Overall, the Noctua A series is a fine set of fans. Careful attention to airflow and acoustics, along with the best PWM circuits in existence, make these superb fans." (Ed Hume, Vortez.net)

NF-S12A PWM Opinión
Noctua products are far from typical, not just in terms of aesthetic with the unique love-it-or-hate-it beige and brown color scheme but in terms of build quality as well. At its core, a cooling fan is essentially just a set of impellers rotating to push or pull air but Noctua fans takes the idea one step further and hones the science of cooling to an art form. This is evident from the moment you open the box and see the organized packaging and the accessory kit, carefully chosen with so much consideration. Every cable is covered and even the labels are printed in thick glossy paper and will not easily come off over time. The Noctua S12A series fans are premium products after all and it is also very evident in the price. While most case fans have an MSRP of $10 to 15 USD, the Noctua S12A costs $27 USD per fan (The lowest price currently that I could find is $23 from Amazon.com). Considering how much R&D Noctua puts in to their fan designs however, this isn’t surprising. Also, the build quality is beyond compare so it is somewhat justified. Is it practical? It is about as practical as a Ferrari in that it is an investment for the long run instead of just for the current build. With a MTBF of 150,000 hours and 6-year warranty, the Noctua S12A will outlast multiple system builds so it essentially pays for itself after a while. In terms of performance, the Noctua S12A series are designed primarily as a case ventilation fan. Despite improvements in design compared to its predecessors, Noctua offers the NF-F12 and the NF-P12 fans as superior choices for heatsinks and radiators due to their static pressure performance which the NF-S12A lacks. In our testing, the S12A was noticeably very quiet without any high pitch whine at maximum voltage and had a very even airflow distribution compared to other fans. Even when the low-noise and ultra-low noise adapters were added, the performance did not drop significantly and still cooled the overclocked CPU decently.

Resultado del análisis: "Overall the Noctua S12A series provides flexible cooling options across three different versions. The price is noticeably higher than other fans but considering the longevity promised by the excellent build quality and the lengthy 6-year warranty, users eventually get their money’s worth. For the Noctua S12A’s technological innovations, unique design and extremely silent performance, it earns the HiTechLegion Editor’s Choice Award." (Ron Perillo, HiTechLegion.com)

Kotelotuulettimissa on selkeitä mitattavissa olevia eroja. Noctua NF-S12A oli testatuista tuulettimista keskiarvoisesti paras, mutta ei järin suurella marginaalilla. Halpa Zephyr 120 tarjoaa samoilla kierrosnopeuksilla samanlaisen määrän jäähdytystehoa Noctuan mallin kanssa, mutta pitää huomattavasti kovempaa, ja epämiellyttävämpää ääntä.

NF-S12A PWM Opinión
İncelemedeki NF-S12A PWM modelinin Türkiye fiyatı 110 TL. Amazon üzerinden alırsanız 10 TL daha ucuza geliyor ama o kadar fark için beklemeye değmez. Ancak üç ya da daha üzeri alımlarda daha mantıklı olur. PWM modelinin haricinde aynı fanın FLX ve ULN modelleri de mevcut. Tek farkı hızları olduğu için ve PWM modeli son derece sessiz olduğu için diğer iki model çok mantıklı değil. Eğer klasik Noctua renkleri size göre değilse Chromax ailesinde siyah versiyonu da var ve yaklaşık 17 TL daha pahalı. Ama kutu içeriği yok diyebiliriz incelemedeki modele göre. NF-S12A PWM modeline daha ucuz alternatif isterseniz Redux serisinden NF-S12B incelemedeki modele oldukça yakın performans sergiliyor. Kutu içeriği biraz kırpık fakat rengi gri. S12A kanat yapıs ve kullanım itibariyle kasa fanı olarak tasarlanmış ve bundan dolayı diğer modellere göre statik basıncı düşük kalıyor. Eğer bu fanı tercih ederken radyatör ve işlemci soğutucu blokları yerine kasa içerisinde hava sirkülasyonu sağlaması için görevlendirin. Diğer dikkatimi çeken husus ise normalde başka fanlarda olan hava akımından kaynaklı olan ses S12A-PWM modelinde mevcut değil. Detaylı düşününce fanla ilgili olumsuz bir detay aklıma gelmiyor ama illa kulp takılacaksa fiyatı ve rengi sayılabilir. Renk beğenilmezse alternatifler mevcut, fiyat olarak evet yüksek fiyatlı ama kur bu seviyedeyken ben normal karşılıyorum. NF-S12A PWM sessiz kasa fanı isteyen herkese rahatlıkla önerebileceğim bir çözüm.

Los ventiladores Noctua se caracterizan siempre por el color marrón y crema, aunque han lanzado otros colores como el negro o gris, estos se han convertido en seña de identidad. A muchos les gustará y a otros muchos les parecerán poco llamativos para poner en su torre. Si eres de los que pone por encima la estética quizás estos Noctua NF no sean para tí, pero si lo que de verdad te importa es tener unos ventiladores ultra silenciosos y con un gran flujo de aire que mantenga a tu torre más fresca que con ningún otro ventiladores estos cumplen como pocos.

Las pruebas realizadas fueron, poner el equipo al 100% durante 10 minutos en diferentes modalidades, usando para ello el ventilador con PWM, para usar el control de la placa base, y uno de los otros dos ventiladores, ya que tienen el mismo conector de 3 pines, variando únicamente los conectores. Estos ventiladores están situados en la parte de atrás del ordenador para extraer el calor producido por el disipador de la CPU que está al lado de este.
Para ello, usamos el programa Aida64 y comparamos los resultados de los ventiladores con uno estándar del mismo tamaño, usando éste como control. En la siguiente gráfica, podemos ver las diferencias de temperatura y revoluciones de las 3 pruebas, la de control con respecto a los otros dos ventiladores.

NF-S12A PWM Opinión
The Noctua NF-S12A has a lot of flexibility. It offers an excellent balance between acoustics, performance and sturdiness. You are able to tweak the rpm therefore setting your own preference ratio for the sound reduction and fan speed. There is also an extensive Noctua accessory bundle for each of the three fan which gives the user a lot more flexibility than they already have.
Noctua competes with the top brands in the market and yet manages to deliver one of the best. Every new release improves upon the former. The fans have been a lot quieter and have raised the airflow while still being able to retain the same RPMs. Despite the differences being minimal, it still hands down better than other alternatives.
The technology is also quite fascinating, despite operating at the fan’s slowest rpms, it still manages to keep the processor at a good temperature. And if you compare it to other brands, at top speed, Noctua’s NF-S12A fans are still noticeably quieter. Not to mention it runs with less than half of the power of its competitors.
On top of all this, we are given a 6 year manufacturer’s warranty giving the fans excellent support.

It is thus recommended to clean your fans 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 don’t use a vacuum cleaner as this may apply excessive force to the fan.
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.
My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?
- 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.

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.

Can Noctua fans be used to replace noisy stock fans in NAS devices?
Noctua fans such as the 40, 60, 80, 92 or 120mm NF-A series models are ideal for replacing noisy stock fans in NAS devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their NAS units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their NAS device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing NAS fans are:
- Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some NAS units use different assignments. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your NAS device uses the same pin assignment as standard fans. Experienced users may also change the pin assignment by cutting and resoldering the fan cables, but please note that this will void your Noctua manufacturer’s warranty.
- Different pin functions: Noctua fans use the standardised pin functions for PC fans (see this FAQ for details); however, some NAS units use fans where certain pins serve a different function. For example, some devices use the RPM pin for “power good” signals. Therefore please carefully verify that your NAS device uses the same pin functions.
- Firmware speed control: Some NAS devices demand a certain maximum or minimum fan speed. If the new fan doesn’t have the same or similar maximum or minimum speed, the device may display errors or even shut down.
- Different starting voltage: Most NAS devices use voltage-based speed control. If the new fan has a higher starting voltage than the original fan, it may not start up right away. This may lead the NAS device to display errors or even shut down because it suspects a fan failure.
- Different power draw: Some NAS devices monitor the fan’s power draw. If the new fan has a lower power consumption than the stock fan, the device might display errors or even shut down.
Please note that most NAS manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. For example, there are excellent video tutorials available for changing the fans in popular Synology NAS models (DS416j, DS1515+ and DS1812+ in English, DS416/DS415/DS916/DS216/DS214 and DS1515+ in German). Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer. As a result, it is important to make sure that the information or guidelines you rely on when replacing your NAS fan are applicable to your specific model as well as your specific hardware and firmware revision.
Due to the possible issues listed above, Noctua recommends that only experienced users attempt to replace their NAS fans. Please note that since there are so many different NAS models and most of them lack documentation for aspects such as fan compatibility and control, Noctua customer support cannot assist you with compatibility issues when replacing NAS fans. Please contact your NAS manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control.
Can Noctua fans be used to replace noisy stock fans in switches, routers or other network devices?
Noctua fans such as the 40, 60, 80 or 92mm NF-A series models are ideal for replacing noisy stock fans in switches, routers and other network devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their network device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing pre-installed fans are:
- Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some network devices use different assignments. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your device uses the same pin assignment as standard fans. Experienced users may also change the pin assignment by cutting and resoldering the fan cables, but please note that this will void your Noctua manufacturer’s warranty.
- Different pin functions: Noctua fans use the standardised pin functions for PC fans (see this FAQ for details); however, some network devices use fans where certain pins serve a different function. For example, some devices use the RPM pin for “power good” signals. Therefore please carefully verify that your device uses the same pin functions.
- Firmware speed control: Some network devices demand a certain maximum or minimum fan speed. If the new fan doesn’t have the same or similar maximum or minimum speed, the device may display errors or even shut down.
- Different starting voltage: Most network devices use voltage-based speed control. If the new fan has a higher starting voltage than the original fan, it may not start up right away. This may lead the device to display errors or even shut down because it suspects a fan failure.
- Different power draw: Some network devices monitor the fan’s power draw. If the new fan has a lower power consumption than the stock fan, the device might display errors or even shut down.
Please note that most network device manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer.

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?
How can I check if my 4-pin fan header supports PWM?
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.
How big is the NH-D15S and how much clearance does it provide for RAM and mainboard heatsinks? Copy
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!
How should I clean my Noctua fan?
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 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).
