La Galardonada serie NH-U

La Galardonada serie NH-U

El NH-U14S es el primer modelo de 140 mm de la galardonada serie NH-U de Noctua. La serie NH-U, que fue presentada por primera vez en 2005, se ha convertido en una elección habitual en disipadores de CPU silenciosos de gran calidad y ha recibido más de 400 premios y recomendaciones de los principales sitios web y revistas internacionales especializadas en hardware.
Completa compatibilidad con memoria RAM en LGA2011

Completa compatibilidad con memoria RAM en LGA2011

El NH-U14S con un diseño de 52 mm está hecho a medida para el zócalo LGA2011 y no sobresaldrá por encima de las ranuras RAM en esta plataforma, garantizando así una completa compatibilidad con todos los módulos de memoria. En algunas placas base LGA115x y AMD el ventilador frontal puede sobresalir por encima de la primera ranura de memoria RAM, por eso, cuando resulta necesario usar esta primera ranura, hay que elegir memoria RAM de altura estándar (de hasta 30mm).*
Tamaño razonable para mejor compatibilidad global

Tamaño razonable para mejor compatibilidad global

Con 165 mm de alto, el NH-U14S es lo suficientemente pequeño como para encajar en la mayoría de las cajas de alta gama modernas. El NH-U14S de 150 mm de ancho (incluyendo el ventilador y sus ganchos) proporciona mejor compatibilidad con instalaciones SLI y CrossFire comparando con disipadores de torre cuyo ancho es mayor a 150 mm o con los que usan ventiladores de más de 150 mm.

NH-U14S Opinión

Les performances sont au rendez-vous, le processeur est convenablement refroidit. Il refroidit même mieux le NH-C14S. De ce fait, le ventirad de Noctua se place dans le haut du panier avec un processeur à 29°C au repos et 50°C sous OCCT ! Les ventilateurs sont inaudibles en IDLE avec une vitesse de rotation de 400 tours/minute et 900 tours/minutes en OCCT.
Resultado del análisis: "Noctua propose encore un fois un ventirad sans faux pas. Avec cette version, Noctua propose un ventirad alliant de très bonnes performances avec compatibilité quasi illimitée. Il est donc possible avec celui-ci de monter une configuration sans compromis avec un overclock plus que satisfaisant." (Batiste Hocq, Syndrome-OC.net)

NH-U14S Opinión

Just like most big brothers do, the NH-U14S kicked the NH-U12S out of the ball game, not by much though. The difference between the two is that of a couple degrees. Something possibly to keep in mind when playing with your budget.
Resultado del análisis: "Just the same as the NH-U12S, there is not much we don’t like about the NH-U14S, this is one solid CPU Cooler! For this and more, we proudly award Noctua, the NH-U14S with another Editors Choice Award!" (Chris Jolliffe, TechnologyX.com)

NH-U14S Opinión

W połowie maja otrzymałem do testów cztery chłodzenia procesora od firmy Noctua. Dwa tańsze i dwa droższe modele (NH-L9i, NH-L9A, NH-U12S oraz NH-U14S). W tej recenzji opiszę każdy z nich oraz podam wyniki testów pod obciążeniem oraz w spoczynku.
Resultado del análisis: "Ostatnim modelem jest NH-U14S. To najwydajniejszy system chłodzenia w tym zestawieniu. Za utrzymanie temperatury odpowiada 14-centymetrowy wentylator, który sprawuje się bardzo dobrze. Wykonanie stoi na bardzo wysokim poziomie, więc poza ceną, nie mam się do czego przyczepić."

NH-U14S Opinión

Podoba mi się praca wentylatora NF-A14. Preferuję 140 mm, gdzie nawet przy wysokich obrotach, pełnym obciążeniu procesora szum jest niskich częstotliwości: nie drażni i nie bzyczy. Łożyska nie terkoczą, nie słychać też ich ślizgu. Z metra od otwartej obudowy, podczas gdy wentylator kręcił się na maksimum obrotów, zmierzyłem 38,6 dBa przy poziomie ciszy wynoszącym około 30 dBa. Zamknięta obudowa Fractal Design Define S wytłumiła hałas o ponad 2 dBa. Mimo że w pomiarach U14S był głośniejszy od U12S o 1-2 dBa, to wentylator NF-F12 z U12S trochę bardziej przeszkadzał – jego szum był mniej przyjemny dla ucha. W praktyce wentylator NF-A14 z U14S rzadko się rozpędza i nie słychać go w normalnej pracy, a w grach nie przebija przez hałas GPU.
Resultado del análisis: "NH-U14S nie zawodzi pod względem jakości wykonania, wygody montażu, wydajności i kultury pracy – wiadomo, za co się płaci. To nie wybór tam, gdzie liczy się spójny wygląd, odpowiedni motyw kolorystyczny, wtedy w grę wchodziłaby wymiana wentylatora. Wrażenie robi także wydajność zbliżona do dwuwieżowego NH-D15S."

NH-U14S Opinión

Queremos hacer hincapié en lo silenciosos que pueden llegar a ser estos ventiladores y o bien que son capaces de disipar el calor, que con apenas muchas revoluciones en los ventiladores tendremos un optimo funcionamiento de nuestros procesadores. La verdad que Noctua siempre nos sorprende con estos dispositivos, y se nota mucho el mimo que le ponen a estos productos que a nosotros a los que nos gusta tener el mejor rendimiento en nuestro PC, y por otro lado el buen material que usan para fabricarlos. El NH-U14S y el NH-U12S son muy similares de precio, 68€ para el 140mm y 59€ para el de 120mm. Comparando estos dos, el NH-U14S sale ganando por tanto el rendimiento que ofrece como por lo silencioso que es en comparación con el 120mm.
Resultado del análisis: "En definitiva, estos dos disipadores son de lo mejorcito que nos podemos encontrar (salvando distancias con la refrigeración liquida), si queremos mantener nuestra CPU fresca y con una buena ventilación en nuestro equipo." (Ignacio Merino Arnaiz, TecnoGeekies.com)

Most case manufacturers provide specifications for maximum CPU cooler height/clearance. Please refer to these specifications in order to verify that the cooler will fit the case. If no specifications are available, please contact the case manufactuer or measure the distance from the motherboard tray to the side panel (tower cases) or top panel (desktop cases). If this distance is bigger than the height of the cooler + 15mm (mainboard spacers + mainboard + CPU), the height/width of your case should be sufficient.

I can't open the socket due to the mounting bars!

Please first loosen one of the two thumbscrews that hold the mounting bars in place. Then untighten the second screw so that you can swivel the mounting bar and open the socket. Depending on the position of the mounting bars, you may need to swivel both.

Does the package include a backplate for AMD AM2(+)/AM3(+)/FM1/FM2(+)?

No. As most AMD mainboards come with a stock backplate preinstalled, the cooler doesn’t include an AMD backplate. If your mainboard doesn’t have a backplate, please contact our support team at support@noctua.at.

amd backplate

How can I check whether my AMD mainboard has a standard AMD backplate that’s compatible with the SecuFirm2™ mounting system and how should I proceed with the installation?

The SecuFirm2™ mounting system requires a standard AMD backplate (either plastic or metal) with screw threads as shown on the pictures below. These backplates are pre-installed on the rear side of most AMD mainboards (see first picture below) and fixed to the retention module with four screws (see second picture below). If your retention module is fixed with plastic bolts instead of metal screws, please contact support@noctua.at in order to obtain an appropriate backplate.

In order to proceed with the installation of your Noctua cooler, please remove the four screws and the retention module but keep the backplate in place so that you can see the screw threads from the top side of the motherboard (see third picture below). You can then proceed with the installation of the SecuFirm2™ mounting kit as described in the manual (see fourth picture below).

I get a CPU fan error using my Noctua PWM fan, is it faulty?

Noctua PWM fans feature a minimum speed of 300rpm to allow for ultra quiet operation when your CPU is at idle state and doesn’t require higher cooling performance. Some mainboards display error messages such as “CPU fan error” during the booting process when the fan speed is below a certain level. If you get such error messages using your Noctua PWM fan and if such options are available in your BIOS, please either adjust the minimum fan speed monitoring limit to 200rpm or increase the minimum PWM duty cycle. If your BIOS doesn’t offer these options, please disable CPU fan errors. For detailed information on BIOS fan settings, please consult your mainoard’s manual or contact your mainboard manufacturer.

Does the mounting-system support LGA2011 based Xeon CPUs?

There are two different types of ILM (Independent Loading Mechanism) for Intel’s LGA2011 based Xeon CPUs: Square ILM with 80x80mm hole spacing and Narrow ILM with 56x94mm hole spacing. The Square ILM socket is mechanically identical to the LGA2011 socket for Core i7, so the mounting-system is fully compatible, but it is not compatible with Xeon mainboards that use the Narrow ILM:

Xeon Compatibility

How should I clean my Noctua cooler?

Dust: Fans and heatsinks inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fan and heatsink regularly. For cleaning, please first remove the fan from the heatsink and clean it 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. Please also 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. Before reinstalling the fan, clean the heatsink itself with a duster or vacuum cleaner. Do not use water to clean the cooler. Finally put the fan back on and connect it to your motherboard fan header or fan controller.
Thermal paste residues: Whenever you take off the heatsink from the CPU, we recommend to clean the CPU as well as the base of the cooler before re-applying thermal paste and re-installing the cooler. You can either just wipe the base and the CPU clean with a dry, lint-free tissue or, for more thorough cleaning, use a lint-free tissue moistened with either a mild solution of washing-up liquid or isopropyl alcohol. Do not put the cooler or CPU under running water. Note that both the base of the heatsink and the CPU should be dry, free from residues of thermal compound and free from grease before re-applying thermal paste and re-installing the cooler.

Is the cooler compatible with AMD FM2+?

As the hole spacing for CPU cooler installation on FM2+ is the same as on AM2, AM2, AM3(+), FM1 and FM2, the cooler is fully compatible with FM2+ out of the box and doesn’t require any modifications or upgrades.

¿Qué disipadores de Noctua son compatibles con el socket LGA1150?

El montaje es idéntico en todos los sockets LGA115x (LGA1150, LGA1155, LGA1156). Los siguientes disipadores son compatibles con el LGA1150 y no necesitan ningún tipo de actualización para utilizarlos en esta plataforma: NH-C12P SE14, NH-C14, NH-D15, NH-D14, NH-L12, NH-L9i, NH-U14S, NH-U12S, NH-U12P SE2, NH-U9B SE2. Además, todos los modelos anteriores que se hayan actualizado con el kit NM-I3 pueden utilizarse en el LGA1150 sin tener que volver a actualizarlos.

Los siguientes disipadores pueden ser compatibles con el LGA1150 si se utiliza el kit de actualización NM-i115x y son adecuados para el kit de montaje gratuito de Noctua: NH-C12P, NH-U12, NH-U12F, NH-U12P, NH-U12P SE1366, NH-U9, NH-U9F, NH-U9B.

Los siguientes disipadores pueden ser compatibles con el LGA1150 si se utiliza el kit de actualización NM-i115x pero no son adecuados para el kit de montaje gratuito de Noctua: disipadores de la serie DX para Xeon, NH-D14 SE2011.

Los siguientes disipadores son mecánicamente incompatibles con el kit de actualización NM-i115x y no son compatibles con el LGA1150: disipadores de la serie DO para AMD Opteron, NH-L9a.

How big is the NH-U14S and how much clearance does it provide for RAM and chipset coolers?

Please refer to the following drawing for the exact measurements and clearance for RAM and chipset coolers:

U14S

Why is the cooler’s contact surface slightly convex?

As the Integrated Heat Spreaders (IHS) of today’s CPUs are slightly concave, the cooler’s contact surface has been deliberately designed to be slightly convex in order to ensure optimal contact. This way, more contact pressure will be applied at the centre of the IHS directly above the DIE, which results in better heat transfer and improved overall performance.

Is the cooler compatible with LGA775 and LGA1366?

The cooler does not support LGA775 and LGA1366 out of the box, but can be made compatible using the NM-I3 mounting kit. Noctua provides the NM-I3 kit free of charge if a proof of purchase (scan, photo or electronic copy of the invoice) of the cooler and an LGA775 or LGA1366 motherboard or CPU are presented. In order to install the cooler using the NM-I3 kit, please first unscrew the center screw of the original one-piece fastening bracket (you can reach through the fin stack using the long screw driver supplied with the cooler) and remove it. Then install the two fastening brackets of the NM-I3 kit as described in the NM-I3 installation manual.

I’ve used all the NT-H1 thermal compound that came with the cooler, can you send me more?

Please kindly note that the NT-H1 thermal compound supplied with our coolers is a consumable item so our manufacturer’s warranty does not include providing additional thermal compound. You can purchase NT-H1 from our resellers.

Which sockets are supported or can be supported using upgrade kits?

Please refer to our socket compatibility chart.

How can I determine which backplate revision I’ve got?

Please refer to following drawing for how to identify the different backplate revisions:

backplate revisions

Some mainboards pose compatibility problems with the first version of the NM-IBP2 backplate included with the cooler. Please verify to use a revision 1.5 or revision 2 backplate when installing the cooler on these mainboards. All coolers manufactured since April 2013 already include the new revision backplates. Owners of coolers with rev. 1 backplates can request a new backplate from Noctua’s customer service free of charge.

Is the cooler compatible with the LGA2011-3 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA2011-0 and 2011-3, the cooler supports both types of LGA2011-3.

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:

4 pin fan header types

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:

  1. 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.

  2. 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.

  3. 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:

  1. 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.

  2. 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:

    4 pin fan header types

    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.

What Thermal Design Power (TDP) is this cooler recommended for and how much Watt (W) of heat can it dissipate?

Please refer to our TDP guide for information on maximum recommended TDP and heat dissipation.

Can I install a Noctua cooler in my system from Acer, Dell, HP or Lenovo?

Systems from Acer, Dell, HP or Lenovo often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can led to compatibility issues with coolers that where built to comply with these specifications.

Even in case the cooler is mechanically compatible and can be installed, other issues can occur, e.g. proprietary fan connectors, BIOS errors due to a low fan speed, shutdowns, etc. Some of these problems can be avoided with some technical knowledge, but especially BIOS related can often not be resolved.

Due to the large number of possible issues with systems from Acer, Dell, HP and Lenovo, which can't be resolved with different mounting parts alone, Noctua does not officially support such machines.

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 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 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, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

Is the cooler compatible with the LGA1151 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA1150, LGA1151, LGA1155 and LGA1156, the cooler also supports LGA1151.

Why doesn't the supplied backplate fit my LGA2011 motherboard?

The supplied backplate is for LGA115x only and there is no backplate required for installation on LGA2011. Please refer to the installation manual for how to install the heatsink on LGA2011.

My case supports CPU coolers of up to XXXmm height, which model should I choose?

Please refer to our TDP guide in order to select the cooler that offers the best cooling performance at a given height.

How to remove the base protection cover?

Noctua CPU coolers are shipped with a plastic protection cover at the bottom side of the cooler, which protects the contact surface against scratches and other damage.

The base of Noctua CPU coolers is made from hard-wearing nickel plated copper, so there's nothing to worry about if you buy a Noctua cooler from second hand or if your cooler didn't come with a protection cover. Please proceed with the installation as explained in the manual.

You can simply remove the cover as shown below:

I have difficulties installing the cooler, can you help?

Please refer to the installation manual and our video installation guides for detailed instructions on how to install the cooler.

Should I take the cooler off before transporting my system?

As it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, for safety reasons, taking the cooler off. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the heatsink installed.

Can I install a 140mm fan with a square frame (e.g. NF-A14)?

Yes, fan clips for installing square frame 140mm fans (such as the NF-A14) are available on request via our customer support.

Are there any concerns using Noctua CPU coolers on Intel Skylake (LGA1151) CPUs?

Our SecuFirm2™ mounting systems undergo comprehensive compatibility tests before being approved for new platforms. We have neither detected any problem with regard to the Intel LGA1151 platform (“Skylake”) during these tests nor have we received any reports from our customers, sales partners and system integrators that would indicate any possible issue. Our SecuFirm2™ mounting systems (with the exception of some compact L-type models) rely on coil springs to create the required contact pressure, which gives a certain flexibility both with regards to tolerances in stackup height and shocks or other forces. Compared to spring-less mounting systems, which exclusively rely on the bending of the mounting brackets in order to create contact pressure, this allows to reduce the mechanical stress on CPU, socket and motherboard and thus helps to prevent possible damage from excessive forces. However, as it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, due to safety reasons, to take off coolers with a total weight of more than 700g (incl. fan).

Does the NF-A15 PWM that comes with Noctua coolers run at a different speed (1500rpm) than the retail model (1200rpm)?

Yes, the NF-A15 PWM bundled with our heatsinks is specified to run at 1500rpm (see cooler specifications for details) and the retail model is specified to run at 1200rpm (see fan specifications for details). The 1200rpm retail model is ideal for setting up push/pull configurations in combination with the coolers’ 1500rpm stock fan because the combination of the 1500 and 1200rpm models provides a better balance of performance and noise than the combination of two 1500rpm versions. On dual-tower coolers such as the NH-D15S, we recommend to run the 1500rpm version in the center and the 1200rpm version on the front. On single-tower coolers such as the NH-U14S, we recommend to run the 1500rpm version on the front and the 1200rpm version on the back of the cooler. The NA-YC1 y-cable supplied with the retail fan can be used in order to control both fans via one PWM fan header. In this case, both fans will scale individually according to the PWM duty cycle supplied by the motherboard, e.g. they will run at ~1500/1200 respectively at 100% duty cycle, ~750/600rpm at 50% duty cycle, etc. Both at 100% and lower speeds, the speed difference between the fans reduces resonance phenomena and thus helps to achieve the best balance of performance and noise.

Is it a problem that the CPU heatspreader is not covered completely by the heatsinkbase on LGA2011-3?

No. Depending on the orientation of the cooler, 1-2mm at the outer edge of the heatspreader may not be covered by the heatsink base. As the heat is concentrated at the center of the CPU and the outermost parts are irrelevant for heat-transfer, this is no problem at all.

¿Por qué la base de los disipadores Noctua no tiene un acabado pulido como un espejo?

Teniendo en cuenta que mayoría de los entusiastas del hardware usan compuestos térmicos de alta viscosidad, la superficie de la base de los disipadores Noctua se ha optimizado para el uso de este tipo de pastas térmicas. Las micro-hendiduras de la superficie de la base de los disipadores Noctua aseguran que los compuestos térmicos de alta viscosidad se dispersen de manera uniforme en una fina capa por toda la zona de contacto y que no queden huecos entre el disipador y la CPU. Con un acabado pulido como un espejo, el riesgo de una dispersión desigual es mucho más alto. Dado que las capas demasiado gruesas de pasta térmica y los huecos con aire deterioran dramáticamente la transferencia térmica, las micro-hendiduras son de vital importancia en el rendimiento general de los disipadores Noctua cuando se usan con compuestos térmicos de alta viscosidad.

The supplied y-cable is missing a wire at one of the two connectors, is it faulty?

No. As mainboards can process only one rpm-signal per fan header, it would cause problems if the cable transmitted rpm-signals of both fans. For this reason, one of the two connectors does not have an rpm wire and only the fan on the other connector will transmit an rpm signal. Automatic speed control of both fans will work independent from the second fan’s rpm signal.

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:

Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one?

Most Noctua SecuFirm™ mounting parts are cross-compatible, so if you’re replacing one Noctua cooler with another, it is usually possible to keep the original backplate and/or mounting system in place in order to re-use it for the new cooler. If you had your previous Noctua cooler installed on an Intel LGA115x (LGA1156, LGA1155, LGA1151, LGA1150), LGA2011 (LGA2011-0, LGA2011-3) or LGA1366 system and replace it with an NH-U14S, NH-U12S or NH-U9S, you only need to replace the original mounting bars with the NM-IMB3 ones supplied with the new cooler. For all other models, you can keep the entire mounting system in place on the aforementioned Intel sockets. On AMD AM2, AM2+, AM3, AM3+, FM1, FM2, FM2+, you only need to replace the original mounting bars with the ones supplied with the new cooler.
