Perfil bajo de 37 mm

Gracias al disipador de solo 23 mm y al ventilador de bajo perfil NF-A9x14, cuyo grosor es de solo 14 mm, el NH-L9 tiene una altura de solo 37 mm, lo que lo hace perfecto para su uso en HTPC compactos o cajas con un factor de forma reducido que ofrecen un espacio mínimo para los disipadores de CPU.
100 % de compatibilidad con RAM

100 % de compatibilidad con RAM

El NH-L9i tiene unas dimensiones de 95 x 95 mm que cumplen exactamente con el espacio de precaución alrededor del socket Intel LGA115x. Esto implica que no provocará problemas con los disipadores del chipset y no colgará por encima de las ranuras de la RAM, por lo que es completamente compatible con los módulos de gran tamaño.
100 % de compatbilidad con tarjetas gráficas en mini-ITX

100 % de compatbilidad con tarjetas gráficas en mini-ITX

La mayoría de placas base mini-ITX basadas en Intel LGA 115x sitúan la ranura PCIe junto a la zona del socket de 95 x 95 mm. Mientras que los disipadores de mayor tamaño que superan el de esta zona pueden bloquear la ranura PCI-E, el NH-L9i, gracias a sus dimensiones de 95 x 95 mm proporciona total compatibilidad con las tarjetas PCIe.
Ventilador de primera calidad NF-A9x14 PWM

Ventilador de primera calidad NF-A9x14 PWM

El ventilador de primera calidad NF-A9x15, altamente optimizado, cuenta con el marco AAO exclusivo de Noctua, así como con sofisticadas medidas de diseño aerodinámico. Compatible con PWM para un control de velocidad completamente automático, el NF-A9x14 permite al NH-L9i permanecer notablemente silencioso.
Adaptador para reducción del ruido

Adaptador para reducción del ruido

Al permitir la reducción de la velocidad máxima del NF-A9x14 de 2500 a 1800 rpm, el adaptador para la reducción del ruido (LNA) permite lograr instalaciones casi silenciosas, con CPU cuyo TDP es inferior a 65 W.

Compuesto térmico NT-H1

Compuesto térmico NT-H1

El aclamado NT-H1 de Noctua es una solución térmica de nivel profesional que proporciona una resistencia térmica mínima, gran facilidad de uso y una destacada fiabilidad. Se ha establecido como una referencia entre los compuestos térmicos de gran calidad ya que es uno de los más elegidos entre los overclockers y aficionados de todo el mundo.
Interfaz de soldadura entre heatpipes y aletas

Interfaz de soldadura entre heatpipes y aletas

En muchos disipadores las aletas se unen con presión a los heatpipes. Debido a los diferentes coeficientes de expansión térmica del cobre y del aluminio, esta unión podría soltarse con el paso de los años, lo que provocaría una disminución del rendimiento. En cambio, las aletas del NH-L9i están soldadas a los heatpipes para garantizar una interfaz térmica de mayor calidad que no se deteriore incluso tras varios años de uso.
6 años de garantía del fabricante

6 años de garantía del fabricante

Los productos de Noctua son reconocidos por su impecable calidad y destacada longevidad. Al igual que el resto de ventiladores Noctua, el NF-A9x14 incluido ofrece un tiempo medio de vida entre fallos (MTBF) de más de 150 000 horas, y todo el conjunto del NH-L9i viene con una garantía total del fabricante de 6 años.

NH-L9i chromax.black Opinión

Nous avons photographié chacun des trois modèles sous tous les angles, à la recherche de la moindre imperfection. Nous avons fait “chou blanc”… Le noir envahit la totalité du ventirad, jusqu’aux petits circlips maintenant les vis montées sur ressort. La finition est excellente et l’on n’en attendait pas moins de la part de Noctua. Seule la base cuivrée du radiateur revêt son placage nickelé. On constate que même les accessoires du système de fixation revêtent cette couleur. Un noir d’aspect satiné habille donc trois ventirads, Noctua ayant sélectionné trois modèles représentatifs des différents formats. Le NH-D15 chromax.black, vaisseau amiral de la flotte autrichienne, doté d’un radiateur au format double tour et accompagné de deux ventilateurs. Le NH-U12S chromax.black qui représente le ventirad doté d’un radiateur au format simple tour et accompagné par un seul ventilateur. Le NH-L9i qui représente le format Top Flow.
Resultado del análisis: "Vous aimez les performances des ventirads issus de la marque Noctua, mais… Mais, vous ne pouvez franchir le pas en raison des couleurs spécifiques à cette marque. Cette époque est maintenant révolue !" (Bertrand Curras, modding.fr)

NH-L9i chromax.black Opinión

Оригинальная Noctua NH-L9i с неокрашенным радиатором и фирменным вентилятором цвета кофе с молоком была выпущена ещё в далеком 2013 году. Все эти годы она являлась отличным выбором для сверхкомпактной системы, и, не просто отличным, но, вероятно, даже лучшим. Появление афро-версии на её статус нисколько не повлияло. [...] Noctua NH-L9i chromax.black – топовый кулер в своих габаритах, который из-за качества исполнения способен потягаться даже с более тяжеловесными моделями. В случае с маломощным процессором, уровень TDP которого порядка 65 Вт, он будет почти бесшумным. С 95-ваттным «камнем» без разгона будет уже чуть шумнее, но только в стресс-тестах. В играх и прочих повседневных нагрузках кулер будет также очень тих. Наконец, процессор даже можно прилично подразогнать, но будьте готовы к температурам под 90 градусов.
Resultado del análisis: "Итого чёрная Noctua NH-L9i строго рекомендуется, но только если на первом месте стоят габариты. В случае полноразмерной сборки будет и холоднее, и тише, и дешевле приобрести обычную «башню». Но как ни крути это “Выбор редакции”." (Ubeiko Oleg, OCClub.ru)

NH-L9i chromax.black Opinión

Noctua NH-L9i is an excellent cooler, which is one of the best options on the market for small form factor computers or HTPC. Considering the size, we can say it performs great and runs quietly. There are not many competitive coolers on the market that could offer as much. The chromax.black version brings a fresh new look to the already popular design. All enthusiasts who are into small computers will be for sure interested in this product. The previous version, even though it is performing about the same, didn’t fit a color scheme of small gaming builds.

NM-ITS1 thumb screws for fixing Intel mounting bars0.5 Nm
NM-ALS1 screws for fixing AMD mounting bars0.6 Nm
Spring-loaded screws for fixing the heatsink to the mounting bars0.6 Nm

How can I determine if the motherboard’s UEFI BIOS is overclocking my processor by default and deactivate this automatic overclocking?

Most motherboard vendors allow their overclocking-enabled products (e.g. those with Intels X- or Z-series chipsets) to run the processor at increased clock speeds by default, without requiring any user action at all. Since TDP (Thermal Design Power) limits are usually also disabled by default, this leads to the CPU exceeding the rated TDP to a varying degree, depending on the used applications and their workloads. Due to the increased heat output of the CPU, you may see higher CPU temperatures than expected.

In order to find out if your motherboard is overclocking your processor by default, please enter the UEFI BIOS and select the “advanced” or “overclocking” menu. There you should be able to find options such as “MultiCore Enhancement” (options: enabled/disabled), “CPU Ratio Apply Mode” (options: all/per core) or similar. To disable the automatic overclocking, adjust the settings either to “disabled” or “per core” and make sure that the individual multipliers match the original specifications.

In doubt, please contact your motherboard vendor for detailed instructions on how to disable this feature.

My Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?

Current processors from Intel, especially the unlocked models with the suffixes C, K, X or XE (e.g. Core i7-8700K, Core i9-7900X oder Core i9-9900K) can dissipate noticeably more heat than indicated by the TDP specification.

While many motherboard models stick to the recommended power levels and clock speeds settings from Intel, there are models where the UEFI BIOS is configured in such a way that:

  1. the TDP limits are extended or disabled.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.

Depending on the load scenario and CPU configuration settings, the actual power draw can be 1.5-3 times as high the stated TDP value. This can lead to temperature issues, especially when using smaller coolers, compact cases or cases with poor airflow, when some applications create very high loads, e.g. Prime95 with AVX2 support, 3D-rendering or simulation software.

The actual power draw of the processor can be monitored with software provided by the motherboard vendor or with 3rd party tools like HWInfo or HWMonitor.

If you encounter temperature issues (>90°C) and notice a higher than specified power draw, please ensure that no automatic overclocking is applied. You might also want to limit the TDP to either the specified value by Intel or a value that is 5-10W below the value previously read out from the CPU. This can be done in BIOS by setting the “Long Term Duration Power” manually instead of “Auto”.

Furthermore, it may also help to lower the CPU clock speed for applications that heavily use the AVX instruction set, which can lead to higher loads and power draw. This option is usually referred to as “AVX offset” and makes it possible to lower the multiplier specifically for AVX based applications without reducing performance when using other instruction sets. Depending on the quality of the CPU and the programs being used, a reduction of 2-3 steps usually gives very good results.

The option to set an AVX-offset value is usually available for the following CPU generations:

  • LGA1151:7th, 8th and 9th generation (Kaby Lake, Coffee Lake)
  • LGA2011-3: 6th generation (Broadwell-E)
  • LGA2066: 7th and 8th generation (Skylake-X)

Please contact your motherboard vendor for details if you have trouble finding the appropriate settings in the BIOS.

All our TDP recommendations are based on thorough testing with the default values specified by Intel using popular applications such as Asus Realbench and prime95. Please note, however, that prime95 creates a particularly high load that goes beyond most typical application scenarios and this leads to elevated temperatures. We thus recommend using other programs such as Realbench for checking the stability and temperatures of the CPU in realistic scenarios.

Please also note that CPUs that use thermal paste instead of soldering between the DIE and the heatspreader generally run hotter. Due to the thermal bottleneck created by the thermal paste, temperatures can be high even at the specified TDP.

Why is my Ryzen 3000 processor getting so hot? Why are Ryzen 3000 CPUs running hotter than previous generation Ryzen CPUs with the same TDP rating? Is there anything wrong with my cooler?

The latest Ryzen 3000 processors (except APU models) differ from previous Ryzen generations in that they are no longer based on a single, large chip but use a multi-chip approach with smaller chips instead. Depending on the exact model there can be one (6 and 8-core models) or two (12 and 16-core models) actual CPU-Dies (CCD) on the package. Each processor also uses an I/O-Die (IOD), which contains things like the memory controller, PCIe controller, connections to the motherboard chipset and other functions.



Because of this design change and the switch to a smaller 7nm manufacturing process, the heat distribution of the overall processor is much different from older 14nm and 12nm based single-chip Ryzen processors with a similar power draw.

Depending on the exact CPU model, its specified TDP value and possibly extended power limits (precision boost overdrive), a single CPU-die can create a heatload of up to 130W easily, whereas the I/O-die usually creates a heatload of about 10W. Due to the small size of the CPU-die, the heat density (W/mm²) of this chip is very high. For example, a 120W heatload at a chip-size of 74mm² results in a heat-density of 1.62W/mm², whereas the same heatload on an older Ryzen processor with a chip-size of 212mm² gives a heat-density of just 0.57W/mm².

This large difference in heat-density is the reason why newer Ryzen 3000 processors become much warmer at similar heatloads than their predecessors.

Furthermore, Ryzen 3000 CPUs are using the rated temperature headroom (up to 95°C) quite aggressively in order to reach higher boost clocks. As a result, it is absolutely no problem and not alarming if the processor runs into this temperature limit. The clock speed and supply voltage will be adjusted automatically by the processor itself in order to remain within AMD’s specifications and to prevent overheating.

Due to the higher heat density, higher thermal limits and more aggressive boost clock usage, it is perfectly normal that Ryzen 3000 CPUs are reaching higher temperatures than previous generation Ryzen CPUs with the same TDP rating. Higher CPU temperatures are normal for Ryzen 3000 processors and not a sign of that there is anything wrong with the CPU cooler.

Does the coating of the chromax.black coolers affect performance?

Thanks to thoroughgoing optimisations of the coating material and process, the chromax.black models provide the same, renowned quiet cooling performance as their regular, non-coated counterparts.

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:

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 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.

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.

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.

Which Noctua fan or CPU cooler should I buy? How to choose the right model?

Not sure which Noctua product to buy? Our detailed buying guides for fans and CPU coolers help you to choose the model that works best for you.

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

Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can lead to compatibility issues with coolers that were 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 issues can often not be resolved.

Due to the large number of possible issues that cannot be resolved with different mounting parts alone, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.

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

Please refer to our CPU compatibility list for information on maximum recommended TDP and heat dissipation.

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

Please refer to our socket compatibility chart.

Can the NH-L9i be used on AM4?

The NH-L9i has been designed for the Intel LGA115x platform. While it can be installed without any problems on most AM4 motherboards using the NM-AM4-L9aL9i kit, it is possible that it may not fit in some cases. Therefore, please be extra careful when installing the NH-L9i on AM4 and verify that the cooler doesn’t press against any other components.

Please also note that there has been a minor revision of the NH-L9i heatsink in April 2013 (see illustration below). Since this revision, the heatsink features a cut-out on one side in order to provide better clearance for tall motherboard components. If you install the cooler on an AM4 motherboard that has tall components close to the socket and if your heatsink has the cut-out, you can orient the cooler in such a way that the cut-out is above the components in order to maximise clearance. Regardless of whether or not your heatsink has the cut-out, please carefully double check that it doesn’t press against any components!

NH-L9i revisions on AM4

Should I take the cooler off before transporting my system?

Due to the low weight of the cooler, it is not necessary to take it off for transport.

The mounting brackets don’t touch the mainboard, is this an issue?

No. The mounting brackets are not meant to touch the mainboard and the flexibility of the brackets is required to create the appropriate contact pressure. There should be up to 3mm (Intel) or 4mm (AMD) space between the mainboard and the mounting brackets when the cooler is correctly installed.

¿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.

¿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.

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.

My unlocked Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?

Intel's unlocked CPUs (K, X and C suffix) can dissipate more heat than indicated by the TDP specification if
  1. the TDP limits are extended or disabled in the motherboards' BIOS.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
  3. some software creates untypical loads, e.g. Prime95 with AVX2 support and a) and/or b) apply.

This can lead to temperature issues, especially when using smaller coolers or compact cases.

The actual power draw of the processor can be monitored with software provided by the motherboard vendor or with 3rd party tools like HWInfo or HWMonitor.

If you encounter temperature issues (>90°C) and notice a higher than specified power draw, please ensure that no automatic overclocking is applied and limit the TDP to the specified value by choosing appropriate BIOS settings.

For Kaby Lake CPUs, it may also help to lower the CPU clock speed for applications that heavily use the AVX instruction set, which can lead to higher loads and power draw. This option is usually referred to as “AVX offset” and makes it possible to lower the multiplier specifically for AVX based applications without reducing performance when using other instruction sets. Depending on the quality of the CPU and the programs being used, a reduction of 2-3 steps usually gives very good results.

Please contact your motherboard vendor for details if you have trouble finding the appropriate settings in the BIOS.

All our TDP recommendations are based on thorough testing with the default values specified by Intel using popular applications such as Asus Realbench and prime95. Please note, however, that prime95 creates a particularly high load that goes beyond typical application scenarios and this leads to elevated temperatures. We thus recommend using other programs such as Realbench for checking the stability and temperatures of the CPU in realistic scenarios.

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.

Which Noctua CPU coolers are compatible with Intel LGA2066?

Due to the heatsink mounting mechanism being identical on LGA2011 and LGA2066, Noctua’s SecuFirm2™ mounting systems for LGA2011 also support Intel’s upcoming ‘Basin Falls’ X299 HEDT (High End Desktop) platform for ‘Skylake-X’ and ‘Kaby Lake-X’ processors. Most current Noctua coolers already include SecuFirm2™ mounting systems for LGA2011 and can thus be used on LGA2066 motherboards without any upgrades or modifications.

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.

Can I upgrade my existing Noctua cooler to socket TR4 or SP3?

Unfortunately, it is not possible to upgrade existing Noctua heatsinks to support the AMD TR4 and SP3 sockets for Ryzen Threadripper (X399) and Epyc CPUs. TR4/SP3 CPUs have much bigger heatspreaders (as compared to e.g. LGA2066 or AM4 processors) and the contact surfaces of standard Noctua heatsinks would cover only about half of these heatspreaders, which would result in insufficient cooling performance. On top of that, the heatpipes of bigger cooler models like the NH-D15 or NH-D15S would completely block the RAM slots on many TR4/SP3 motherboards. For this reason, Noctua has introduced the new NH-U14S TR4-SP3, NH-U12S TR4-SP3 and NH-U9 TR4-SP3 cooler models that feature bigger contact surfaces and have been tailored to fit TR4 and SP3 systems. Please choose these models for AMD Ryzen Threadripper and Epyc systems.

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.

How can I remove the mounting brackets of my NH-L9i chromax.black cooler?

In order to remove the mounting brackets, please put the cooler upside down on a table. Then use a high quality Phillips #2 screwdriver and apply a good amount of pressure to loosen the screws. You can then take off the mounting brackets. Note that loosening the screws and taking off the brackets will require a bit of force due to the black coating.
