Fuera de producción. Modelo sucesorio: NH-U9F

Gracias a 4 Heat-Pipes duales, 37 aletas de aluminio con una superficie total de refrigeración de más de 3800cm² y uniones soldadas para una óptima transferencia térmica, el Noctua NH-U9 logra un rendimiento de refrigeración superior que apenas están un paso por detrás de su hermano mayor, el NH-U12. Sus dimensiones compactas y la utilización de ventiladores de 92mm hacen que el NH-U9 sea la primera elección cuando asegurar la compatibilidad con la caja y la placa base sea esencial. - ¡ya sea para conseguir el máximo silencio, o una refrigeración ultra-eficaz!

4 Heat-Pipes duales para una óptima absorción térmica.
Los 4 Heat-Pipes duales en forma de U tienen una enorme superficie de contacto con la base de cobre para absorber eficientemente el calor de la CPU. Forman 8 conductos que se elevan para distribuir el calor entre las aletas.

37 aletas de refrigeración fabricadas en aluminio para una óptima disipación térmica.
Gracias a la superficie de más de 3800cm², las aletas de refrigeración disipan el calor extremadamente rápido. Tanto la elección del aluminio como la forma de las aletas y su espaciado, logran una refrigeración con un rendimiento sobresaliente, incluso con ventiladores silenciosos.

Uniones soldadas para una óptima transferencia térmica.
Al contrario que otros disipadores, cuyos Heat-Pipes están pegados a la base y a las aletas, el Noctua NH-U9 posee uniones soldadas de alta calidad para asegurar una óptima transferencia del calor.

Montaje del ventilador sin herramientas y tiras anti-vibración incluidas.
La elección del ventilador es toda tuya.: los ventiladores de 120mm ofrecen excelentes resultados, sin importar que tu principal objetivo sea el silencio o el rendimiento. Colocar el ventilador usando los clips de acero es un juego de niños, y ni siquiera necesita un destornillador. Las tiras anti-vibración incluidas minimizan las vibraciones que se transmiten al disipador, y por lo tanto permiten un funcionamiento aún más silencioso.

Montaje universal para socket LGA y K8 & AM2, fácil instalación, pasta de transferencia térmica.
El NH-U12 es compatible con el socket Intel LGA 775, así como con el AMD K8 y AM2.

The Noctua NH-U9 performed well under pressure, posting a two degree difference in idle temps and a fantastic five degree difference in load temps over its stock configuration. Not only that, but we also managed to gain another 22 MHz (2 MHz HTT) on our overclock. Despite the difference between the NH-U9 and its big brother, the NH-U9 is still a top performer according to our tests.

NH-U9 Opinión

El Noctua NH-U9 es un excelente disipador que, incluso con el ventilador menos potente, mejora en 1ºC la temperatura del Thermalright XP-120 equipado con el muy potente Silverstone FM-121. Equipado con un ventilador más potente, la diferencia se agranda, llegando a ser de 5ºC en la prueba de overclock extremo (1,65V en el núcleo es el voltaje a partir del cual ya te empiezas a plantear poner una refrigeración líquida). Lo que no cuentan las cifras es lo increiblemente silencioso que es este disipador incluso equipado con el ventilador SwiF-922 que es más potente que el SwiF-921. Es tan silencioso que la primera vez que lo conecté pensé que no se había encendido el ventilador porque, simplemente, no lo oía. Por tanto, altamente recomendado, incluso para overclocks moderados.
Resultado del análisis: En resumen: Estos disipadores me han dejado completamente anonadados con sus resultados. Silencio y prestaciones, todo en un mísmo paquete... Y parecía imposible!

Les résultats obtenus en passif sont tout simplement bluffant! En particulier pour le NH-U12 qui dépasse à peine 42°C en burn, mais le U9 obtiens quand même un delta de seulement 11°C ce qui nous donne en burn une température de 47° ce qui est tout à fait acceptable. Le NH-U12 révèle tout son potentiel quand il est couplé avec deux ventilateurs Coolink et le tout dans un silence plus qu?appréciable.

Der NH-U9 und sein großer Bruder, der NH-U12, spielen in Sachen Verarbeitung und Vielseitigkeit ganz klar in der Oberklasse mit. Das durchdachte Befestigungssystem ermöglich in Verbingung mit der ausführlichen Montageanleitung eine sichere und einfache Montage und man kann den PC sogar mit montiertem Kühler transportieren, was bei derartig kollosalen Kühlern früher nicht in Frage kam. Auch die Verarbeitung beider Kühler ist makellos. Die Kühlleistung von NH-U9 und NH-U12 ist bei Lüftern mit hohen Fördermengen sehr zufriendenstellend, aber sie zeigen erst bei wenig Luftstrom was wirklich in ihnen steckt.

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.

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.

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.

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.

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.

How much torque should be applied when tightening the screws of a Noctua CPU cooler?

All screws should be tightened gently until they stop without using excessive force. Please do not exceed the following values for maximum tightening torque:
Screw typeMax. torque
NM-SSC1 screws for fixing the fastening brackets to the base of the heatsink0.5 Nm
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

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.

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.

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.

¿Es posible montar ventiladores de altura superior a 25mm?

Sí. Los clips de montaje del disipador se agarran a los agujeros de los tornillos del extremo más bajo del ventilador, y por lo tanto funcionan con cualquier ventilador sin importar su altura. De todos modos, puede haber problemas en la instalación del ventilador si éste tiene un marco de forma especial, donde los clips no puedan agarrarse al extremo inferior del marco.

¿Es posible usar dos ventiladores a la vez?

Sí. Con los 4 clips de ventilador provistos, puedes montar dos ventiladores de 120mm en el NH-U12(F/P) y dos ventiladores de 92mm en el NH-U9(F/B).

¿Cómo debo colocar el ventilador: aspirando el aire del disipador o soplando sobre él?

Por favor coloca el disipador de modo que éste sople aire sobre el disipador.

¿Puedo refrigerar mi CPU sin ventilador (de forma pasiva) usando los disipadores Noctua?

Los refrigeradores Noctua no se diseñaron originalmente para su uso pasivo, aunque su capacidad de refrigeración es suficiente en muchos casos. Desafortunadamente, nos es imposible indicar que CPU concreta puede o no puede refrigerarse sin ventilador, pues depende de varios factores, como la temperatura de la caja, la ventilación o la orientación del socket. Generalmente, recomendamos usar un ventilador en primera instancia, y luego ir bajando las revoluciones de forma constante sin dejar de monitorizar la temperatura.

How to install the fan using the supplied steel clips?

First hook the clip into the notch of the heatsink:

Is the high weight dangerous for the CPU or socket?

No. Los disipadores Noctua poseen un sistema de montaje SecuFirm™ extremadamente fiable. Gracias a la conexión mediante tornillos al backplate de la parte posterior de la placa, el exceso de peso -según las recomendaciones de Inter y AMD- común entre los disipadores de gama alta, no tiene objeción posible.

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.

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. Each processor uses an I/O-Die (IOD), which contains things like the memory controller, PCIe controller, connections to the motherboard chipset and other functions. 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.

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 model, as well as the allowed TDP and power rating, 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 (the amount of heat created per mm², measured inW/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 (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.
