Product discontinued. Successor model: NH-U9F

Thanks to the 4 Dual-Heat-Pipes, 37 aluminium cooling fins with a total surface area of more than 3800cm² and soldered joints for optimal heat-transfer, the Noctua NH-U9 achieves superior cooling results that barely fall behind those of its big brother, the NH-U12. Its compact measurements and the utilisation of 92mm fans make the NH-U9 the first choice when mainboard and case compatibility is essential - no matter whether you use it for super-silent or ultra-high-performance cooling!

4 Dual-Heatpipes for optimal heat absorption
The 4 u-shaped Dual-Heat-Pipes have a huge contact area with the copper base to efficiently absorb the CPU's heat. They form a total of 8 risers to spread the heat throughout the fins.

37 aluminium cooling fins for optimal heat dissipation
Thanks to a surface area of more than 3800cm², the cooling fins dissipate the heat extremely fast. Both the choice of aluminium and the fins' shape and spacing allow for outstanding cooling performance even with silent fans.

Soldered joints for optimal heat-transfer
Unlike many other coolers, whose heat-pipes are stuck to the base and the fins, the Noctua NH-U9 possesses high-grade soldered joints to ensure optimal heat transfer.

Screwless fan-mount including anti-vibration strips
The choice of fan is all yours: Both 80 and 92mm fans can be used on the NH-U9 and provide excellent results regardless of whether silence or performance is your primary concern. Attaching the fan with the steel clips is a child's play and doesn't even require a screwdriver. The supplied anti-vibration strips minimize vibrations transmitted to the cooler and hence allows for extra quietness.

Universal fit for socket LGA, K8 & AM2 easy installation, thermal paste
The NH-U12 fits Intel socket 478 and LGA 775 as well as AMD K8. The mounting mechanism using a backplate and spring-loaded screws is as easy as it is secure thanks to the detailed step-by-step installation guide. In addition to the mounting hardware, the package contains a syringe of high-grade thermal paste.

NH-U9 Review

Als eerste valt ons op dat de Noctua zijn hoofd enorm koel houdt voor een passieve CPU koeler met temperaturen van 28 graden Celcius idle en 32 onder load. De NH-U9 levert zelfs betere temperaturen dan onze stock koeler die de processor terugbrengt naar 35 graden onder idle load en 42 graden onder load.
Test verdict: "De Noctua NH-U9 is een uitstekende koeler." (Kenny Bakermans, Bouweenpc.nl)

NH-U9 Review

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.
Test verdict: "If space is a consideration, the NH-U9 is the best solution we have seen. (William McLaughlin, BleedinEdge.com)

NH-U9 Review

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.
Test verdict: En resumen: Estos disipadores me han dejado completamente anonadados con sus resultados. Silencio y prestaciones, todo en un mísmo paquete... Y parecía imposible!

NH-U9 Review

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.
Test verdict: "J'ai été agréablement surpris par les performances des deux ventirads quelque soit le mode d'utilisation, double ventilation ou passif, les Noctua se révèlent être de très bons dissipateurs.

NH-U9 Review

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.
Test verdict: "Die eingangs gestellte Frage war, ob Noctua es geschafft hat, ein neues Maß an Qualität und Leistung auf dem Markt zu etablieren. Die Antwort lautet: Ja, haben sie." (Finn Schmitz, DeXgo.com)

Is the high weight dangerous for the CPU or socket?

No. Noctua coolers possess an extremely reliable SecuFirm™ mounting system. Thanks to the screw connection with the backplate on the rear side of the motherboard, the exceedance of the weight recommendations by Intel and AMD common among high-end coolers is completely unobjectionable.

Is it possible to mount fans with a greater height than 25mm?

Yes. The fan mounting clips grip to the screw holes in the lower edge of the fan frame and hence work with all fans regardless of their height. However, problems with the mounting of the fan can occur due to other parts within the case or fans with special frame designs, where the clips can't grip to the screw holes in the lower edge of the frame.

NH-U fan mounting

Is it possible to run two fans at a time?

Yes. Using the 4 supplied fan clips, you can mount two 120mm fans on the NH-U12(F/P) and two 92mm fans on the NH-U9(F/B).

Should the fan be mounted sucking away from the heat-sink or blowing onto the heat-sink?

Please install the fan blowing onto the heat-sink.

NH-U Airflow

If you're using two fans, please install them so that one blows onto the heat-sink and the other sucks the air away from the other side.

On which side of the heat-sink should the fan be installed?

Please install the fan so that the hot air can be disposed as good as possible either through the rear case fan (Airflow Option 1) or through the power supply (Airflow Option 2).

Is it possible to cool my CPU without a fan (passive) using Noctua coolers?

Noctua coolers weren't originally designed for passive operation although the cooling performance is sufficient in many cases. Unfortunately, it is impossible for us to indicate whether a certain CPU can or cannot be cooled without a fan, as this depends on various factors such as case temperature, case ventilation or the orientation of the socket. Generally, we recommend using a fan in the first instance and then lowering RPM while constantly monitoring the temperature.

How to install the fan using the supplied steel clips?

First hook the clip into the notch of the heatsink:

Then hook the endings of the clips into the mounting holes of the fan:

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.

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 TDP guide for information on maximum recommended TDP and heat dissipation.

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

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 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.

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.
