NH-U9B Opinión

Amazingly, the little NH-U9B bested almost every heatsink on the chart. It was only a degree or two behind its big brother, the NH-U12P and the Thermalright SI-128 SE. Very good! [...] As we discovered during the last heatsink roundup, Prime95 'Small FFT' testing puts significantly more strain on modern Intel processors than "Large FFTs". The NH-U9B had no issues coping with the extra heat load and kept its position in third. I have to keep reminding myself that this heatsink employs a 92mm fan! There are heatsinks more than twice its weight trailing behind it. [...] With two NF-B9 fans, we were able to match the performance of our reference fan, while still producing far less noise. Those who want high performance while keeping noise at a minimum will be very pleased with a dual NF-B9 configuration.
Resultado del análisis: "Noctua does not disappoint with the NH-U9B. Outperforming almost all of our 120mm heatsinks, it is a phenomenal performer." (Mike D., Icrontic.com)

NH-U9B Opinión

In conclusion, I have to agree with Chris and everything he has told me about this company being true as could be. Noctua coolers not only can do a good job of ridding the CPU of its heat, but do it so quietly that it left me checking to see if the fans were even running. As far as tower style coolers go, with a small form factor in mind this is the quietest cooler I have tested yet. I have to say I am very impressed, to say the least. The well thought out overall design of the cooler doesn’t just stop there. Noctua takes it all the way into the mounting hardware. Noctuas take on getting a CPU to stay in a comfortable range of temperatures, while leaving the surrounding area virtually free of noise puts this cooler high in my list of favorites I have tested.

Seeing how small the NH-U9B is I was pleasantly surprised by the good performance of it, we can see also that even though it looks similar to the NH-U9F, the U9B has much better results, so something significant has changed during the re-design process.
Resultado del análisis: "The NH-U9B is a quality addition to the Noctua line of CPU coolers, don't let its small size fool you, it performs just as good as coolers that are much larger than it." (Kristofer Brozio, DragonSteelMods.com)

The overclocked results tell a similar story with the Noctua cooler way ahead and the extra fan taking off another degree at load, but both results are below 60 at 100% load which is certainly impressive.
Resultado del análisis: "Noctua has impressed us no end here at Verdis Reviews with their consistent high quality and performance coolers. In this regard the NH-U9B is no different achieving some very solid temperatures despite the smaller build making it ideal for HTPCs and other smaller chassis." (Joe Blackmore, VerdisReviews.com)

NH-U9B Opinión

Bueno, el cooler de Noctua se comporta de manera sobresaliente, incluso al subir levemente el voltaje de nuestra cpu hasta los 1.343v llevándolo casi hasta los 3.9GHz se mantiene completamente firme y estables las temperaturas del Quad Core. Las temperaturas son muy bajas sobre todo destacando el pequeño tamaño del cooler. El nivel sonoro es extremadamente bajo, siendo inaudible si nos movemos por entorno de Windows, no esperábamos menos de este NF-B9.
Resultado del análisis: "Nos hemos quedado sorprendidos del excelente rendimiento alcanzado por este pequeño disipador de cpu de Noctua, muy superior a coolers de mayor envergadura. El fabricante austriaco ha lanzado este NH-U9B al mercado para cubrir el sector de equipos HTPC o chasis pequeños, y ya decimos desde ahora que es si no el mejor, uno de los mejores disipadores del mercado para este sector."

NH-U9B Opinión

Le NH-U9B affiche des performances tout à fait correctes, et qui deviennent même excellentes quand on se rappelle que nous avons affaire non pas à un grand ventirad tour de plus de 15cm de haut, mais d'un modèle d'à peine plus de 12cm ! Il se permet de faire à peu près jeu égal par exemple avec son ainé le NH-U12F, pourtant plus de 3cm plus haut. Son ventilateur est audible en 12V mais reste tout de même tout à fait acceptable, d'autant qu'il bénéficie de cette exceptionnelle qualité de fabrication Noctua qui fait que son bruit est assez agréable, chose que le sonomètre ne peut mettre en évidence. Ses 53dBA sont plus agréables à l'oreille que la plupart des ventirads affichant la même mesure acoustique.

NH-U9B Opinión

Les performances sont vraiment excellentes puique le Noctua NH-U9B se range au côté de ventirads avec ventilateurs de 120mm en étant un peu moins performant que le très bon Hyper 212 de Cooler Master. Il se paie le luxe de dépasser des mastodontes en 120mm comme l'Enzotech Ultra-X (mais à ventilateur horizontal). [...] Les NF-B9 sont vraiment très silencieux, on n'entend rien dans un environnement sonore normal.
Resultado del análisis: "Noctua ne déroge décidément pas à sa réputation en proposant ce petit ventirad évolué. Petit mais très performant. Equippé des tous derniers produits Noctua (ventilateur NF-B9 à pâles crantées et pâte thermique NH-1), il est un excellent choix pour les personnes en quête de performances, silence et petite taille."

Dank des 4 Dual-Heatpipes-Systems und dem effektiven NF-B9 Premium-Lüfter (Vortex-Control Notches, SCD-Antriebssystem und SSO-Bearing) erzielt der neue Noctua Kühler eine mehr als beachtliche Kühlleistung. Selbst die Konkurrenzprodukte mit größerer Kühlfläche und üppigem 120 mm Lüfter können nur bedingt mit unserem Testmuster mithalten. [...] Selbst bei höchster Umdrehungszahl konnten wir den NF-B9 Premium-Lüfter nicht wahrnehmen. Aus diesem Grund können selbst Silent-User bedenkenlos zum Noctua NH-U9B greifen.

Unser Test konnte beweisen, dass nicht unbedingt die Größe Rückschlüsse auf die Kühlleisung geben muss. Natürlich konnte er nicht mit dem deutlich größeren Kühlkörper aus eigenem Hause mithalten, aber andere Konkurrenzprodukte sicherlich schlagen. Außerdem überzeugen uns die Ausstattung, u.a. auch die Wärmeleitpaste, die für sehr viele Anwendungen reicht, das tolle Montagesystem, das leider nur per Backplate funktioniert, die gute Kühlleistung und eine lange Garantiezeit.
Resultado del análisis: "Dafür bietet Noctua [...] ein einmaliges Produkt, nämlich einen leistungsfähigen, recht leisen, kleinen Towerkühler der Edelklasse, der auch gewiss durch sein Aussehen positiv auffällt." (Gordian Hoffmann, Tech-Review.de)

Is the cooler compatible with socket AM2+ and AM3?

Yes. As AM2, AM2+ and AM3 are mechanically identical, the cooler is compatible with all three sockets.

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.

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.

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.

Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?

You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.

PWM PWM

¿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.

Si quieres instalar 2 ventiladores, coloca uno soplando aire y otro absorbiendo.

¿En qué lado del disipador debe instalarse el ventilador?

Por favor instala el ventilador del modo que el aire caliente pueda evacuarse lo más fácilmente posible mediante el ventilador trasero (Opción de flujo de aire 1) o mediante la fuente de alimentación (Opción de flujo 2).

¿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?

Which mainboards are compatible with the NH-U9B?

Please consult our mainboard compatibility list for information about compatible mainboards.

Can I use Noctua fans on my fan controller?

Our fans are compatible with the vast majority of fan controllers on the market. However, there is a compatibility issue with a few models such as the Zalman ZM-MFC2 and Bitfenix Recon, which apply Pulse Width Modulation (PWM) on the 12V line and use an unfavourable PWM carrier frequency. This can create an oscillation when used with certain fans, which will result in the fan speeding up and down. We therefore recommend not using the Zalman ZM-MFC2 or Bitfenix Recon with our fans.

I can’t spread the thermal compound by turning the cooler as described in the manual!

Due to the new LGA mounting bars with screw threads that facilitate the installation process, there's little room to turn the cooler as described in step 4 of the supplied manual. There's nothing to worry about though, as you can still turn the cooler by a few millimetres in order to help the thermal compound spread. We've also made the compound slightly less viscous so that the contact pressure of mounting system is wholly sufficient to spread it.

How can I connect 2 fans?

When using 2 fans, please connect one of the fans to the CPU-Fan header and the second fan to one of the Case-Fan headers of your mainboard. Alternatively, you can also use a 3-pin Y-cable in order to run both fans via the CPU-Fan header. Such cables are available in specialised retail stores.

The fan doesn’t start with the Ultra-Low-Noise Adaptor (ULNA)!

Unfortunately, many Gigabyte mainboards use a special control circuit that can lead to start-up problems in conjunction with the Ultra-Low-Noise Adaptor (ULNA). This control circuit remains active even when automatic fan control is disabled in the BIOS. In these cases, please use the fan without the ULNA or connect it directly to the power supply (or an external fan controller) in order to ensure reliable operation with the ULNA.

My fan doesn’t spin when I start up the PC - is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.

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.
