NH-U9B test

Tai puikus aušintuvas tiems, kurie turi poreikį spartinti procesorių, tačiau neturi didelio pakankamai didelio korpuso, kuriame tilptų didelis aušintuvas su radiatoriumi. Pagal savo dydį NH-U9B SE2 parodė labai gerus aušinimo rezultatus, o turbinant procesorių sugebėjo palaikyti stabiliai veikiančią sistemą.
Verdict du test: "Manau tai yra vienas iš geriausių kompaktinės klasės aušintuvų rinkoje." (Marius Kavaliauskas, Techpill.lt)

NH-U9B test

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.
Verdict du test: "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)

NH-U9B test

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.
Verdict du test: "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 test

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.
Verdict du test: "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 test

Štai ir testų rezultatai. Idle rėžimu NH-U9B aušintuvas buvo lygus su Scythe Katana 3 aušintuvui, bet pridėjus antrą NF-B9 aušintuvą NH-U9B aušintuvas tapo nepralenkiamas. Load rezultatų kovoje vyravo tokia pati situacija.
Verdict du test: "Noctua NH-U9B aušintuvas yra puikus pasirinkimas HTPC ar nedidelį korpusą turinčių kompiuterių savininkams. Dėka tylaus darbo ir puikių aušinimo rezultatų NH-U9B tampa pilnaverčiu šios kategorijos lyderių mūsų puslapyje. Bet jeigu žadate spartinti procesorių jums nepamaišytu įsigyti papildomą NF-B9 aušintuvą ir jį naudoti kartu su NH-U9B aušintuvu. To dėka galėsite šį procesoriaus aušintuvą išnaudoti maksimaliai."

NH-U9B test

Apkrauto procesoriaus temperatūros rodikliai yra tai, pagal ką galime nustatyti tikrąjį aušintuvų efektyvumą. Lyderiai čia nesikeičia – NH-U9B veikiantis su dviem NF-B9 ventiliatoriais ir Nepartak rodantis vienu laipsniu prastesnius rezultatus. Dar vienu-dviem laipsniais nuo to paties Nepartak atsilieka standartinis Noctua aušintuvo modelis. [...] Pabaigoje – triukšmo lygio matavimo rezultatai, kurie parodo, ar daug vartotojas aukoja vardan gero aušinimo efektyvumo. Tiesą pasakius, rezultatai nė kiek nestebina – žinodami NH-U9B ventiliatorių nedidelę spartą ir negalėjome tikėtis didelio triukšmo lygio.
Verdict du test: "Noctua NH-U9B iš karto leidžia pajusti nuostabią pagaminimo kokybę ir kompanijos norą išlikti viena solidžiausių rinkoje. Tai leidžia padaryti ne tik išskirtinai turtingas komplektas, būdingas ir kitiems Noctua gaminiams, tačiau ir puiki pagaminimo kokybė bei labai geras aušinimo efektyvumas, nepaisant itin mažos ventiliatorių spartos, dėl ko aušintuvas yra itin tylus. Dar vienas NF-B9 ventiliatorius pastebimai pagerina našumą, tačiau prideda šiek tiek triukšmo." (Darius Buinauskas, Technews.lt)

NH-U9B test

Bei unserem Testmuster war während des Betriebs mit 12 Volt - ca. 1650 U/min (17,6 dB(A) nur ein Rauschen bei einer Entfernung von ca. 50 cm wahrnehmbar und war zu keinem Zeitpunkt störend. Die Förderleistung von 64,3 m³/h (Herstellerangabe) ist bei der gebotenen Geräuschentwicklung hervorragend. Mit dem beiligenden Low-Noise-Adapter L.N.A.(Schwarz - 13,1 dB(A) - ca. 1300 U/min) war der Lüfter praktisch schon nicht mehr hörbar. Die Förderleistung von 52,6 m³/h (Herstellerangabe) ist immer noch gut.
Verdict du test: "Auch der NF-B9 aus dem Hause Noctua konnte überzeugen. Wie der große Bruder NF-P12 ist auch der NF-B9 in Sachen Lieferumfang, Leistung und Geräuschentwicklung hervorragend. Im Grunde ist der Lüfter für jedes System, das Platz für einen 92 mm Lüfter bietet, bestens geeignet." (Mathias Kossin, Overclocking4you.de)

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

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.

Le poids élevé représente-t-il un danger pour le processeur central ou le socle ?

Non. Les refroidisseurs Noctua disposent d'un système de montage SecuFirm™ très fiable. Grâce au vissage sûr avec une plaque de montage au dos de la carte mère, le dépassement des recommandations de poids données par Intel et AMD, qui est normal pour les refroidisseurs high end, ne présente pas de danger et est sans inconvénients.

Puis-je monter aussi des ventilateurs d'une hauteur supérieure à 25 mm ?

Oui. Les agrafes de montage des refroidisseurs NH-U s'engrènent dans les trous de passage des vis à la face inférieure du cadre du ventilateur et fonctionnent pour cette raison pour les ventilateurs de toutes les hauteurs. Des problèmes de montage ne peuvent être causés que par d'autres éléments dans le boîtier en cas d'utilisation de ventilateurs présentant des formes de cadre spéciales, pour lesquels les agrafes ne peuvent pas s'engrener dans les trous de passage des vis à la face inférieure.

Veuillez monter le ventilateur de manière à ce qu'il souffle vers le refroidisseur.

NH-U Airflow

Si vous voulez utiliser deux ventilateurs, veuillez monter l'un de manière à ce qu'il aspire et l'autre de manière à ce qu'il souffle.

De quel côté du refroidisseur le ventilateur doit-il être monté ?

Veuillez monter le ventilateur de manière à ce que l'air chaud puisse être évacué vers l'extérieur le mieux soit à travers le ventilateur de boîtier arrière (option de courant d'air 1) ou à travers le bloc secteur (option de courant d'air 2).

NH-U Airflow

Est il possible de refroidir mon CPU sans ventilateur (passif)?

Radiateurs Noctua n’sont pas conçus à l’origine pour des opérations passives quoique la performance du refroidisseur soit suffisante dans beaucoup de cas. Malheureusement, il nous est impossible de vous indiquer quelles sont les CPU qui peuvent ou qui ne peuvent pas être refroidir sans ventilateur, car il dépend de nombreux facteurs comme la température, la ventilation ou orientation du socket. Généralement, nous recommandons, dans un premier temps, utiliser le ventilateur et de diminuer progressivement RPM en surveillant constamment la température.

How to install the fan using the supplied steel clips?

First hook the clip into the notch of the heatsink:

Quelles cartes mères sont compatibles avec le NH-U9B?

Pour obtenir de l'information sur la compatibilité des cartes mères, consultez notre liste de compatibilité s'il vous plait.

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.

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.

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.

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

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.

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.

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.

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.

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.

The following models include a mounting-kit for socket LGA2011/2066 and are thus compatible out of the box:

NH-C14S
NH-D14 SE2011

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 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 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.

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

The following models include a mounting-kit for socket AM4 and are thus compatible out of the box:
