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.

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.

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.

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.

NH-U9B Opinión
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.

Is the cooler compatible with socket AM2+ and AM3?
My unlocked Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?
- the TDP limits are extended or disabled in the motherboards' BIOS.
- the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
- 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?
Which Noctua CPU coolers are compatible with Intel LGA2066?

How should I clean my Noctua cooler?
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?
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?
I have difficulties installing the cooler, can you help?
How much torque should be applied when tightening the screws of a Noctua CPU cooler?
Screw type | Max. torque |
---|---|
NM-SSC1 screws for fixing the fastening brackets to the base of the heatsink | 0.5 Nm |
NM-ITS1 thumb screws for fixing Intel mounting bars | 0.5 Nm |
NM-ALS1 screws for fixing AMD mounting bars | 0.6 Nm |
Spring-loaded screws for fixing the heatsink to the mounting bars | 0.6 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.
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.
