NH-U9F Opinión

Testing the NH-U9F was fun and easy, its not as combersome as large 120mm based CPU coolers, it was easier to fit that its bigger brother NH-U12F, and space awareness around the processor area is not too much of a concern. Another plus factor is that the heatsink can be installed facing east-to-west (standard) or if space is restricted it can be fitted facing north-to-south. Cooling performance was great, heat transfer from the CPU core into the heatsink was as efficient as its bigger brother NH-U12F, probably due to the fact that the same design principle in the copper base and four heatpipe was used.
Resultado del análisis: "A great cooling performance from a standard sized heatsink, compatible with all new socket fittings. Super silent fans and size are a big positive" (Kwok Yao Chim, CPU3D.com)

NH-U9F Opinión

We can plainly see that the Noctua blows away the Intel stock cooler, and beats the Thermalright SI-128, only the Coolermaster HyperTX has better temps than the Noctua, and they are very close especially at idle. The main difference is that the Noctua is virtually silent, and I didn't even use one of the included adapters, I hooked it straight to the motherboard fan header. The Noctua NH-U9F is the quietest CPU cooler I have ever owned or reviewed, Noctua knows silence and performance should go hand in hand. I can easily trade the silence of the Noctua for the extra one degree of coolness that the HyperTX gives while being louder and bigger.
Resultado del análisis: "[T]he Noctua NH-U9F is an extremely good CPU cooler, with excellent cooling performance and and a very low noise level. The Noctua NH-U9F is something that is made with care, high quality and performance in mind and I can easily recommend it to anyone looking to upgrade there CPU cooling system to something much better and much quieter than the stock cooler."

Der verwendete Lüfter war selbst bei voller Drehzahl und geschlossenem Gehäuse nur mit absoluter Konzentration minimal wahrnehmbar. Bei Verwendung der beiden Adapterkabel zur Drehzahlreduzierung war kein Geräusch des Lüfters mehr hörbar.
Resultado del análisis: "Mit dem NF-U9F hat die Firma Noctua eindrucksvoll bewiesen, dass das Ziel geräuschoptimierte Premium-Komponenten anzubieten keine Floskel ist. Der Noctua ist selbst bei Höchstdrehzahl kaum wahrnehmbar und kühlt dabei recht ordentlich." (Michael Nürnberger, Technic3d.com)

NH-U9F Opinión

Sehr überzeugt hat uns die quasi nicht vorhandene Lautstärke des Kühlers. Leider fehlen uns Meßinstrumente, die empfindlich genug sind, derart niedrige Schallpegel zu erfaßen. So müßen wir uns auf eine Beschreibung des subjektiven Wahrnehmens beschränken. Mit dem "Ultra Low Noise Adaptor" muss man schon mit dem Ohr direkt an den laufenden Lüfter gehen, um ein Geräusch wahrzunehmen. Aber auch selbst ohne Drehzahlbegrenzung wird der Kühler bei geschloßenem Gehäuse unhörbar. Die Angaben von Noctua - 7db(A) bis 11db(A) bei Verwendung der beiden Widerstands-Kabel - sprechen bereits eine Sprache für sich und sollten selbst eingefleischte Passiv-Fanatiker dazu bewegen, ihrer Hardware etwas mehr Kühlung zu gönnen.
Resultado del análisis: "Hier hat Noctua wirklich gute Arbeit geleistet. Dieser Kühler platziert sich auf Anhieb ganz vorne in die Reihen der Silent-Produkte." (Fabian Erdmann, HardwareCrew.com)

NH-U9F Opinión

Von Lautstärke kann man bei diesem Kühler eigentlich nicht sprechen. Ohne den Adapter für mich schon nicht mehr herauszuhören bei geschlossenen Case. Für echte Silent Freaks wahrscheinlich schon. Für User für die extrem Silent ein Muss ist legt Noctua noch 2 Adapter bei, den Low-Noise Adapter (L.N.A.) & Ultra-Low-Noise Adapter (U.L.N.A.). Damit wird auch die letzte Lautstärke eliminiert. Selbst der Passiv Betrieb ist, wie man am Temperatur Test sieht, möglich - somit ist der Kühler 100% geräuschlos.
Resultado del análisis: "Noctua hat mit dem NH-U9F ein wahres Meisterwerk von Kühler abgeliefert." (David Kortmann, HotCases.de)

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

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.

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.

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.

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.

¿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.

Which mainboards are compatible with the NH-U9F?

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.

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.

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.
