NH-U12F Review

Kao što smo i očekivali, do značajnijih razlika između coolera (ako izuzmemo Intelov) došlo je tek nakon overclockinga popularnog Q6600 G0 procesor na 3.6GHz pa je stock HSF tu otpao iz igre, dok je Noctua NH-U12F postigao sasvim solidne rezultate.
Test verdict: "Noctua je bez ikakve sumnje ponudila jedan od najboljih coolera koji za hlađenje koji koriste zrak. Osim što je cooler uspio da temperaturu testnog četverojezgrenog procesora zadrži u prihvatljivim granicama, nivo buke je također bio u prihvatljivim granicama, čak i za entuzijaste koji su obično spremni "žrtvovati tišinu" za koji MHz više. U recenziji smo već spomenuli da je na NH-U12F moguće dodati i dodatni ventilator te ostvariti tzv. push-pull kombinaciju u kojoj jedan ventilator puše prema hladnjaku, dok drugi odvlači topli zrak, što u praksi znači još bolje performanse prilikom hlađenja."

NH-U12F Review

Tu wyraźnym liderem okazuje się Noctua NH-U12F, która oferuje świetną wydajność przy naprawdę niskim poziomie hałasu. Przy wentylatorze pracującym z prędkością 700RPM okazuje się ona praktycznie bezgłośna. Drugim z wyróżniających się produktów w tej klasyfikacji jest radiator SilverStone a, który współpracował podczas testów z wentylatorem Noctua S12-1200, identycznym jak w przypadku coolera NH-U12F - hałas towarzyszący pracy Nitrogona NT-06 i Noctuy NH-U12F w tym przypadku jest więc identyczny.
Test verdict: "Najwydajniejszym chłodzeniem dzisiejszego porównania została Noctua NH-U12F, która może się poszczycić również bardzo cichą pracą i łatwym montażem a bogate wyposażenie dodatkowo zwiększa jego atrakcyjność." (Marcin Wilczak, FrazPC.pl)

NH-U12F Review

Im Praxistest zeigt sich der NH-U12F zu Scythes Mugen trotz etwas kleineren Maßen ebenbürtig und bietet neben der Option, einen zweiten 120mm Lüfter zu montieren, noch Reserven für absolut geräuschlosen Betrieb. Da die Ausstattung bei Noctua besser ist und die zusätzliche Halteklammern, ausführliches Handbuch in Farbe, Anti-Vibrationsstreifen und ein mitgelieferter Widerstand, der die Lüfterdrehzahl unabhängig von Software/Lüftersteuerung reduziert, geben wir dem NH-U12F trotz höheren Preises den Vorzug und somit eine uneingeschränkte Empfehlung und damit auch einen Award.
Test verdict: "Dass der NH-U12F noch immer nicht zum alten Eisen gehört, hat er in unserem Test erneut bewiesen. Da 50 € in Anbetracht der Kühlleistung und des Lieferumfangs durchaus fair sind prämieren wir ihn mit dem Value Award." (Thomas Lint, o.v.e.r.clockers.at)

NH-U12F Review

As you can see the Noctua NH-U12F outperformed the other two coolers. At idle the temperature of the processor rose only 1.6°C above the room temperature with the NH-U12F. During load the processor got 10°C less hot with the NH-U12F than with the stock Intel HSF. Besides cooling much better, the NH-U12F was also a lot more silent than both other coolers. [...] Much to my surprise the Ultra Low Noise Adapter barely increased the temperatures. The processor only got 1° hotter with the U.L.N.A. and that's almost negligible if you take the higher room temperature into account. It seems the NH-U12F needs very little airflow to keep the temperatures low. The temperatures without the fan are also still OK. In fact, when you compare the results from this chart with the first chart in which I compared this cooler to the standard Intel heatsink you can see that the NH-U12F without active cooling gets 2°C less hot than the actively cooled Intel heatsink!
Test verdict: "I'm very impressed with the Noctua NH-U12F. The cooler is really big and heavy but it's build quality is excellent and it keeps the processor very cool. Additionally, the noise levels of the Noctua NH-U12F fan are exceptionally low and the package also includes anti-vibration pads and an Ultra Low Noise Adapter to further decrease the noise levels."

NH-U12F Review

For standard clock rates, this cooler hangs with best and is probably the quietest CPU fan this test bench has ever heard. When the U.N.L.A. is attached, the fan produces almost no noise above the base line of the system. Even though it had half as much airflow, the temperatures remained the same for the stock speeds. This is a huge indication of how much capacity this cooler has. In regards to the chipset cooler, it is definitely doing its job. The motherboard temperatures did not rise above +1C from room temperature the entire time.
Test verdict: "When weighing the performance versus the noise production, the NH-U12F and NC-U6 really shine. The fan technology is amazing, the mounting systems are simple, and the cooler has extreme flexibility between audio contentment and all out performance. Hence, both the NH-U12F and the NC-U6 from Noctua earn lots of admiration from this crew." (Chris Hunter, FastSilicon.com)

NH-U12F Review

Sowohl der Kühler von Noctua als auch von Scythe unterbieten sogar die 55-Grad- Grenze (Nocta 51,3, Scythe 53) und arbeiten somit fast 15 Grad kühler als mit dem Intel Pentium 4 550.
Test verdict: "Die getesteten CPU-Kühler unterscheiden sich vom Funktionsprinzip kaum voneinander, denn alle besitzen eine Heatpipe, die die Hitze des Prozessors an die großflächigen Kühllamellen abgibt. Besonders gut gelöst hat dies der Hersteller Noctua. Neben der zwar etwas umständlichen Schraubbefestigung, die dafür aber bombenfest sitzt, ist auch die Lautstärke des verbauten 120-Millimeter-Lüfters (17 dB/A) positiv. Dieser ist kaum zu hören und kühlt unseren 'Hitzkopf' auf sehr gute 66,9 Grad." (Fabian Schusdziara, PC Praxis)

NH-U12F Review

Very impressive, the Noctua NH-U12F can take the lead of all the heatsinks tested here. Especially when heat load is not extremely high it gains quite a nice margin compared to the other heatsinks.
Test verdict: "Noctua's NH-U12F is a great cooler that can compete with products from much bigger well-known companies. Noctua put excellent engineering into the product, for example when you look at the installation process you can see many little details that make installation easier or safer. The manual's layout is one of the best I have ever seen. The Noctua NH-U12F will fit all common sockets on the market today, all required installation clips are included, so even if you change sockets any time soon you can continue using your cooler."

NH-U12F Review

Po ~30 minutowym wygrzewaniu procesora wyniki ciągle na bardzo dobrym poziomie. Freezer 64 Pro dorównuje co prawda Noctui, pamiętajmy jednak, że jest to zupełnie inna klasa produktu. O wiele głośniejszy – ponad 2200RPM i gorszy jakościowo. Wychładzanie – jeden z najważniejszych parametrów. Bardzo istotne jest z jaką wydajnością radiator potrafi rozproszyć nagromadzoną energię cieplną i schłodzić rdzeń/rdzenie CPU. Także i tu Noctua nie zawodzi. Przez około ~1 minutę, zarówno w trybie standardowym jak i U.L.N.A, NH-U12F jest w stanie zmniejszyć temperaturę o jedenaście stopni. I wszystko to w otoczce głuchej ciszy ;).
Test verdict: "W przypadku NH-U12F do czynienia mamy nie tylko z bardzo dobrą wydajnością, ale także z minimalnym wręcz poziomem generowanego hałasu. Z pewnością produkt ten zadowoli wszystkich nadwrażliwych na szmery dochodzące z wnętrza komputera. Także dla tych, którym słoń nadepnął na ucho mogę bez wahania polecić ten model, dzięki bardzo dobrym parametrom pracy oraz bogatemu wyposażeniu." (Jerzy Wasiela, IN4.pl)

NH-U12F Review

In the end the Noctua NH-U12F is a carefully balanced system of heatpipe tower and fan, which performs the designed task of cooling with silence extremely well. It is also a decent performance cooler, reaching overclock levels near the best tested.
Test verdict: "Subjectively, we could hear no noise at all from the mounted Noctua cooler. For those whose first consideration is ultra-low system noise, the Noctua should certainly be on the short list of heatpipe towers worth considering." (Wesley Fink, Anandtech.com)

Which Noctua fan or CPU cooler should I buy? How to choose the right model?

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).

NH-U Airflow

How much space between mainboard and power supply is required when the NH-U12 is installed upright?

When installed upright (see picture below), the NH-U12 may jut out over the upper edge of the mainboard. In this case, the gap required between the upper edge of the mainboard and the power supply in the case is (depending on the position of the CPU socket on the mainboard) up to 25mm. Measured from the upper mounting holes of the CPU socket, the required distance to the power supply unit is 35mm.

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:

Which mainboards are compatible with the NH-U12F?

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.

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 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.

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.
