NH-U14S TR4-SP3 test

You probably will already have noticed it, but the U12S and U14S managed to cool better than the Kraken X40 LCS cooler, especially the U14S crunches down the cooling numbers. That's impressive, but also wasn't a very likely thing to happen. Here's my thought on that, it's the full cover heat block on the Noctua coolers that draw every Watt of heat they can deal with until they run out of capacity. Even tweaked with 16 cores at 100% stress / 1.38V the U14S managed to stay four degrees cooler compared to that Kraken X40 LCS unit, which is a lot in the cooling arena. Now of course, once you go pro with liquid cooling and bigger radiators, the dynamics will shift. But none-the-less this was very impressive to see.
Verdict du test: "So there you have it, overall we feel the Noctua U12S and NH-U14S coolers are very nice, the looks are a matter of taste, the performance winner, however, is the NH-U14S TR4/SP3." (Hilbert Hagedoorn, Guru3D.com)

NH-U14S TR4-SP3 test

Старшая из трёх доступных моделей, Noctua NH-U14S TR4-SP3, продемонстрировала впечатляющую эффективность, оставив пользователю задел для разгона даже флагмана – Threadripper 1950X. Кроме того, данный кулер обладает очень низким уровнем шума даже при использовании пары вентиляторов (NF-A15 PWM), но за это есть своя цена и выражается она не только в деньгах. На некоторых материнских платах один PCI-Express слот может быть полностью заблокирован, что требует от вас внимания при выборе материнской платы. Что касается установки – никаких проблем в процессе сборки системы больше быть не может. С оперативной памятью всё прекрасно – модули можно выбирать с радиаторами любой высоты.
Verdict du test: "На данный момент Noctua NH-U14S TR4-SP3 является самым эффективным решением для Threadripper (или Epyc) в сегменте воздушного охлаждения!" Владимир Солонин, GreenTechReviews.ru)

NH-U14S TR4-SP3 test

For people wanting to keep it simple, air cooling is about as simple as it gets. All three coolers from Noctua are very capable and allow flexibility for different case constraints, noise or overclocking. Some of the AIO water coolers appear to have smaller water blocks consistent with other sockets, perhaps more generic, which limits the heat transfer of the dual die Threadripper CPU. These Noctua coolers all have the larger purpose-built CPU plate designed specifically for AMD’s Threadripper CPU series to maximise the heat transfer CPU to the heat pipes and fins. These are not coolers simply adapted to fit a 180W high-end CPU but rather new coolers based on tested production designs to get optimal heat conversion.
Verdict du test: "After testing these fans my pick would be the U14S installed with a 3mm offset, and for a personal build, I would choose this over a water-cooler unless I planned to do some serious overclocking." (Phil Carroll, PCTechReviews.com.au)

NH-U14S TR4-SP3 test

First off is the most important result, which is that while the tiny NH-U9 managed to tame the mighty Threadripper 1950X, it couldn't do this when I used the low noise adaptor as the CPU hit 87°C in Ryzen Master and began to throttle back. There's no harm being done when it does this, but equally you'll be losing performance as well as running your CPU at high temperatures. Using the fans at full speed saw it just about manage to keep things in check, which is amazing for such a tiny cooler. The NH-U12S fared much better, with a temperature of 76°C after 10 minutes of full load, rising to 79°C using the low noise adaptor - even this was noticeably cooler than the best result that the tiny NH-U9 managed. However, the star of the show is the NH-U14S, which managed to cool the Threadripper 1950X all the way down to 70°C and 74°C using the low noise adaptor.
Verdict du test: "It's rare that there's such a clear choice in tests like this, but the fact that all the coolers are so close in price means that the NH-U14S is the only cooler to consider here if your case has the space for it." (Antony Leather, Forbes.com)

NH-U14S TR4-SP3 test

Na standardnom taktu najveći je hladnjak minimalno slabiji od Thermaltekovog skupog vodenog hlađenja, a maksimalna je temperatura procesora s manjim modelima četiri, odnosno pet, stupnjeva viša. S prelaskom na overklokiranje temperature osjetno skaču, i tu razlika između Noctuinog najvećeg hladnjaka i Thermaltakeovog sustava raste na tri stupnja. NH-U12 S topliji je za četiri dodatna stupnja, no, nažalost, više nije u stanju držati procesor na definiranom radnom taktu. Zbog povremenog pregrijavanja dolazi do termalnog throttlinga, u kojem procesor automatski smanjuje svoj množitelj s 39 na 5,5 kako bi se zaštitio. NH-U9 neznatno je lošiji u pogledu maksimalne temperature (88 vs. 87 stupnjeva) pa i tu dolazi do automatskog usporavanja procesora. Što se tiče buke, Thermaltakeov sustav bio je najtiši, potom Noctuini hladnjaci od najvećeg prema najmanjem. Ipak, sve je to buka u granicama normale, odnosno ispod razine od 50 dB(A). U praksi će Noctuini hladnjaci biti i tiši zbog korištenja automatskih profila za reguliranje brzine ventilatora pa će se do maksimalne razine buke dolaziti samo prilikom intenzivnog i konstantnog opterećenja.
Verdict du test: "Performanse novih Noctuinih hladnjaka za TR4-SP3 platformu u skladu su s našim očekivanjima." (Denis Arunovic, BUG)

NH-U14S TR4-SP3 test

Der NH-U14S TR4-SP3 unterscheidet sich nicht nur durch einen größeren 14-cm-Lüfter vom kompakteren 12- cm-Modell, sondern hat auch weiter ausladende Kühllamellen sowie sechs statt fünf Heatpipes. Deshalb bringt er knapp über ein Kilogramm Masse auf die Waage. In den Messwerten spiegelt sich der Größenunterschied wider: Unter Volllast auf allen 16 Kernen und 32 Threads liegt die Kerntemperatur des Ryzen Threadripper 1950X mit 59ˇ°C 9ˇ°C unter der des NH-U12S TR4-SP3. Bei einer Drehzahl von 1400 U/min ist das Lüftergeräusch deutlich wahrnehmbar, aber nicht störend (1,1 Sone). Die Montage klappt auch hier einfach. Aufsetzen, mit dem mitgelieferten Werkzeug festschrauben, Lüfterkabel aufstecken, fertig!
Verdict du test: "Alle drei getesteten Kühler schaffen es, AMDs schnellsten Desktop-Prozessor vor dem Überhitzen zu bewahren. Die meisten Reserven bietet dabei der größte Kühler NH-U14S TR4-SP3 von Noctua. Dabei arbeitet er wie der kleinere NH-U12S TR4-SP3 mit annehmbarer Lautstärke." (Christian Hirsch, c’t)

Что касается самих Noctua NH-U14S TR4-SP3, Noctua NH-U12S TR4-SP3 и Noctua NH-U9 TR4-SP3, то здесь обошлось без неожиданностей — как приятных, так и не приятных. Единственное отличие в данных моделях от ранее выпущенных австрийских кулеров заключается в большом основании и изменённом креплении. При этом мы не можем не отметить, что две старших модели наделены полезной возможностью смещения на процессоре по ширине, чтобы можно было немного отодвинуть радиатор от первого слота PCI Express на материнской плате. Традиционно высокое качество Noctua, повсеместно используемая пайка, долговечные вентиляторы и возможность установки дополнительного вентилятора на радиатор, шестилетняя гарантия, надёжная упаковка, ставшая ещё и компактнее, – вот сильные стороны новых систем охлаждения. Стоимость кулеров, конечно, высокая, но у Noctua по-другому никогда и не было.
Verdict du test: "Ну что же, все кулеры прекрасно справились с поставленной задачей и охладили шестнадцатиядерный процессор при нагрузке, генерируемой Prime95. При этом все три модели расположились на диаграмме в строгой иерархии, когда лидирующие позиции занимает старший NH-U14S, на втором месте – NH-U12S, а замыкает список NH-U9."

Pourquoi le fond du refroidisseur Noctua n'est-il pas brillanté et poli ?

Etant donné que la plupart des enthousiastes d'ordinateurs personnels utilise encore aujourd'hui des pâtes thermiques à forte viscosité, le fond du refroidisseur Noctua a été optimisé pour l'utilisation de ces pâtes. Les fines rainures (micro-grooves) dans la surface du fond du refroidisseur Noctua permettent d'appliquer les pâtes thermiques à forte viscosité de manière homogène en une couche ultramince et sans aucune inclusion d'air n'existe entre le refroidisseur et la processeur central. Le risque d'une application non homogène serait beaucoup plus élevé si la surface était brillantée et polie. Des couches de pâte thermique trop épaisses et des inclusions d'air altérant sensiblement la transmission calorifique, les micro-rainures sont d'une importance décisive pour la performance de refroidissement totale du refroidisseur Noctua en cas d'utilisation des pâtes thermiques courantes à forte viscosité.

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.

The supplied y-cable is missing a wire at one of the two connectors, is it faulty?

No. As mainboards can process only one rpm-signal per fan header, it would cause problems if the cable transmitted rpm-signals of both fans. For this reason, one of the two connectors does not have an rpm wire and only the fan on the other connector will transmit an rpm signal. Automatic speed control of both fans will work independently from the second fan’s rpm signal.

I get a CPU fan error using my Noctua PWM fan, is it faulty?

Noctua PWM fans feature a minimum speed of 300rpm to allow for ultra quiet operation when your CPU is at idle state and doesn’t require higher cooling performance. Some mainboards display error messages such as “CPU fan error” during the booting process when the fan speed is below a certain level. If you get such error messages using your Noctua PWM fan and if such options are available in your BIOS, please either adjust the minimum fan speed monitoring limit to 200rpm or increase the minimum PWM duty cycle. If your BIOS doesn’t offer these options, please disable CPU fan errors. For detailed information on BIOS fan settings, please consult your mainoard’s manual or contact your mainboard manufacturer.

My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.



To resolve the issue, you can:

  1. Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.

  2. Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.

  3. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?

The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:

  1. Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.

  2. Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

    4 pin fan header types

    Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

    Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

    Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.


    If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?

The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control.. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.

Unfortunately there is usually no option to set a lower minimum value that would suit the low minimum speed of Noctua PWM fans.The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

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.

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.

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.

How can I check whether my case is wide/high enough for the cooler?

Most case manufacturers provide specifications for maximum CPU cooler height/clearance. Please refer to these specifications in order to verify that the cooler will fit the case. If no specifications are available, please contact the case manufactuer or measure the distance from the motherboard tray to the side panel (tower cases) or top panel (desktop cases). If this distance is bigger than the height of the cooler + 15mm (mainboard spacers + mainboard + CPU), the height/width of your case should be sufficient.

How big is the NH-U14S and how much clearance does it provide for RAM and chipset coolers?

Please refer to the following drawing for the exact measurements and clearance for RAM and chipset coolers:

U14S

I’ve used all the NT-H1 thermal compound that came with the cooler, can you send me more?

Please kindly note that the NT-H1 thermal compound supplied with our coolers is a consumable item so our manufacturer’s warranty does not include providing additional thermal compound. You can purchase NT-H1 from our resellers.

Can I install a 140mm fan with a square frame (e.g. NF-A14)?

No. Square 140mm fans like the NF-A14 would cause compatibility issues in many configurations and use a hole spacing of 124.5mm. The cooler's fan clips are designed for 105mm hole spacing as used by round 140/150mm and square 120mm fans.

Which sockets are supported or can be supported using upgrade kits?

Please refer to our socket compatibility chart.

Should I take the cooler off before transporting my system?

As it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, for safety reasons, taking the cooler off. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the heatsink installed.

Does the NF-A15 PWM that comes with Noctua coolers run at a different speed (1500rpm) than the retail model (1200rpm)?

Yes, the NF-A15 PWM bundled with our heatsinks is specified to run at 1500rpm (see cooler specifications for details) and the retail model is specified to run at 1200rpm (see fan specifications for details). The 1200rpm retail model is ideal for setting up push/pull configurations in combination with the coolers’ 1500rpm stock fan because the combination of the 1500 and 1200rpm models provides a better balance of performance and noise than the combination of two 1500rpm versions. On dual-tower coolers such as the NH-D15S, we recommend to run the 1500rpm version in the center and the 1200rpm version on the front. On single-tower coolers such as the NH-U14S, we recommend to run the 1500rpm version on the front and the 1200rpm version on the back of the cooler. The NA-YC1 y-cable supplied with the retail fan can be used in order to control both fans via one PWM fan header. In this case, both fans will scale individually according to the PWM duty cycle supplied by the motherboard, e.g. they will run at ~1500/1200 respectively at 100% duty cycle, ~750/600rpm at 50% duty cycle, etc. Both at 100% and lower speeds, the speed difference between the fans reduces resonance phenomena and thus helps to achieve the best balance of performance and noise.

I get a CPU fan error despite the fan is running!

Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

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.
