NH-U9 TR4-SP3 Review

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.
Test verdict: "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-U9 TR4-SP3 Review

Кулер обладает действительно высокой эффективностью для своих размеров и, при этом, остаётся достаточно тихим. Несомненным плюсом является высокая совместимость как в плане верхнего PCI-Express слота, так и с ближними к процессору слотами для оперативной памяти. Установка NH-U9 TR4-SP3 на материнскую плату сведена к двум максимально простым действиям – нанести термоинтерфейс и закрутить четыре винта ключом из комплекта поставки. Единственный вопрос, который вы можете задать – связан со стоимостью. Но данный кулер окупает каждую потраченную за него копейку!
Test verdict: "Планируете собрать систему на основе AMD Ryzen Threadripper и хотите тихое, эффективное и компактное охлаждение? Тогда Noctua NH-U9 TR4-SP3 отлично подойдёт на эту роль!" Владимир Солонин, GreenTechReviews.ru)

NH-U9 TR4-SP3 Review

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.
Test verdict: "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-U9 TR4-SP3 Review

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.
Test verdict: "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-U9 TR4-SP3 Review

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.
Test verdict: "Performanse novih Noctuinih hladnjaka za TR4-SP3 platformu u skladu su s našim očekivanjima." (Denis Arunovic, BUG)

NH-U9 TR4-SP3 Review

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.
Test verdict: "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."

NH-U9 TR4-SP3 Review

El Noctua NH-U9 TR4-SP3 se trata de un estupendo disipador para refrigerar a los nuevos procesadores AMD Threadripper 1950X y 1920X de 16 y 12 núcleos respectivamente en velocidades de stock. Consta de una única torre, junto a dos ventiladores de 92 mm de una calidad brutal y una superficie que cubre por completo el IHS del procesador. En nuestras pruebas hemos podido comprobar que en stock tenemos un resultado idéntico respecto a su hermano mayor Noctua NH-U14 TR4-SP3. La cosa cambia cuando hacemos overclock: 4050 MHz y 1.35v, que las temperaturas suben muchísimo: 83 ºC a máxima potencia y 46 ºC en reposo.
Test verdict: "Creemos que el Noctua NH-U9 TR4-SP3 se trata de una buena opción si queremos mantener el procesador en valores de stock o nuestra caja no permite instalar a uno de sus hermanos mayores: Nh-U12 o NH-U14." (Miguel Ángel Navas Carrera, ProfesionalReview.com)

NH-U9 TR4-SP3 Review

Noctua NH-U9 TR4-SP3: in ambiente server, il Noctua NH-U9 sembra essere la scelta giusta, vista la compatibilità con sistemi rack 4U per via delle ridotte dimensioni. Nonostante, però, la taglia ridotta rispetto ai “fratelli maggiori”, le temperature raggiunte sono, in rapporto appunto ad esse, di ottimo livello. Noctua NH-U12S TR4-SP3: il “fratello di mezzo” è un piccolo campione, che allo stesso prezzo del modello di fascia inferiore riesce ad essere molto vicino in prestazioni al modello con ventola di dimensioni superiori, più heatpipes e alette più larghe. Nonostante ciò, le dimensioni inferiori permettono di avere una completa compatibilità con qualsiasi configurazione, non interferendo né con slot di memoria né con slot PCIe. Noctua NH-U14S TR4-SP3: il modello più performante, ingombrante e silenzioso dei tre, con una ventola da 140 mm capace di spostare tanta aria con una pressione statica elevata, il tutto tenendo a bada un processore “focoso” come il 1950X, anche in alcune verifiche in overclock dove la CPU ha raggiunto l’impressionante assorbimento di ben 440 W.
Test verdict: "Anche stavolta Noctua pensa ad AMD, con una linea di dissipatori dedicata ai processori Threadripper ed EPYC: la serie TR4-SP3." (Ciro Sdino, ReHWolution.it)

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

Please refer to our socket compatibility chart.

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).

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.

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.

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.

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

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 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.
