NH-U12S 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-U12S TR4-SP3 Review

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!
Test verdict: "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)

NH-U12S 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-U12S 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)

NH-U12S TR4-SP3 Review

Wie man anhand der Messungen klar erkennen kann ist Fläche Trumpf und dementsprechend reihen sich die Kühler auch ein. Während bei unserer getesteten Mindestdrehzahl von 600 Umdrehungen alle Kühler in das Limit laufen, sehen die Werte ab 900 Umdrehungen zumindest schon einmal für den Noctua NH-U14S sehr gut aus. Ab 1200 Umdrehungen kommt auch der NH-U12S in Fahrt und kühlt den Prozessor adäquat ohne in das Limit zu laufen. Der Noctua NH-U9 konnte bei unserem Testsetup erst auf maximaler Drehzahl den Threadripper auf Temperatur halten.
Test verdict: "Der Noctua NH-U12S TR4-SP3 konnte aufgrund seiner größeren Kühlfläche auch den leicht übertakteten Threadripper auf 3750Mhz adäquat kühlen. Im Standardbetrieb in Kombination mit seinem Lüfter bleibt der U12S auch etwas leiser als sein kleiner Bruder. Grund genug den U12-S mit unserem Gold Award auszustatten."

NH-U12S TR4-SP3 Review

The results from this benchmark were rather shocking as the Thermaltake Floe Triple Riing RGB 360 TT Premium Edition ($199.99 shipped) AIO CPU liquid cooler didn’t blow the Noctua coolers out of the water. The Thermaltake Floe Triple Riing RGB 360 had the lowest idle temperature by 1C, but the load temps were nearly 2C higher than the Noctua NH-U14S. These Noctua air coolers do a pretty good job!
Test verdict: "It is shocking how well these three high-end heatsinks from Noctua handle AMD’s TR4 and SP3 sockets for their latest Ryzen Threadripper (X399) and EPYC platforms." (Nathan Kirsch, LegitReviews.com)

NH-U12S TR4-SP3 Review

Mit dem NH-U12S TR4-SP3 hat Noctua sein Sortiment um einen schlanken aber dennoch leistungsstarken Tower-Kühler erweitert. Auch wenn der Kühler auf einem schon länger erhältlichen Kühler besteht, hat es Noctua durch die Veränderungen an der Bodenplatte geschafft, dass der Kühler trotz der schlanken Abmessungen mit einer guten Kühlleistung punkten kann, mittels welcher auch eine sehr potente CPU auf angenehmen Temperaturen gehalten wird. Der seitens Noctua eingesetzte Lüfter arbeitet auch bei maximaler Drehzahl mit einer noch recht angenehmen Geräuschkulisse. Die Verarbeitung ist, wie man es in der Zwischenzeit von Noctua gewohnt ist, auf einem sehr hohen Niveau. Durch die geringe Bautiefe wird eine sehr hohe Kompatibilität zu Speichern mit sehr hohen Kühlkörpern garantiert. Durch die verschiedenen Bohrungen am Montagesystem kann zudem auch die Kompatibilität im Bereich des oberen PCIe-Slots gesteigert werden.
Test verdict: "Mit einem Blick auf das Kühlergebnis ist zu erkennen, dass der NH-U12S TR4-SP3 mit einer guten Kühlleistung punkten kann, welche nur knapp hinter der Kühlleistung einer 360 mm großen AiO-Wasserkühlung liegt, welche zum erreichen der Kühlleistung mit gleich drei 120-mm-Lüftern betrieben wird. Nicht nur die gebotene Kühlleistung liegt auf einem guten Level, sondern auch was die Lautstärke angeht, braucht sich der Kühler nicht zu verstecken." (Patrick Seus, mod-your-case.de)

How big is the NH-U12S 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:

U12S

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 fan off the heatsink in order to reduce the weight below 700g. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the fan installed.

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.
