NH-U12S TR4-SP3 Review

Coolerele Noctua sunt bine cunoscute in lume, datorita performantelor deosebite dovedite de-a lungul timpului, pe toate platformele desktop. Astăzi, am pe birou variantele NH-U14S TR4-SP3, NH-U12S TR4-SP3, NH-U9 TR4-SP3, care au fost lansate special pentru procesoarele AMD Threadripper. Coolerele sunt iterații ale precedentelor variante, dar au primit 2 numere mai mari la picior si sufixul TR4-SP3.
Test verdict: "Testele au arata o performata excelenta, in special pentru NH-U14S, astfel ca Noctua își menține standardul si oferă utilizatorilor soluții, de răcire, foarte bune." (Daniel Neacsu, Techzone.ro)

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)

NH-U12S TR4-SP3 Review

Con esta review damos fin a nuestro vistazo a los tres primeros disipadores del fabricante austriaco de soluciones de refrigeración, el nuevo Noctua NH-U12S-TR4/SP3 ofrece una solución de gama media dentro de estos disipadores que tienen que enfrentarse a unos procesadores con un TDP de hasta 180W y esto sin overclock, por lo que los consumos con overclock pueden dispararse por encima de los 200W fácilmente y este disipador, según demuestran nuestras pruebas ha sido capaz de mantener la talla en cualquier tipo de tarea en pleno verano. Noctua ha aprovechado inteligentemente el tener que diseñar un bloque mucho más grande para cubrir todo el IHS de AMD Ryzen Threadripper adoptando un diseño de cinco heatpipes dentro de su radiador de estilo torre. El uso de un solo ventilador de 120mm no ha sido insuficiente y el fabricante además ofrece la opción de instalar una segunda unidad para extraer el aire del radiador en el otro lado, aumentando de esta manera de forma notable el rendimiento. Por si fuera poco, el ventilador incluido mantiene una sonoridad muy baja de 22,4 dB a sus máximas revoluciones, que podremos reducir hasta 18 dB máximos en caso de usar el adaptador Low Noise y que será menor gracias a la regulación PWM mientras no necesitemos todo su potencial.
Test verdict: "En conclusión, no podemos más que otorgarle a este disipador nuestro mayor galardón OCKD Platino, ya que en calidad Noctua siempre esta al máximo que podríamos imaginar y que podamos encontrar un disipador de esta calidad por un precio de alrededor de los 78€ es una gran noticia."

NH-U12S TR4-SP3 Review

Voor wat overclockwerk richting de praktische limiet van de meeste Ryzen CPU’s (3,9-4,0 GHz) lijkt de NH-U14S de meest logische, want die is niet alleen nipt wat koeler op stock speeds maar neemt ook een grotere voorsprong wanneer het voltage omhoog gaat; de NH-U9S loopt met een voltage van 1,3-1,35V duidelijk verder op en een behuizing met degelijke airflow lijkt dan wel het uitgangspunt. Ook met het oog op een nog wat warmere Threadripper 1950X met OC lijkt de NH-U14S wel het pad om te volgen; de andere twee kunnen het zeker ook, maar als de verwachting dan is dat het prijsverschil erg beperkt blijkt tussen de NH-U14S en de NH-U12S terwijl we al over minimaal 1200 euro aan CPU en moederbord praten dan lijkt dat mij eigenlijk geen overweging meer. Aan de andere kant zien we ook voldoende potentie dat een NH-U12S en zelfs de NH-U9S op een 1950X geen problemen gaan hebben als je ze niet hard op hun staart gaat trappen, dus wanneer de hoogte in je case beperkt is is het fijn te weten dat er tenminste twee compactere torens zijn die zo’n CPU wel bijbenen. Wellicht zelfs dat er dan alsnog wat OC ruimte in blijkt te zitten, iets wat ik vooraf als onmogelijk had geschat.
Test verdict: "Hoe dan ook, ik ben heel erg positief verrast door alle drie de koelers op deze toch hele dikke CPU. Threadripper bouwers hoeven zich volgens mij geen zorgen te maken met oplossingen als dit tot hun beschikking." (Stephan Overbeeke, TechTesters)

NH-U12S TR4-SP3 Review

Za istih tih 70 € se može kupiti puno bolji NH-U12S TR4-SP3 koji je dobar i po pitanju performansi i po pitanju buke. Najtiši je na testu, a čak je pod kakvom takvom kontrolom držao i overclockirani 1920X. Za ovaj hladnjak je topla preporuka kupiti još jedan F12 ventilator jer se to osjeti na performansama. Najmoćniji NH-U14S TR4-SP3 je dobar i za overclocking, kada mu također dobro dođe još jedan ventilator. Cijena mu je oko 80 €. Kvaliteta izrade sva tri hladnjaka je kao i uvijek na najvišem nivou, i svakako opravdava cijenu. Dva veća hladnjaka nemaju problema ni s kompatibilnošću, a pozitivno je što se mogu pomicati od PCIe slota prema vrhu ploče.
Test verdict: "Noctua je još jednom iskoristila svoj uspješan recept i stvorila tri hladnjaka za AMD-ove nove TR4 i SP3 sockete." (Krešimir Matanović, PC Ekspert)

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.
