A simple, elegant installation platform and professional-grade cooling ability lands the Noctua NH-U12S TR4-SP3 placement on any performance-oriented Threadripper PC build. Test verdict: "Just like the original NH-U12S, the Threadripper-ready Noctua NH-U12S TR4-SP3 is poised as a long-term, benchmark CPU cooler for AMD enthusiasts." (Garrett Carver, Tom's Hardware) 28.02.2018 // Le Comptoir du Hardware NH-U12S TR4-SP3 Review Inutile de régler votre poste, ceci n'est pas une hallucination. La grosse surprise nous vient d'un système de refroidissement par air de chez Noctua, qui se positionne comme l'un des plus endurant sur notre Threadripper 1920X. Le NH-U14S TR4-SP3 survole le débat en aircooling et enterre quasiment tout le panel de kits AIO. [...] Le candidat à disposer du meilleur ratio performances/bruit est le NH-U14S TR4-SP3 de Noctua, encore lui. Il se fera largement entendre lorsqu'il sera sollicité au maximum de ses capacités, mais reste toutefois dans une tranche raisonnable. Test verdict: "Le NH-U14S TR4-SP3 remporte notre coup de coeur, offrant le meilleur ratio performances/nuisances/prix du panel. Si l'overclocking ne vous intéresse pas, le NH-U12S TR4-SP3 est parfaitement adapté à l'usage." (Thierry Comtesse, Le Comptoir du Hardware) 04.10.2017 // LegitReviews.com 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) 21.08.2017 // ComputerBase.de NH-U12S TR4-SP3 Review Bei dem Temperaturen zeigt sich die All-in-One-Wasserkühlung nur für wenige Minuten überlegen, denn das Wasser zu erhitzen braucht seine Zeit. Nach 30 Minuten Last mit Prime95 steht ein Patt mit dem NH-U14S zu Papier. So lange die AiO braucht um auf Touren zu kommen, so lange braucht sie im Anschluss auch wieder um ruhiger zu werden: Ein Luftkühler hat nach wenigen Sekunden im Leerlauf die Drehzahl bereits wieder abgesenkt, weil die CPU nur noch minimale Abwärme erzeugt, bei der AiO dauert das länger. Test verdict: "Als potentiell erste erhältliche Luftkühler für AMDs neuer Threadripper-Plattform machen Noctua NH-U14S, -U12S und -U9 für Sockel TR4 eine sehr gute Figur. Das Topmodell NH-U14S schlägt bei der Temperatur sogar eine 200 US-Dollar teure AiO-Wasserkühlung von Thermaltake mit großem 360er-Radiator." (Volker Rißka, ComputerBase.de) 18.12.2018 // DDWorld.cz NH-U12S TR4-SP3 Review Jak vidíte, uchladit moderní multijádrové procesory dá docela práci a klasické vzduchové chladiče zde už ukazují své limity. A to RYZEN 2950X není zdaleka nejvýhřevnější procesor na trhu, to Core i9 dokáže topit ještě mnohem více. Takže ano, všechny chladiče včetně malé 92mm NOCTUA U9 jsou běžně použitelné i pro tenhle čip a uchladí ho tiše i v maximální zátěži! Test verdict: "Pokud tedy máte z nějakého důvodu málo místa tam, kam se snažíte X399 a ThreadRipper nacpat a U14S se vám nevejde, jsou U12S a U9 určitě možnosti. Zejména U9 se vejde do klasických racků a vzhledem k rozměrům docela překvapí, že je vůbec schopna tohle uchladit a stále ještě s přijatelnou nízkou hlučností." (Jan Stach, DDWorld.cz) 05.11.2018 // WhatNext.pl NH-U12S TR4-SP3 Review Chłodzenie zapewnia dobre temperatury podczas pracy Threadrippera a także prezentuje dobrą kulturę pracy. Umożliwia ono też OC procesora. Warto też zwrócić uwagę na świetną jakość wykonania. Według mnie spokojnie możecie je kupować – nie będziecie tego żałowali. Test verdict: "Według mnie spokojnie możecie je kupować – nie będziecie tego żałowali." (Michał Andruszkiewicz, WhatNext.pl) 15.06.2018 // FunkyKit.com NH-U12S TR4-SP3 Review The NH-U12S TR4-SP3 cooler is an alternative to the NH-U9 TR4-SP3. If we have more space in the PC case then it can be a bit better option. It’s quiet, performs well and is the top quality product so we don’t have to worry about any compatibility issues or anything else. Test verdict: "Noctua NH-U12S TR4-SP3 is a great cooler for the most demanding processors." (Bartosz Waluk, FunkyKit.com) 05.12.2017 // Guru3D.com NH-U12S 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) 06.10.2017 // Hardwaremax.net 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."

Which Noctua coolers are compatible with Ryzen Threadripper 2? Even with a high-end cooler, the performance is not what I would expect, what can I do? Should I take the cooler off before transporting my system? After some time of prolonged full load, the CPU clock starts to drop off to very low values intermittently, is the cooler insufficient? This behavior is usually due to overheating of the voltage regulation module (VRM), which provides the CPU with power. To stay within a defined temperature threshold (defined by the component and motherboard vendor) and to cool down the VRM, the clock speed of the CPU might be reduced to very low values. When the temperature of the VRM is back within a safe range, the CPU clocks will be increased back to the expected values until the temperature limit is reached again. Internal tests at Noctua have shown that not all motherboards on the market are able to power the 250W models at prolonged full CPU load without the VRM running into thermal throttling. In case you experience the behavior described above please, check the VRM temperature (e.g. via HWinfo) and provide additional cooling to this area. In doubt, please contact your motherboard manufacturer for further information. Is it possible to use the cooler with vertical graphic cards? Depending on the chassis, card and motherboard being used, installing PCIe cards in a vertical position using riser cards may cause compatibility issues with CPU coolers. Whether there will be a problem or not depends on the exact position of the card (which is determined by the PC case and/or optional vertical GPU holder bracket), the width of the card as well as the position of the CPU socket on the motherboard. In order to verify that there is sufficient space for the cooler, please measure the distance between the centre of the CPU socket and the top of the PCI card in order to make sure that the cooler fits. 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. Which Noctua fan or CPU cooler should I buy? How to choose the right model? Not sure which Noctua product to buy? Our detailed buying guides for fans and CPU coolers help you to choose the model that works best for you. 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. 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. What Thermal Design Power (TDP) is this cooler recommended for and how much Watt (W) of heat can it dissipate? Please refer to our CPU compatibility list 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. 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. 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: Which Noctua coolers are compatible with Ryzen Threadripper 2? Please see our TDP guidelines for details. Even with a high-end cooler, the performance is not what I would expect, what can I do? First of all, please note that results in reviews might show different results as many tests are conducted in open test bench configurations outside a chassis, which allows a better supply of fresh air and thus allows the coolers reach lower temperatures than in a real-world setup inside a chassis. Secondly, processors emitting heat-loads of 180-250W or even more (with Turbo Boost) create more challenges for case ventilation than lower power mainstream CPUs as it is very difficult to remove so much heat from the chassis. For best performance, it is crucial that sufficient amounts of fresh air can enter the chassis and that warm air leaves the chassis as fast as possible. Internal testing at Noctua has shown that many PC cases are rather restrictive when it comes to air intake and exhaust due to dampening materials, doors, covers or a rather closed design approach in general. Increasing the number of system fans can help to a certain degree but will not provide much improvement if intakes and outlets are too resistive. The best cooling results are to be expected from cases which use a rather open approach (e.g. mesh walls and intakes). Unfortunately, Noctua cannot provide detailed recommendations for individual system configurations as there are too many options and variables available to give general recommendations. Please refer to general case cooling guidelines such as this one for information how to setup the airflow inside your case. 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. Do you have a question concerning one of our products? Please use this form to pose a question! Disclaimer:We create and update our compatibility lists with the utmost care. Unfortunately, mainboard manufacturers tend to change certain components and heatsinks without pointing it out by using corresponding revision names. If you run into problems while installing our coolers on one of the mainboards listed as being compatible, please don't hesitate to contact our support team at firstname.lastname@example.org.Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues.For use in systems from Dell, HP or Lenovo, please note this FAQ. Our case compatibility list helps you to quickly identify which PC cases offer sufficient clearance for which Noctua CPU coolers. The compatibility indication is based on the height of the coolers (including fans) as well as the maximum CPU cooler height specification given by the chassis manufacturer. Caution: Please note that the fans of some tower coolers (especially larger models with 140mm fans, e.g. NH-D15 or NH-U14S TR4-SP3) may overhang the RAM slots and that this can cause compatibility issues if RAM modules taller than 32mm are used. While the fans can be moved upwards to increase RAM clearance, this will increase the total height of the cooler and thus requires additional clearance inside the chassis. As a rule of thumb, if the fan overhangs the RAM, the maximum CPU cooler height specification of the case must be at least the size of the fan plus the height of the RAM minus 7mm (accounting for the height of the socket and CPU). For example, if a cooler uses a 140mm fan that overhangs the RAM and 46mm tall RAM modules are used, the max. CPU cooler height specification should be at least 179mm (140+46-7=179). For further information and instructions on how to move up the fan for each cooler model, please click the height specification link. Disclaimer: We create and update our compatibility lists with utmost care. However, case manufacturers sometimes change parts or details of their products without prior notice or explicitly indicating a revision. Therefore, Noctua cannot accept any liability, nor in any other way be held responsible, for the following compatibility information. When modern CPUs use their turbo modes, they can (depending on the configuration of the UEFI BIOS) dissipate much more heat than indicated by the manufacturer’s TDP (Thermal Design Power) specification. Just like manual overclocking, this puts higher demands on the cooling solution. Our CPU compatibility list helps you to choose the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned. We classify our coolers according to the following categories: best turbo/overclocking headroom medium turbo/overclocking headroom low turbo/overclocking headroom compatible without turbo/overclocking headroom compatible with certain restrictions (see comment) incompatible (see comment) For further information on CPUs exceeding their TDP ratings and how to configure the UEFI BIOS in order to avoid excessively high temperatures, please see this FAQ. Please also see our general buying guide, motherboard compatibility list and FAQs for further help on how to select the best cooler for your configuration.
