NH-U14S TR4-SP3 Opinión

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.
Resultado del análisis: "Der U14S ist im direkten Vergleich der mit Abstand leistungsfähigste Kühler. Er schafft es dabei auch den derzeit stromhungrigsten AMD Desktopprozessor bei 3850MHz auf Temperatur zu halten. Hierbei verbrauchte das Testsystem ca. 365 Watt an Strom. Ein Wert der diverse Gamingrechner verblassen lässt. Sollte also der Platz vorhanden sein, trifft man mit dem Noctua NH-U14S die derzeit beste Entscheidung. Durch seinen tadellosen Auftritt hat sich der U14S auch unseren Enthusiast Award verdient." (Markus Lakner, Hardwaremax.net)

NH-U14S TR4-SP3 Opinión

Mit einem Blick auf das erzielte Testergebnis wird man schnell feststellen, dass der NH-U14S TR4-SP3 die Thermaltake Floe Ring RGB 360 AiO-Wasserkühlung, welche sich im Lieferumfang des Threadripper Media-Kits befindet, in den Schatten stellt. Wenn man sich einmal die Radiatorfläche von 360 mm anschaut, welche einem diese AiO-Wakü bietet, so kann man vor dem NH-U14S TR4-SP3 nur den Hut ziehen, denn die erreichte Kühlleistung ist nicht nur beachtlich, sondern wird auch bei einer angenehmen Geräuschkulisse erreicht. Für den Vergleich mit der herangezogenen AiO-Wakü muss jedoch noch erwähnt werden, dass die Bodenplatte hierbei nicht den gesamten Heatspreader bedeckt.
Resultado del análisis: "Mit dem NH-U14S TR4-SP3 hat Noctua einen Kühler in sein Sortiment aufgenommen, welcher trotz seiner schlanken Bauform und einem einzelnen Lüfter eine sehr gute Leistung erzielt hat. Durch die erreichte Kühlleistung kann der Kühler auch problemlos auf einer übertakteten CPU eingesetzt werden, denn der Kühler stellt selbst eine 360-mm-AiO-Wasserkühlung (mit einer kleineren Bodenplatte) in den Schatten. Die Verarbeitung des Kühlers sowie auch des mitgelieferten Lüfters ist auf einem sehr hohen Niveau." (Patrick Seus, mod-your-case.de)

NH-U14S TR4-SP3 Opinión

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!
Resultado del análisis: "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-U14S TR4-SP3 Opinión

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.
Resultado del análisis: "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)

¿Por qué la base de los disipadores Noctua no tiene un acabado pulido como un espejo?

Teniendo en cuenta que mayoría de los entusiastas del hardware usan compuestos térmicos de alta viscosidad, la superficie de la base de los disipadores Noctua se ha optimizado para el uso de este tipo de pastas térmicas. Las micro-hendiduras de la superficie de la base de los disipadores Noctua aseguran que los compuestos térmicos de alta viscosidad se dispersen de manera uniforme en una fina capa por toda la zona de contacto y que no queden huecos entre el disipador y la CPU. Con un acabado pulido como un espejo, el riesgo de una dispersión desigual es mucho más alto. Dado que las capas demasiado gruesas de pasta térmica y los huecos con aire deterioran dramáticamente la transferencia térmica, las micro-hendiduras son de vital importancia en el rendimiento general de los disipadores Noctua cuando se usan con compuestos térmicos de alta viscosidad.

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.

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.

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.

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).
