NH-U12S SE-AM4 Review

Passando all’NH-U12S, vediamo un repentino “drop” nelle temperature registrate, a fronte di un prezzo superiore ed un ingombro maggiore, con una ventola ugualmente silenziosa, la ormai famigerata NF-F12 PWM, ventola dall’ottimo bilanciamento tra airflow e pressione statica e dalle innumerevoli soluzioni tecniche che la rendono forse la miglior ventola di sempre.
Test verdict: "Il Noctua NH-U12S SE-AM4 è forse il dissipatore perfetto per ogni esigenza (a parte per i sistemi ITX, dove proprio l’NH-L9x65 è la scelta appropriata), ed il prezzo “contenuto” (stiamo parlando sempre di Noctua, e se prendiamo il costo della sola NF-F12 PWM, sono già 20€) insieme alle prestazioni elevate ci portano a dare ad esso il nostro Hardware Diamond Award."

NH-U12S SE-AM4 Review

With the popularity of Ryzen there is a huge push to have plenty of cooling options on the market. What makes Ryzen so interesting is the 65w TDP making it one of the coolest performance CPUs on the market. This translates into systems that don’t require large CPU coolers and can finally get away with passive designs and still throw down a decent overclock. As always the installation hardware is extremely good and features a universal mounting system that is both easy to install and works on almost every Noctua cooler.
Test verdict: "Overall performance was really good. The heat tests showed that the Noctua NH-U12S SE AM4 could handle a very healthy overclock and responded well to having two fans installed in push-pull." (Dennis Garcia, HardwareAsylum.com)

NH-U12S SE-AM4 Review

El cooler Noctua U12S SE-AM4 ofrece unas fantásticas prestaciones dejando que el procesador AMD RYZEN 5 1600X sólo sobrepase ligeramente los 40ºC en máximo rendimiento como hemos podido comprobar, lo que habla y muy bien del excelente trabajo que ha hecho Noctua con este cooler. Si las prestaciones han sido fantásticas, también lo ha sido la bajísima sonoridad del ventilador Noctua NF-F12 PWM, que a máximas revoluciones sólo produce 22.4 dB(A), pero no por ello el caudal de aire baja de los más de 90 m3/h.
Test verdict: "En definitiva, si buscas un nuevo cooler para sustituir el ventilador de serie de tu AMD Ryzen, este modelo Noctua U12S SE-AM4 es una opción sobresaliente por rendimiento y bajísima sonoridad." (Ana Rey Carballeira, Razorman.net)

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 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 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.

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.

Which Noctua CPU coolers are compatible with Intel LGA2066?

Due to the heatsink mounting mechanism being identical on LGA2011 and LGA2066, Noctua’s SecuFirm2™ mounting systems for LGA2011 also support Intel’s upcoming ‘Basin Falls’ X299 HEDT (High End Desktop) platform for ‘Skylake-X’ and ‘Kaby Lake-X’ processors. Most current Noctua coolers already include SecuFirm2™ mounting systems for LGA2011 and can thus be used on LGA2066 motherboards without any upgrades or modifications.

The following models include a mounting-kit for socket LGA2011/2066 and are thus compatible out of the box:

NH-C14S
NH-D14 SE2011
NH-D15
NH-D15S
NH-D9L
NH-L12
NH-L9x65
NH-U12S
NH-U12DX i4
NH-U14S
NH-U9DX i4
NH-U9S

The following models can be made compatible with the LGA2011/LGA2066 sockets free of charge using the NM-I2011 upgrade-kit:

NH-C12P
NH-C12P SE14
NH-C14
NH-D14
NH-D15 SE-AM4
NH-U12S SE-AM4
NH-L9x65 SE-AM4
NH-U12
NH-U12F
NH-U12P
NH-U12P SE1366
NH-U12P SE2
NH-U9
NH-U9B
NH-U9B SE2
NH-U9F

The following models can be made compatible with the LGA2011/LGA2066 sockets using the NM-I2011 upgrade-kit but are not eligible for Noctua‘s free mounting offer, so users have to purchase the kit at local resellers:

NH-U12DO (Note that the A3 version is not compatible!)
NH-U12DX
NH-U12DX 1366
NH-U9DX 1366

The following models are not compatible with the LGA2011/LGA2066 sockets and can not be upgraded:

NH-L9a
NH-L9i
NH-U12DO A3
NH-U9DO A3

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

Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one?

Most Noctua SecuFirm™ mounting parts are cross-compatible, so if you’re replacing one Noctua cooler with another, it is usually possible to keep the original backplate and/or mounting system in place in order to re-use it for the new cooler. If you had your previous Noctua cooler installed on an Intel LGA115x (LGA1156, LGA1155, LGA1151, LGA1150), LGA2011 (LGA2011-0, LGA2011-3) or LGA1366 system and replace it with an NH-U14S, NH-U12S or NH-U9S, you only need to replace the original mounting bars with the NM-IMB3 ones supplied with the new cooler. For all other models, you can keep the entire mounting system in place on the aforementioned Intel sockets. On AMD AM2, AM2+, AM3, AM3+, FM1, FM2, FM2+, you only need to replace the original mounting bars with the ones supplied with the new cooler.

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.

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.

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 where 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.

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

The following models include a mounting-kit for socket AM4 and are thus compatible out of the box:

NH-D15 SE-AM4
