NH-U12P SE1366 Review

Yeni Corei7 işlemciler için özel dizayn edilen soğutucu testlerde oldukça başarılı olduğunu gösterdi. İşlemcimizi çalışma anında düşük sıcaklılarda tutarken bu görevi 2 fan çalışmasına rağmen oldukça sessiz yerine getirdi. Özellikle işlemcimizi overclock yaptığımda ve load durumunda soğutucuda bulunan 2 fan o kadar sessiz çalışıyordu ki powersupply ve kasa fan seslerini çok rahat ayırt edebiliyordum. Mükemmel bir ısı taban tasarımı kullanan Noctua bu tasarıma 2 adet başarılı fan ve kaliteli termal macun ekleyerek çok iyi ve performans açısından oldukça başarılı bir ürün elde etmiş.
Test verdict: "Yüksek performansı, kullanılan malzemenin yüksek kalitesi, zengin kutu içeriği ile TurkChip The Best ödülünü hak eden çok başarılı bir ürün." (Murat Yildirim, Turkchip.com)

NH-U12P SE1366 Review

Well the NH-U12P 1366 seems to have done just as well as the NH-U12P did on LGA775, it jumps straight to the top of the LGA1366 coolers that we have tested. Even though intel processors generally use very little power during idle, it’s still a difference enough for the Noctua cooler to jump a couple of degrees ahead of the competition. And putting the heat up on load just lets the NH-U12P 1366 run away from the other coolers tested here even more. It’s close to being twice as good as the stock Intel cooler (this one was pushing 80oC on the CPU we had!), so if you’re running on a stock Intel cooler it’s going to make a huge difference to get an aftermarket cooler.
Test verdict: "Well I’m happy to say the NH-U12P SE1366 continues the legacy laid down by the NH-U12P before it, and is sure to go on to receive just as many awards as its original LGA 775 version did. Even with the addition of a second fan the cooler remains pretty quiet overall, and is easily drowned out by case fans etc. For someone that loves a quiet computer (like me), this is something to fall in love with."

NH-U12P SE1366 Review

Der NH-U12P verrichtet seine Arbeit auf beeindruckende Weise. Zuverlässig kühlt er den Prozessor auch bei hohen Belastungen und das ohne nervige Lüftergeräusche. Die Verarbeitung des Kühlkörpers ist, wie man es bei Noctua eigentlich nicht anders kennt, von hoher Qualität. Die Premuim-Lüfter NF-P12 haben schon in anderen Tests bewiesen das sie eine hervorragende Wahl zur Kühlung darstellen. Zusammengefasst kann man Noctua nur zum NH-U12P CPU-Kühler gratulieren.
Test verdict: "Das Herzstück des Rechner ist zweifellos der Prozessor. Und um dessen Kühlung sollte man sich schon Gedanken machen. Legt man diese Kühlung in die Hände des Noctua NH-U12P CPU-Kühlers aus dem Hause Noctua, dann kann man sich sicher sein das der Prozessor in den besten Händen ist." (Dirk Löbe, Dirks-Computerecke.de)

NH-U12P SE1366 Review

As you can see, they are very close. I am very hesitant to say one cooler did better than the other. However, since they TRUE 120 has commonly been called "the best" it looks really great for Noctua here. The NH-U12P definitely competes with the TRUE 120 very well!!
Test verdict: "Overall I am impressed with the NH-U12P from Noctua. It is easy to install, it does what it should, and it does it VERY well. With the 2 included fans, this cooler is ready to go out of the box. And since they are Noctua fans you know they are quiet." (Austin Thorne, TechArkade.com)

NH-U12P SE1366 Review

We know from when we tested the original Noctua a few months ago that we were in for a good showing from this new cooler. We were not disappointed at all. With the aid of the dual NF-P12 fan, we were able to equal the performance of the Thermalright T.R.U.E. with dual fans and to top other top coolers in the original configurations. [...] The updates that we see with the SE1366 is what makes this cooler better than the previous version. The mounting system is simple and takes a little time consumption when installing, but works well and is worth the little extra time that it takes to assemble. And we can't forget the individual fan that you get with the SE1366. The added couple of degrees is also worth it. Especially when you are trying to get the highest stable overclock from your CPU and also want to remain in quiet trying to get there. Noctua planned everything out when developing the upgrades to the NH-U12P.
Test verdict: "I have echoed this in every Noctua review I have ever done and that is the quality that you get from Noctua can't be touched by many in the industry. The SE1366 continues the excellence we see from Noctua." (Tony Day, Pro-Clockers.com)

NH-U12P SE1366 Review

I grafene over er NH-U12P testet slik den kommer rett ut av boksen. Her sklir kjøleren rett til topps uten problemer. Den plasserer seg mer enn 2 solide grader foran kjøleren som frem til nå lå med topplasseringen ved 90 W belastning. Når vi skur opp belastningen til 120 W beholder Noctua fortsatt det tydelige forspranget i testen.
Test verdict: "Noctua har med deres NH-U12P SE1366 nok en gang konstruert en soleklar testvinner. Ytelsen er eksepsjonell, kjøleren sitter meget godt på hovedkortet og det følger med mye nyttig tilbehør." (Jørgen Elton Nilsen, Hardware.no)

NH-U12P SE1366 Review

Load conditions really showed something interesting as the cooling performance was in a different league to most other coolers on the market, which might be due to the quantity of the fans coupled with the very well made heat sink. Compared to the stock cooler with an average of 49°C and a peak temperature of 53°C, the NH-U12P pulled of an amazing 46° with an average of 43°C, making it the best Core i7 cooler we’ve tested so far, beating our previous product review.
Test verdict: "The NH-U12P is a top class cooler guaranteed to impress and just crushes the competition. We would say: Go buy one now!" (Farhan Khan, Tech-Lobby.com)

Installation Manual (PDF)

Information Sheet (PDF)

Is the high weight dangerous for the CPU or socket?

No. Noctua coolers possess an extremely reliable SecuFirm™ mounting system. Thanks to the screw connection with the backplate on the rear side of the motherboard, the exceedance of the weight recommendations by Intel and AMD common among high-end coolers is completely unobjectionable.

Is it possible to mount fans with a greater height than 25mm?

Yes. The fan mounting clips grip to the screw holes in the lower edge of the fan frame and hence work with all fans regardless of their height. However, problems with the mounting of the fan can occur due to other parts within the case or fans with special frame designs, where the clips can't grip to the screw holes in the lower edge of the frame.

NH-U fan mounting

Is it possible to run two fans at a time?

Yes. Using the 4 supplied fan clips, you can mount two 120mm fans on the NH-U12(F/P) and two 92mm fans on the NH-U9(F/B).

Should the fan be mounted sucking away from the heat-sink or blowing onto the heat-sink?

Please install the fan blowing onto the heat-sink.

NH-U Airflow

If you're using two fans, please install them so that one blows onto the heat-sink and the other sucks the air away from the other side.

On which side of the heat-sink should the fan be installed?

Please install the fan so that the hot air can be disposed as good as possible either through the rear case fan (Airflow Option 1) or through the power supply (Airflow Option 2).

NH-U Airflow

Is it possible to cool my CPU without a fan (passive) using Noctua coolers?

Noctua coolers weren't originally designed for passive operation although the cooling performance is sufficient in many cases. Unfortunately, it is impossible for us to indicate whether a certain CPU can or cannot be cooled without a fan, as this depends on various factors such as case temperature, case ventilation or the orientation of the socket. Generally, we recommend using a fan in the first instance and then lowering RPM while constantly monitoring the temperature.

How to install the fan using the supplied steel clips?

First hook the clip into the notch of the heatsink:

Vibration Compensators Installation

Then hook the endings of the clips into the mounting holes of the fan:

How much clearance for RAM or chipset coolers does the NH-U12P provide?

The NH-U12P provides 40mm clearance for near-socket components:

Vibration Compensators Installation

What can I do if the fan blocks my RAM or chipset cooler?

In order to increase clearance, you can easily move the fan up a few fins as show below:

Vibration Compensators Installation

I've got 2 adapter cables with the cooler. What's the difference between these cables?

The Low-Noise-Adapter (L.N.A.) and Ultra-Low-Noise-Adapter (U.L.N.A.) reduce the speed of the fan to 1100 / 900 rpm:

Vibration Compensators Installation

Can I use Noctua fans on my fan controller?

Our fans are compatible with the vast majority of fan controllers on the market. However, there is a compatibility issue with a few models such as the Zalman ZM-MFC2 and Bitfenix Recon, which apply Pulse Width Modulation (PWM) on the 12V line and use an unfavourable PWM carrier frequency. This can create an oscillation when used with certain fans, which will result in the fan speeding up and down. We therefore recommend not using the Zalman ZM-MFC2 or Bitfenix Recon with our fans.

I can’t spread the thermal compound by turning the cooler as described in the manual!

Due to the new LGA mounting bars with screw threads that facilitate the installation process, there's little room to turn the cooler as described in step 4 of the supplied manual. There's nothing to worry about though, as you can still turn the cooler by a few millimetres in order to help the thermal compound spread. We've also made the compound slightly less viscous so that the contact pressure of mounting system is wholly sufficient to spread it.

My fan doesn’t spin when I start up the PC - is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.

Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?

You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.


Help, the base of the cooler doesn’t make contact with the CPU / there is no contact pressure!

Please verify that you have installed the fastening brackets correctly:

Fastening Brackets

How can I connect 2 fans?

When using 2 fans, please connect one of the fans to the CPU-Fan header and the second fan to one of the Case-Fan headers of your mainboard. Alternatively, you can also use a 3-pin Y-cable in order to run both fans via the CPU-Fan header. Such cables are available in specialised retail stores.

The fan doesn’t start with the Ultra-Low-Noise Adaptor (ULNA)!

Unfortunately, many Gigabyte mainboards use a special control circuit that can lead to start-up problems in conjunction with the Ultra-Low-Noise Adaptor (ULNA). This control circuit remains active even when automatic fan control is disabled in the BIOS. In these cases, please use the fan without the ULNA or connect it directly to the power supply (or an external fan controller) in order to ensure reliable operation with the ULNA.

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.

My unlocked Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?

Intel's unlocked CPUs (K, X and C suffix) can dissipate more heat than indicated by the TDP specification if
  1. the TDP limits are extended or disabled in the motherboards' BIOS.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
  3. some software creates untypical loads, e.g. Prime95 with AVX2 support and a) and/or b) apply.

This can lead to temperature issues, especially when using smaller coolers or compact cases.

The actual power draw of the processor can be monitored with software provided by the motherboard vendor or with 3rd party tools like HWInfo or HWMonitor.

If you encounter temperature issues (>90°C) and notice a higher than specified power draw, please ensure that no automatic overclocking is applied and limit the TDP to the specified value by choosing appropriate BIOS settings.

For Kaby Lake CPUs, it may also help to lower the CPU clock speed for applications that heavily use the AVX instruction set, which can lead to higher loads and power draw. This option is usually referred to as “AVX offset” and makes it possible to lower the multiplier specifically for AVX based applications without reducing performance when using other instruction sets. Depending on the quality of the CPU and the programs being used, a reduction of 2-3 steps usually gives very good results.

Please contact your motherboard vendor for details if you have trouble finding the appropriate settings in the BIOS.

All our TDP recommendations are based on thorough testing with the default values specified by Intel using popular applications such as Asus Realbench and prime95. Please note, however, that prime95 creates a particularly high load that goes beyond typical application scenarios and this leads to elevated temperatures. We thus recommend using other programs such as Realbench for checking the stability and temperatures of the CPU in realistic scenarios.
