NH-U12P SE1366 Review
In the NH-U12P’s dual fan configuration it was clearly the winner with a 1.75*C gap between it and the closest competitor, the Monsoon III LT. The NH-U12P SE1366 cooled our i7-920 to a very nice 56.25*C under full load, and a whopping 17.75* under stock. [...] With the system overclocked to 3.5GHz and under full load the stock cooler starts to scream for mercy as the load temp climbed to 83.5*C. The Vigor Monsoon III LT dropped back 2 spots, and the NH-U12P is still in the lead, keeping our i7-920 to a toasty 67.5*C; a whole 16* cooler then stock. [...] the Noctua NH-U12P CPU Cooler is the winner in our testing. Either in its original single fan configuration or in its new SE1366 dual fan configuration it led the pack and did it quietly.
|
|||||||
Test verdict: "The Intel Core i7 CPUs can get very toasty so the need of a quality cooler is a must. The Noctua NH-U12P is just that and will continue to be our King of Cooling." (Shane Higgins, LegitReviews.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
Au final, la meilleure solution est le système Noctua NH-U12P livrée d'origine avec deux ventilateurs de 120 millimètres. En observant ses points, il est à chaque fois le meilleur compromis performances/nuisances sonores. Il est bien évidemment audible en 12 volts mais quand on observe ses performances en mode Mid, on se dite que cela suffit amplement pour refroidir le plus chaud des Core i7. Même le mode Low est plus qu'envisageable, le tout dans un silence de cathédrale.
|
|||||||
Test verdict: "Si ce dissipateur Intel ne vous suffit pas, nous vous conseillons le Noctua NH-U12P SE1366 à 60 euros qui certes coûte une dizaine d'euros de plus que le Thermalright et le Zalman mais qui en contrepartie offre un bundle hyper complet avec deux ventilateurs de 120 mm, des câbles réducteurs de tension et de la pâte thermique de qualité."

NH-U12P SE1366 Review
With the fans at standard speed, our overclocked and overvolted Core i7 ran 19°C cooler with the Noctua than with the reference Intel HSF, while producing a negligible low hum. Using the black fan adaptors, the Noctua lost no cooling ability and was a touch quieter.

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."

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

My unlocked Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?
- the TDP limits are extended or disabled in the motherboards' BIOS.
- the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
- 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.
Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one?
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.

How should I clean my Noctua cooler?
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?
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.
My case supports CPU coolers of up to XXXmm height, which model should I choose?
I have difficulties installing the cooler, can you help?
How much torque should be applied when tightening the screws of a Noctua CPU cooler?
Screw type | Max. torque |
---|---|
NM-SSC1 screws for fixing the fastening brackets to the base of the heatsink | 0.5 Nm |
NM-ITS1 thumb screws for fixing Intel mounting bars | 0.5 Nm |
NM-ALS1 screws for fixing AMD mounting bars | 0.6 Nm |
Spring-loaded screws for fixing the heatsink to the mounting bars | 0.6 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.
Why is my Ryzen 3000 processor getting so hot? Why are Ryzen 3000 CPUs running hotter than previous generation Ryzen CPUs with the same TDP rating? Is there anything wrong with my cooler?
The latest Ryzen 3000 processors (except APU models) differ from previous Ryzen generations in that they are no longer based on a single, large chip but use a multi-chip approach with smaller chips instead. Depending on the exact model there can be one (6 and 8-core models) or two (12 and 16-core models) actual CPU-Dies (CCD) on the package. Each processor also uses an I/O-Die (IOD), which contains things like the memory controller, PCIe controller, connections to the motherboard chipset and other functions.

Because of this design change and the switch to a smaller 7nm manufacturing process, the heat distribution of the overall processor is much different from older 14nm and 12nm based single-chip Ryzen processors with a similar power draw.
Depending on the exact CPU model, its specified TDP value and possibly extended power limits (precision boost overdrive), a single CPU-die can create a heatload of up to 130W easily, whereas the I/O-die usually creates a heatload of about 10W. Due to the small size of the CPU-die, the heat density (W/mm²) of this chip is very high. For example, a 120W heatload at a chip-size of 74mm² results in a heat-density of 1.62W/mm², whereas the same heatload on an older Ryzen processor with a chip-size of 212mm² gives a heat-density of just 0.57W/mm².
This large difference in heat-density is the reason why newer Ryzen 3000 processors become much warmer at similar heatloads than their predecessors.
Furthermore, Ryzen 3000 CPUs are using the rated temperature headroom (up to 95°C) quite aggressively in order to reach higher boost clocks. As a result, it is absolutely no problem and not alarming if the processor runs into this temperature limit. The clock speed and supply voltage will be adjusted automatically by the processor itself in order to remain within AMD’s specifications and to prevent overheating.
Due to the higher heat density, higher thermal limits and more aggressive boost clock usage, it is perfectly normal that Ryzen 3000 CPUs are reaching higher temperatures than previous generation Ryzen CPUs with the same TDP rating. Higher CPU temperatures are normal for Ryzen 3000 processors and not a sign of that there is anything wrong with the CPU cooler.
