NH-U14S DX-3647 Opinión
Noctua NH-U14S DX-3647 является самым тихим кулером из тройки доступных вариантов. Конечно, он самый массивный, но именно благодаря этому мы можем использовать один тихий вентилятор, добившись минимального уровня шума – при максимальной скорости работы его не слышно, а при автоматическом управлении (800-900 об/мин) его не услышать даже наклонившись к системе в упор. Что касается эффективности, то она примерно равна NH-U12S DX-3647. Отличия заключаются в габаритах и в количестве вентиляторов, что и позволяет добиться равной эффективности. Если не брать во внимание габариты, то NH-U14S DX-3647 тише, даже если сравнивать максимальные обороты флагмана и автоматическое управление вентиляторами NH-U12S DX-3647.

NH-U14S DX-3647 Opinión
Noctua broke the mold with their new NH-U14S DX-3647 cooler. It can handle both narrow and square sockets with Noctua’s SecuFirm2 mounting system, and the oversized NF-A15 PWM fan excels at keeping the heatsink cool and makes little noise. If you are building a high-end Intel Xeon Scalable workstation for yourself or for your clients, you should look at these coolers.
Undoubtedly the Noctua NH-U14S DX-3647 heatsink is massive compared to most LGA3647 heatsinks. As a result, it will not fit most standard 4U workstation cases. We could not install the DX-3647 in our testing workstation based on a Supermicro SC747. This is a 4U workstation case as the NH-U14S is too tall. Our main workstation based on a Thermaltake Core X9 which is oversized for most users, it does handle the DX-3647 and has plenty of space left over.

NH-U14S DX-3647 Opinión
The SNK-P0068APS4 led to an average temperature of 31C at its full fan-speed while the Noctua NH-D9 DX-3647 4U had an average temperature of 23.5C with its fans at their full speed or 38.8C when using the automatic fan control enabled via the BIOS. The minimum and maximum core temperatures were also aligned with expectations. The Noctua heatsink did a nice job of allowing this Intel Xeon Silver CPU to run extremely cool inside this 4U chassis even at full load.
|

Resultado del análisis: "From compiling the Linux kernel to running Python scripts to the many other workloads tested, the Noctua Xeon Scalable 4U heatsink was doing a great job at keeping the system running cool, especially at full-speed but even with the automatic fan control it was doing a great job. Even at full-speed, the NF-A9 fans were barely audible outside of the steel Rosewill 4U chassis, especially if you are running multiple systems in the room." (Michael Larabel, Phoronix.com)

Does the NF-A15 PWM that comes with Noctua coolers run at a different speed (1500rpm) than the retail model (1200rpm)?
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 600 or 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 in the BIOS 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, by using 3rd party tools like IPMItool or IPMIutil, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply). Please note that any modifications performed with 3rd party tools are done at your own risk and that Noctua can not be held responsible for any possible issues.
I get a CPU fan error using my Noctua PWM fan, is it faulty?
My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?
- 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.
- 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:
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.
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.

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:
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.
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.
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.
I get a CPU fan error despite the fan is running!
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.
I have difficulties installing the cooler, can you help?
My case supports CPU coolers of up to XXXmm height, which model should I choose?
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?
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.
Is it possible to use the cooler with vertical graphic cards?
Which Noctua fan or CPU cooler should I buy? How to choose the right model?
