    Noctua NH-D14 FAQs

    Le poids élevé représente-t-il un danger pour le processeur central ou le socle ?
    Non. Les refroidisseurs Noctua disposent d'un système de montage SecuFirm™ très fiable. Grâce au vissage sûr avec une plaque de montage au dos de la carte mère, le dépassement des recommandations de poids données par Intel et AMD, qui est normal pour les refroidisseurs high end, ne présente pas de danger et est sans inconvénients.

    Est il possible de refroidir mon CPU sans ventilateur (passif)?
    Radiateurs Noctua n’sont pas conçus à l’origine pour des opérations passives quoique la performance du refroidisseur soit suffisante dans beaucoup de cas. Malheureusement, il nous est impossible de vous indiquer quelles sont les CPU qui peuvent ou qui ne peuvent pas être refroidir sans ventilateur, car il dépend de nombreux facteurs comme la température, la ventilation ou orientation du socket. Généralement, nous recommandons, dans un premier temps, utiliser le ventilateur et de diminuer progressivement RPM en surveillant constamment la température.

    Pourquoi le fond du refroidisseur Noctua n'est-il pas brillanté et poli ?
    Etant donné que la plupart des enthousiastes d'ordinateurs personnels utilise encore aujourd'hui des pâtes thermiques à forte viscosité, le fond du refroidisseur Noctua a été optimisé pour l'utilisation de ces pâtes. Les fines rainures (micro-grooves) dans la surface du fond du refroidisseur Noctua permettent d'appliquer les pâtes thermiques à forte viscosité de manière homogène en une couche ultramince et sans aucune inclusion d'air n'existe entre le refroidisseur et la processeur central. Le risque d'une application non homogène serait beaucoup plus élevé si la surface était brillantée et polie. Des couches de pâte thermique trop épaisses et des inclusions d'air altérant sensiblement la transmission calorifique, les micro-rainures sont d'une importance décisive pour la performance de refroidissement totale du refroidisseur Noctua en cas d'utilisation des pâtes thermiques courantes à forte viscosité.

    Can I use Noctua fans on my fan controller?
    In general, our fans can be used with any fan controller. There is a known compatibility issue with the Zalman ZM-MFC2 controller though: This product uses Pulse Width Modulation (PWM) in order to control the fan speed and the unfavourable carrier frequency of the PWM signal can create an oscillation when used with certain fans. This will result in the fan speeding up and down. We therefore recommend not using the Zalman ZM-MFC2 with our fans.

    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 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.


    How can I check whether my case is wide/high enough for the cooler?
    In order to check whether the cooler isn’t too high for your case, please 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.

    Is the cooler compatible with LGA1366 mainboards for Xeon 5500?
    Due to the custom NM-I3 backplate, the cooler can not be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). Please choose our NH-U12DX 1366 for these mainboards.

    1366 compatibility

    My mainboard has more than one set of mounting holes. Which one should I use?
    Please always use the standard set of mounting holes that's compliant with your socket type (e.g. 75mm LGA1156 hole spacing on LGA1156 sockets) and parallel to the sides of the socket. Don't use mounting holes which are rotated in relation to the socket.

    1366 compatibility

    I can't open the socket due to the mounting bars!
    Please first loosen one of the two thumbscrews that hold the mounting bars in place. Then untighten the second screw so that you can swivel the mounting bar and open the socket. Depending on the position of the mounting bars, you may need to swivel both.

    Can the cooler be installed turned by 90° on AMD sockets?
    No. The new SecuFirm2™ mounting system for AM2, AM2+ and AM3 uses the same standardised hole spacing as the Intel system and thus allows for a much easier installation, but the cooler cannot be installed turned by 90°.

    Does the package include a backplate for AMD AM2(+)/AM3(+)/FM1/FM2(+)?
    No. As most AMD mainboards come with a stock backplate preinstalled, the cooler doesn’t include an AMD backplate. If your mainboard doesn’t have a backplate, please contact our support team at

    How much clearance for RAM or chipset coolers does the NH-D14 provide?
    The NH-D14 provides 44mm clearance for near-socket components:

    Can I use Corair Dominator RAM with the NH-D14?
    The NH-D14 is a large cooler that extends over the RAM slots on most mainboards. While DDR2 Corsair Dominator don't fit underneath the cooler, DDR3 Corsair Dominator do fit when the removable top heatsink is taken off as shown below. Please also note that the NF-P12 fan can be moved upwards or taken off in order to improve RAM compatibility as shown here.


    Can I install 3 fans?
    The cooler doesn’t include mounting hardware for a third fan as most setups will have a chassis fan right behind the cooler. In this case, adding a third fan to the heatsink doesn’t offer a measurable performance benefit and can lead to acoustic disadvantages.

    Can I install 38mm depth fans?
    As the distance between the two radiators is only about 28mm, you can’t install fans with more than 25mm depth. It’s possible to install such fans on the front side of the cooler though.

    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 independent from the second fan’s rpm signal.

    The fan clips are almost touching my VGA card!
    On some mainboards, the fan clips may be very close to the rear side of VGA cards installed in the first PCI-E slot. Please insulate the fan clips using duct tape or shrink-on tubes in this case.


    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.

    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.

    Is the mounting system compatible with LGA1155?
    Yes. LGA1155 uses the same hole spacing as LGA1156, so the same SecuFirm2™ mounting system can be used.

    How can I check whether my AMD mainboard has a standard AMD backplate that’s compatible with the SecuFirm2™ mounting system and how should I proceed with the installation?
    The SecuFirm2™ mounting system requires a standard AMD backplate (either plastic or metal) with screw threads as shown on the pictures below. These backplates are pre-installed on the rear side of most AMD mainboards (see first picture below) and fixed to the retention module with four screws (see second picture below). If your retention module is fixed with plastic bolts instead of metal screws, please contact in order to obtain an appropriate backplate.

    In order to proceed with the installation of your Noctua cooler, please remove the four screws and the retention module but keep the backplate in place so that you can see the screw threads from the top side of the motherboard (see third picture below). You can then proceed with the installation of the SecuFirm2™ mounting kit as described in the manual (see fourth picture below).

    How to remove the base protection cover?
    Noctua CPU coolers are shipped with a plastic protection cover at the bottom side of the cooler, which protects the contact surface against scratches and other damage.

    The base of Noctua CPU coolers is made from hard-wearing nickel plated copper, so there's nothing to worry about if you buy a Noctua cooler from second hand or if your cooler didn't come with a protection cover. Please proceed with the installation as explained in the manual.

    You can simply remove the cover as shown below:

    Base Protection Cover

    Is the cooler compatible with AMD AM3+ and FM1?
    As the hole spacing for CPU cooler installation on AM3+ and FM1 is the same as on AM2, AM2+ and AM3, the cooler is fully compatible with AM3+ and FM1 out of the box and doesn’t require any modifications or upgrades.

    Is the cooler compatible with the Intel LGA2011 socket and Asus X-socket™?
    The cooler doesn’t come with LGA2011 mounting hardware out of the box, but it can be upgraded to support LGA2011 via the NM-I2011 mounting kit.

    Please also note that the cooler is fully compatible with Asus Rampage IV series LGA2011 motherboards that feature Asus X-socket™. Asus X-socket™ models use an interchangeable backplate that makes it possible to install LGA1366 heatsinks, so the cooler is fully compatible with these mainboards out of the box and does not require any upgrades to be installed.

    Asus X-socket

    In order to install the cooler on Asus X-socket™ mainboards, please first remove the mainboard’s LGA2011 backplate and install the LGA1366 backplate supplied with the mainboard instead (see the mainboard manual for detailed instructions). Then install the Noctua cooler as described in the supplied installation manual for LGA1366. In case you’ve lost the printed installation manual, you can download it here.

    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. 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.

    Can use the NF-A15 fan on my Noctua CPU cooler?
    The NF-A15 is fully compatible with the NH-U12P, NH-C12P and NH-C12P SE14. On the NH-D14 and NH-C14, the NF-A15 fan can only be installed using optional fan clips. For this, please contact our customer service.

    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.

    Is the cooler compatible with AMD FM2+?
    As the hole spacing for CPU cooler installation on FM2+ is the same as on AM2, AM2, AM3(+), FM1 and FM2, the cooler is fully compatible with FM2+ out of the box and doesn’t require any modifications or upgrades.

    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.
