Is the cooler compatible with all LGA1366 mainboards?

The DX models (NH-U12DX i4, NH-U9DX i4, NH-U12DX 1366, NH-U9DX 1366) can only be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). The cooler is thus incompatible with Xeon 3500 and Core i7 mainboards that don’t have such a backplate. Please choose our normal retail models with LGA1366 support (or NM-I3 kit) for these mainboards.

Buying guide: Which Noctua CPU cooler should I buy?

Noctua offers a wide selection of CPU coolers for various demands and purposes. Use the following criteria to select the model that works best for you:

  1. CPU socket: Which CPU socket are you using? Select a cooler model that fits your socket using our socket compatibility chart.
  2. Motherboard: Which motherboard are you using? Select a cooler model that fits your motherboard using our motherboard compatibility list.
  3. CPU TDP (Thermal Design Power), overclocking and noise: Which CPU are you using? Do you want to overclock? Do you want your system to run as quietly as possible?
    As a rule of thumb, the bigger a cooler is, the bigger is its cooling performance: Whereas some of our compact, low-profile cooler models are only suitable for lower TDP CPUs, the bigger models are ideal for high TDP CPUs and overclocking.
    Also note that cooling performance and noise go hand in hand: By choosing a cooler that offers plenty of performance headroom for your CPU, you will be able to run the fan(s) at very low speeds and noise levels. By contrast, if you choose a cooler that will be fully maxed out by your CPU, the fans will run at higher or maximum speeds more often when your CPU is under full load.
    Please refer to our CPU compatibility list for detailed information and select a cooler that fits your CPU’s TDP class, possible overclocking ambitions and demands on quietness of operation.
  4. Case compatibility and cooler height: Different PC cases offer different amounts of clearance for CPU coolers. Please refer to the case manufacturer’s website to check the specified clearance for CPU coolers or measure the clearance if you already have the case at hand. You can then select a cooler that will fit your chassis using our by referring to the height specifications on the individual product pages of our website.
  5. RAM compatibility: With some of our bigger cooler models, either the heatsink itself or one of the fans may overhang the RAM slots on some motherboards. This is not a problem with standard height RAM modules (up to 33mm), so as long as you stick to these, you won’t have to worry about RAM compatibility at all. It can, however, limit the compatibility with memory modules that feature taller heat-spreaders (more than 33mm height). If you would like to use RAM with taller heat-spreaders, please check our remarks regarding RAM height restrictions in the cooler descriptions and choose an appropriate cooler model. For example, the NH-D15S is compatible with RAM modules of up to 64mm height, and popular models such as the NH-U12S, NH-U9S and NH-D9L are compact enough not to overhang the memory slots at all and thus offer 100% compatibility with RAM modules of any height.
  6. PCIe compatibility: On some motherboards, bigger coolers may overhang the top PCIe slot. Note that this depends both on the size of the cooler and on the location of the CPU socket and top PCIe slot on the motherboard. For example, coolers with 120mm or 92mm size fans generally don’t overhang the top PCIe slot on ATX or µATX size motherboards. On ITX motherboards, where the CPU socket is often closer to the PCIe slot, coolers with 120mm size fans may overhang the slot. Please refer to our motherboard compatibility list to check which coolers overhang the top PCIe slot on a given motherboard. Models such as the NH-U9S, NH-D9L, NH-L9x65 and NH-L9i are compact enough not to overhang the top PCIe slot on any motherboard and thus offer full compatibility in all cases.
  7. Popular choices and recommendations: Still undecided? Here’s a list of our most popular models that have proven to work extremely well for the vast majority of users:
    • NH-D15: our flagship model, providing the best possible performance for overclocking and silent-enthusiasts. Check case, memory and PCIe compatibility though.
    • NH-D15S: performs very close to the NH-D15 but offers full compatibility with RAM modules up to 64mm height and has hardly any PCIe compatibility restrictions on ATX and µATX size motherboards.
    • NH-U12S: excellent quiet cooling performance for up to 165W TDP and moderate overclocking, 100% RAM compatibility and 100% PCIe compatibility on ATX and µATX size motherboards.
    • NH-U9S: good quiet cooling performance for up to 165W TDP, mild overclocking with lower TDP CPUs, only 125mm height, 100% RAM compatibility and 100% PCIe compatibility on ITX, ATX and µATX size motherboards.

TDP guidelines & cooler height

In order to be able to provide you with detailed recommendations for each individual CPU model, our general TDP guidelines have been replaced with our CPU compatibility list. Please refer to the list for help on how to choose the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned.

If you can not find a particular CPU model in the database, please contact us at support@noctua.at.







This chart provides information about the basic mechanical compatibility of our coolers with CPU sockets complying to the official Intel or AMD specifications. Please note that irrespective of the basic mechanical compatibility with a given socket and depending on the individual configuration, certain mainboards or other components may pose problems. The fact that the cooler is mechanically compatible with a given socket thus provides no guarantee that it can be used on each system that is based on this socket. This also includes the possibility that some processors' power dissipation may exceed the capacity of compact cooler models (e.g. NH-L9, NH-L12 or, in some cases, NH-U9 series). Please thus take note of our TDP (Thermal Design Power) recommendatons for smaller cooler models and always consult our extensive compatibility lists and FAQs that provide detailed compatibility information for individual mainboards and other components.

Disclaimer:
We create and update our compatibility lists with the utmost care. Unfortunately, mainboard manufacturers tend to change certain components and heatsinks without pointing it out by using corresponding revision names. If you run into problems while installing our coolers on one of the mainboards listed as being compatible, please don't hesitate to contact our support team at support@noctua.at.

Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues.

For use in systems from Dell, HP or Lenovo, please note this FAQ.

When modern CPUs use their turbo modes, they can (depending on the configuration of the UEFI BIOS) dissipate much more heat than indicated by the manufacturer’s TDP (Thermal Design Power) specification. Just like manual overclocking, this puts higher demands on the cooling solution. Our CPU compatibility list helps you to choose the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned. We classify our coolers according to the following categories:

best turbo/overclocking headroom best turbo/overclocking headroom
medium turbo/overclocking headroom medium turbo/overclocking headroom
low turbo/overclocking headroom low turbo/overclocking headroom
compatible without turbo/overclocking headroom compatible without turbo/overclocking headroom
compatible with certain restrictions (see comment) compatible with certain restrictions (see comment)
incompatible (see comment) incompatible (see comment)

For further information on CPUs exceeding their TDP ratings and how to configure the UEFI BIOS in order to avoid excessively high temperatures, please see this FAQ.

Please also see our general buying guide, motherboard compatibility list and FAQs for further help on how to select the best cooler for your configuration.
