    Noctua NH-U12 FAQs



    Is the high weight dangerous for the CPU or socket?
    No. Noctua coolers possess an extremely reliable SecuFirm™ mounting system. Even transporting the pc with the cooler installed is entirely safe. 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.

    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).

    How much space is required around the CPU socket?
    The following illustration shows you exactly how much space is required around the socket:

    The cooling fins of the NH-U12 are put high enough to evade problems with mainboard capacitors and other parts:

    How much space between mainboard and power supply is required when the NH-U12 is installed upright?
    When installed upright (see picture below), the NH-U12 may jut out over the upper edge of the mainboard. In this case, the gap required between the upper edge of the mainboard and the power supply in the case is (depending on the position of the CPU socket on the mainboard) up to 25mm. Measured from the upper mounting holes of the CPU socket, the required distance to the power supply unit is 35mm.

    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:

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

    Which Noctua coolers are compatible with LGA1150?
    The mounting is identical on all LGA115x sockets (LGA1150, LGA1155, LGA1156). The following coolers are thus compatible with LGA1150 out of the box and donít require any upgrades in order to be used on this platform: NH-C12P SE14, NH-C14, NH-D15, NH-D14, NH-L12, NH-L9i, NH-U14S, NH-U12S, NH-U12P SE2, NH-U9B SE2. In addition, all older models which have been upgraded with the NM-I3 kit can also be used on LGA1150 without any further upgrades.

    The following coolers can be made compatible to LGA1150 using the NM-i115x Upgrade-Kit and are eligible for Noctuaís free mounting kit offer: NH-C12P, NH-U12, NH-U12F, NH-U12P, NH-U12P SE1366, NH-U9, NH-U9F, NH-U9B.

    The following coolers can be made compatible to LGA1150 using the NM-i115x Upgrade-Kit but are not eligible for Noctuaís free mounting kit offer: DX-Series Xeon coolers, NH-D14 SE2011.

    The following coolers are mechanically incompatible with the NM-i115x Upgrade-Kit and can not be made compatible with LGA1150: DO-Series AMD Opteron coolers, NH-L9a.

    Which sockets are supported or can be supported using upgrade kits?
    Please refer to our socket compatibility chart.

Test verdict: "I was really surprised that the Noctua could keep such a low temperature, but I ran the test three times and reapplied TIM every time looking for what I did wrong, but I couldn't find anything odd. As for the load temperatures, all I can say is I have a huge smile on my face still." (Ambrosidou Nat, XtremeSystems.org)
