    Noctua NF-P12 FAQs



    How to install the fan using the Vibration-Compensators?
    First, pull the Vibration-Compensators through the mounting holes of the case. Then put the fan onto the Vibration-Compensators and pull them through the mounting holes of the fan.

    I've got 2 adapter cables with the cooler. What's the difference between these cables?
    The Low-Noise-Adapter (L.N.A.) and Ultra-Low-Noise-Adapter (U.L.N.A.) reduce the speed of the fan to 1100 / 900 rpm:

    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.

    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.

    Can I disassemble my fan for cleaning?
    In order to ensure flawless operation over many years of usage, all Noctua fans come with a premium grade SSO bearing, which is fully sealed to prevent the entering of fine dust particles. Please 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.

    It is thus recommended to clean your fans 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 don’t use a vacuum cleaner as this may apply excessive force to the fan.

    Can I paint my Noctua fan in order to change its color?
    Since even small variations in the layer of paint can lead to an imbalance of the impeller, resulting in vibrations, higher noise levels, increased stress on the bearing and thus reduced lifespan, we do not recommend painting the fan. Please note that for the reasons stated above, painting the fan will void your warranty.

    What pin configuration do Noctua fans use?
    All Noctua fans feature the standard pin-configurations set out in the Intel and AMD specifications. These standard pin-configurations are used on most mainboards and fan controllers today:

    How can I find out the direction of airflow and sense of rotation?
    When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise:

    How should I clean my Noctua fan?
    Fans inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fans regularly 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.
    In order to ensure flawless operation over many years of usage, Noctua’s premium grade SSO bearings are fully sealed to prevent the entering of fine dust particles. Please 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.

Test verdict: "Mit dem NH-U9S hat Noctua wieder einmal gezeigt, dass man ein gutes Produkt mit viel Entwicklungsarbeit noch besser machen kann. Dies bezieht sich nicht nur auf die Kühlleistung des neuen NH-U9S, sondern auch auf die Kompatibilität." (Patrick Seus, mod-your-case.de)

Test verdict: "After I spent some time having fun with the biggest fans included in the series I can say that I am really impressed to see the classic NF-P14 revived in the shape of two brand new, much cheaper versions with absolutely renewed appearance and much better performance."

26.11.2014 - ZeDen.net NH-D15
Test verdict: "Au final, le bilan de ce ventirad est vraiment très bon. Les améliorations apportées par Noctua à son produit phare, le NH-D14, nous ont vraiment convaincues. Le NH-D15 est bel et bien le meilleur ventirad de la marque, notamment grâce à ses nouveaux ventilateurs et à son design de radiateur revu pour une meilleure comptabilité. Bien sûr, ce niveau de qualité a un prix, mais il ne faut pas oublier que si cette solution haut de gamme - modulaire et adaptables à presque tous les sockets - peut paraitre chère, elle peut rivaliser avec les watercooling AIO les plus récents !"
