    Noctua NF-S12-1200 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.

    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.

28.11.2014 - mod-your-case.de NH-D9L
Verdict du test: "Mit dem NH-D9L geht Noctua einen etwas anderen Weg als bei dem kürzlich getesteten NH-U9S und kreiert einen sehr kleinen Twin-Tower-Kühler, welcher in der Theorie mit bis zu drei Lüftern bestückt werden kann. Durch diesen Aufbau ist Noctua ein sehr guter Spagat zwischen einer guten Kühlleistung und einer sehr hohen Kompatibilität gelungen. Die Kühlleistung liegt trotz der im Vergleich zum NH-U9S geringeren Masse und dem mittig montierten Lüfter auf einem sehr guten Niveau." (Patrick Seus, mod-your-case.de)

27.11.2014 - mod-your-case.de NH-U9S
Verdict du test: "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)

Verdict du test: "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."
