PWM support and Low-Noise Adaptor
The NF-F12 120mm fan supplied with the NH-U12S supports PWM for convenient automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation.
Anti-vibration pads and fan-clips for second NF-F12 (optional)
For users who want to achieve even better performance by adding a second, optional NF-F12 fan to create a push/pull setup, the NH-U12S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.
SecuFirm2™ mounting system
Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. Supporting Intel LGA1851, LGA1700 (since 2022), LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) as well as AMD AM4 and AM5 (since 2019), the SecuFirm2™ mounting included with the NH-U12S is straightforward to install, provides perfect contact pressure and will stand the test of time even under heavy use.
Compatibility with past and future sockets
Complying with the open SecuFirm™ standard, the NH-U12S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets.
