Noctua NH-U12S CPU Cooler. The NH-U12S is the latest 12cm model of Noctua’s classic U-series single tower CPU coolers, which have received more than 400 awards and recommendations from the international press. The S-version’s 45mm slim shape guarantees 100% compatibility with tall RAM modules and at the same time, its fine-tuned design and the class-leading NF-F12 FocusedFlow™ fanwith PWM support for fully automatic speed control allow it to further improve its predecessor’s renowned quiet cooling performance.

Award-winning NH-U12 series.
The NH-U12S is the latest version of Noctua’s award-winning NH-U12 coolers. First introduced in 2005, the NH-U series has become a standard choice for premium quality quiet CPU coolers and won more than 400 awards and recommendations from leading international hardware websites and magazines.

100% RAM compatibility.
Thanks to its slim design with only 45mm fin depth, the NH-U12S will not overhang the RAM slots even with two fans installed. This gives the user full access to the memory modules on all current CPU sockets and guarantees 100% compatibility with tall heatspreaders or optional memory fans.

Classic 120mm tower size for excellent overall compatibility.
Standing 158mm tall, the NH-U12S is short enough to fit most modern mid- or high-end tower cases. Measuring 125mm wide (including fan and fan clips), the cooler stays clear of the top PCIe slot on standard ATX or Micro-ATX motherboards, ensuring best compatibility with SLI and CrossFire setups.

NF-F12 120mm Focused Flow™ fan.
Recommended by more than 150 hardware publications and thousands of enthusiasts world-wide, the Noctua’s premium quality NF-F12 Focused Flow™ 120mm fan is renowned to combine superb static pressure, excellent heatsink performance and surprising quietness of operation.

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 ease of use. Supporting Intel LGA115x (LGA1150, LGA1155, LGA1156), LGA2011 and AMD (AM3+, AM2+, FM1, FM2), the SecuFirm2™ mounting included with the NH-U12S guarantees perfect contact pressure and maximum convenience on all current sockets.

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.
