A 12 cm model, the NH-U12S DX-3647 is a powerful single-tower CPU cooler in Noctua's classic U-Series, which has received more than 400 awards and recommendations from international trade publications. The larger format, six heatpipes and two NF-A15 120mm fans with PWM support for fully automatic cruise control, the silent cooling performance of the NH-U12S DX-3647 surpasses all other U-Series coolers.

At the same time, the 45 mm slim design guarantees high compatibility with bulky memory modules. The all-round high-quality package is completed by the proven SecuFirm2 mounting system, Noctua's renowned NT-H1 thermal compound and a 6-year manufacturer's warranty. Its outstanding cooling performance, good compatibility and excellent running smoothness make the NH-U12S DX-3647 a premium solution for the highest demands.

Premium fan ensures best cooling
With a height of 158 mm, the NH-U12S DX-3647 fits easily into most modern high-end tower enclosures. With a width of 97mm (including fan and fan brackets), the cooler offers better compatibility with SLI and CrossFire systems than models that are over 150mm wide or use wider fans.

The NF-A12x25 is a quiet 120mm premium round AAO (Advanced Acoustic Optimization) fan with advanced aerodynamic design features such as Flow Acceleration Channels for improved performance over the award-winning NF-P12. It supports PWM for convenient, fully automatic cruise control via the motherboard.

More power in the pull / push process
The cooling efficiency is increased by the use of two NF-A12x25 fans in push / pull operation. The NH-U12S DX-3647 comes with special fan clips and a set of anti-vibration pads. These make it possible to set the rear fan by 5 mm and thus achieve better acoustics in double fan operation.

Noctua's SecuFirm2 mounting systems have become synonymous with quality, reliability and ease of use. The NH-U12S DX-3647 is a dedicated version for Intel's LGA3647 sockets in square and narrow design with Xeon CPUs, which is particularly easy to assemble. Simply put the cooler on, tighten the four spring screws and you're done! In addition, due to an enlarged and customized contact surface, this cooler can not be used on other sockets and is not compatible with Noctua's standard mounting system.
