Noctua NH-U9DX i4 Xeon CPU Cooler

Award-winning NH-U9/U12DX Series

The NH-U9/U12DX i4 is based on the latest version of Noctua’s award-winning NH-U9/12 coolers. First introduced in 2005, the NH-U series have become a standard choice for premium quality quiet CPU coolers and have won more than 400 awards and recommendations from leading international hardware websites and magazines.

Easier Access to RAM

Thanks to its slim design with only 45mm fin depth, the NH-U12DX i4 ensures easy access to the RAM slots. When installed parallel to the slots, it will not overhang the memory on LGA1356, LGA1366 and LGA2011 Square ILM even with two fans installed, thus providing full compatibility with tall RAM heatsinks.

High quality Noctua Fans

Recommended by more than 150 hardware publications and thousands of enthusiasts world-wide, Noctua’s premium quality NF-F12 Focused Flow 120mm PWM fan supplied with the NH-U12DX is renowned to combine superb static pressure, excellent heatsink performance and surprising quietness of operation. The NH-U9DX is supplied with two NF-B9 92mm PWM Fans in a push-pull configuration and features Noctua’s renowned SSO bearing as well as advanced aerodynamic optimisations such as Bevelled Blade Tips and Vortex-Control Notches in order to achieve its superb quiet cooling capability.

PWM Support and Low-Noise Adaptor

The NF-B9 92mm fans supplied with the NH-U9DX i4 also support PWM for convenient automatic speed control through the motherboard and by using the low-noise adapter, the maximum fan speed can be reduced from 1600 to 1300 rpm.
