Due to its slim design, the NH-U12DX i4 now provides easy access to the memory slots and better compatibility with tall modules. Fitted with the professional SecuFirm2 mounting system and bundled with Noctua's industrial-grade NT-H1 thermal compound, the NH-U12DX i4 forms a complete premium quality package for quietly cooling Xeon based workstations and servers.
Award-winning NH-U12 series
The NH-U12DX i4 is based on the latest version of Noctuas 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.
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.
NF-F12 120mm Focused Flow fan
Recommended by more than 150 hardware publications and thousands of enthusiasts world-wide, the Noctuas 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-U12DX i4 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-U12DX i4 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.
