    Description

    Noctua's DX line of coolers has become a default choice in high performance quiet cooling solutions for Intel Xeon CPUs. The latest i4 revision supports LGA2011 (both Square ILM and Narrow ILM), LGA1356 and LGA1366 based Xeon platforms and the 9cm model NH-U9DX i4 comes equipped with two of Noctua’s NF-B9 premium fans with PWM for automatic speed control. Standing 125mm tall, the NH-U9DX i4 combines outstanding quiet cooling efficiency with full 4U compatibility. Fitted with the professional SecuFirm2 mounting system and bundled with Noctua's industrial-grade NT-H1 thermal compound, the NH-U9DX i4 forms a complete premium quality package for quietly cooling Xeon based workstations and servers.
    NH-U series
    The NH-U9DX i4 is based on the latest version of Noctua's NH-U9 coolers. First introduced in 2005, the NH-U series has become a standard choice for premium quality quiet CPU coolers.
    4U Compatibility
    Sporting four heatpipes, a surface area of more than 3800cm\xb2 and two premium grade 92mm fans, the NH-U9DX i4 provides a significant upgrade in quiet cooling performance compared to common 2U solutions. At the same time, its 125mm height makes it fully compatible with standard 4U cases.
    SecuFirm2 mounting system
    Noctua's SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel's LGA2011 (both Square and Narrow ILM), LGA2066, LGA1356 and LGA1366 Xeon platforms, the SecuFirm2 mounting included with the NH-U9DX i4 ensures perfect contact pressure and maximum convenience on all sockets.
    2x NF-B9 92mm Premium Fan
    The NF-B9 92mm premium fan 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, the NH-U9DX i4 comes equipped with two NF-B9 fans in a push/pull setup.
