Noctua NH-U12DX i4, Premium CPU Cooler for Intel Xeon LGA20xx (Brown)

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 12cm model NH-U12DX i4 comes equipped with Noctua’s award-winning NF-F12 Focused Flow fan with PWM for automatic speed control. 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.
NH-U12 120mm tower design The NH-U12DX i4 is based on the latest version of Noctua's well-known NH-U12 coolers. First introduced in 2005, the NH-U series has become a standard choice for premium quality quiet CPU coolers.
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 ensures 100% compatibility with tall heatspreaders or optional memory fans.
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-U12DX i4 ensures perfect contact pressure and maximum convenience on all sockets.
