Noctua NH-D12L Low Height Dual Tower CPU Cooler NH-D12L

[features] The NH-D12L is a low-height 120mm class CPU cooler that has been conceived to combine outstanding quiet cooling performance with superior case compatibility. At a height of only 145mm (13mm lower than Noctua’s regular 120mm models); it fits many 4U enclosures as well as narrower tower cases that have been previously limited to solutions with 92mm fans. At the same time; its five heatpipe dual-tower design and state-of-the-art NF-A12x25r 120mm fan allow it to achieve a level of efficiency that surpasses many full-height 120mm models. Thanks to its single-fan configuration and asymmetrical fin stacks; the NH-D12L provides 100% RAM compatibility on AMD AM4/AM5 and LGA1700/1200 by staying clear of the memory slots. Topped off with the renowned SecuFirm2 mounting system; Noctua’s award-winning NT-H1 thermal compound and a 6-year manufacturer’s warranty; the NH-D12L is the perfect choice for applications that require serious cooling performance but cannot fit the larger NH-U12A.5mm height for broader case compatibility While Noctua’s regular 120mm CPU coolers stand 158mm tall; the NH-D12L measures only 145mm. This allows it to fit not only a wide range of 4U rackmount server cases and many tower-style enclosures that are not wide enough for 158mm units; but also some larger Small Form Factor (SFF) and Mini-ITX chassis. More performance at lower height Despite its reduced height; the NH-D12L easily outperforms 92mm coolers. It can even surpass renowned 120mm units such as the NH-U12S and often comes close to Noctua’s award-winning 120mm flagship model NH-U12A. Round-frame NF-A12x25r PWM fan Introduced in 2018; Noctua’s NF-A12x25 is widely considered to be the best 120mm fan on the market. The round-frame variant used on the NH-D12L provides the same renowned quiet cooling performance yet makes it possible to reduce overall cooler height without risking compatibility issues with tall motherboard heatsinks or shrouds. 100% RAM compatibility on LGA1700/1200 and AM4/AM5 Due to its asymmetric design; the NH-D12L does not overhang the RAM slots on Intel LGA1700 (LGA17xx family)/LGA1200/LGA115x and AMD AM4/AM5 based motherboards; which ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders or RGB lighting. On LGA2066; the rear fin stack will overhang the RAM slots on the left-hand side of the socket; so RAM modules must not exceed 45mm height. PWM support and Low-Noise Adaptors The NF-A12x25r 120mm fan supplied with the NH-D12L supports PWM for convenient automatic speed control through the motherboard: full performance under load; virtually silent at idle! In addition; the maximum fan speed can be reduced from 2000 to 1700rpm using the supplied Low-Noise Adaptor for even quieter operation. Dual-fan options The NH-D12L ships with a second pair of fan clips that can be used to install a second NF-A12x25r PWM fan either on the front or on the rear fin stack. However; it must be noted that the second fan will usually sit on top of either the RAM or I/O panel and thereby increase the total height beyond 145mm. SecuFirm2 multi-socket mounting system Noctua’s SecuFirm2 mounting systems have become synonymous with quality; safety and easy installation. Supporting Intel LGA1700 (LGA17xx family); LGA1200; LGA115x (LGA1150; LGA1151; LGA1155; LGA1156) and LGA20xx (LGA2066; LGA2011-0; LGA2011-3); as well as AMD AM4 and AM5; the SecuFirm2 mounting included with the NH-D12L is straightforward to install; provides perfect contact pressure and will stand the test of time even under heavy use. Compatibility with past and future sockets Thanks to Noctua’s SecuFirm ecosystem; the NH-D12L can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit; which is provided free of charge. If technically possible; Noctua will also provide upgrade kits for future sockets; which makes the NH-D12L a safe long-term investment. NT-H1 thermal compound Noctua's much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance; excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide; it has established itself as a benchmark for premium-quality thermal compounds. Soldered interface between heatpipes and fins With many heatsinks; the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium; this fit can loosen over years of thermal cycling; which may lead to reduced performance. By contrast; the NH-D12L’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage. 6-year manufacturer’s warranty Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy; the NH-D12L heatsink is built to last; and like all Noctua fans; the supplied NF-A12x25r features an MTTF rating of more than 150;000 hours. The entire package comes with a full 6-year manufacturer’s warranty.
