Product line:

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 LGA1851/LGA1700/LGA1200/LGA115x 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.



Key features

145mm 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.

100% RAM compatibility on LGA1851/LGA1700 and AM4/AM5

Due to its asymmetric design, the NH-D12L does not overhang the RAM slots on Intel LGA1851 / LGA1700 / 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.

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.

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.
