Powerful dual-tower CPU cooler for AM5 and LGA1700 sockets. Compatible with AM4, AM5, LGA 1150, LGA 1151, LGA 1155, LGA 1156, LGA 1200, LGA 1700, and LGA 1851 processor sockets. Cooling type: Active (with fan). Dimensions (HxWxD): 145 mm x 125 mm x 112 mm. Maximum fan speed: 2000 rpm. Maximum airflow: 102.1 m³/h. Operating noise level: 22.6 dBA. The NH-D12L chromax.black is a completely black version of Noctua's award-winning NH-D12L low-profile cooler in the 120 mm class, known for its excellent cooling performance and high case compatibility. With a height of just 145 mm (13 mm shorter than classic 120 mm Noctua models), it fits into numerous 4U systems as well as narrower tower cases that were previously limited to solutions with 92 mm fans. Thanks to its dual-tower design with five heat pipes and the groundbreaking 120 mm fan NF-A12 x 25r, it achieves a performance level that surpasses many full-height 120 mm models. The single-fan configuration and asymmetric design ensure that the NH-D12L does not extend over the memory slots on AMD AM5/AM4 and Intel LGA1851/1700/1200, providing 100% RAM compatibility. The high-quality overall package is completed by the proven SecuFirm2 mounting system, Noctua's renowned NT-H1 thermal paste, and a 6-year manufacturer's warranty. Overall, the NH-D12L is the perfect choice when top-notch cooling performance is needed but there is not enough space for the larger NH-U12A.
