Vienna, April 5th 2022 - Introducing the new NH-D12L & NF-A12x25r PWM fan. At a height of only 145mm (13mm lower than Noctua’s regular 120mm models), the NH-D12L fits many 4U enclosures as well as narrower tower cases that have been previously limited to solutions with 92mm fans. Combined with a level of efficiency that surpasses many full-height 120mm models, the NH-D12L is the perfect choice for applications that require serious cooling performance but cannot fit the larger NH-U12A.
