Although color can influence performance characteristics (as observed, for example, <a href=\"https:\/\/www.hwcooling.net\/en\/when-color-matters-corsair-af120-elite-weaker-in-white\/\">in our comparisons between white and black Corsair AF120 Elite fans<\/a>), Noctua\u2019s position is that with its tuned LCP material (or \u201cSterrox\u201d), the goal is achieving equivalent results.<\/p>\n<p>Before the first-generation NF-A12x25 fans arrived in black, it took more than <a href=\"https:\/\/www.hwcooling.net\/cierny-den-noctuy-vysli-nf-a12x25-a-nh-u12a-chromax-black\/\">three years from the launch of the brown-and-beige versions<\/a>. This time, that interval has been shortened to roughly one year, partly because the material itself (black Sterrox\/LCP) is already functional and proven for practical deployment in a form Noctua considers acceptable. Recoloring a fan is not a trivial process when the goal is preserving original mechanical characteristics, particularly high rigidity. That, however, is exactly what Noctua promises, and until test samples become available, we\u2019ll have to wait to challenge those claims.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"noborder alignnone wp-image-277613\" src=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01-1024x1024.jpg\" alt=\"\" width=\"870\" height=\"870\" srcset=\"https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01-1024x1024.jpg 1024w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01-300x300.jpg 300w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01-768x768.jpg 768w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01-1536x1536.jpg 1536w, https:\/\/www.hwcooling.net\/wp-content\/uploads\/2026\/05\/noctua-nf-a12x25-g2-chromax.black-01-2048x2048.jpg 2048w\" sizes=\"auto, (max-width: 870px) 100vw, 870px\" \/><\/a><\/p>\n<p>The specifications are already known\u2014the impeller geometry uses \u201cProgressive bend,\u201d characterized for example by its distinctive \u201chumpbacked\u201d blades. The purpose of this design lies primarily in higher efficiency toward the center of the impeller, near the hub. Efficiency naturally declines in these areas, and this modification is intended to improve yield across the blade\u2019s full length. In addition to older micro-optimizations (<a href=\"https:\/\/www.noctua.at\/en\/expertise\/tech\/flow-acceleration-channels\">FAC<\/a>, <a href=\"https:\/\/www.noctua.at\/en\/expertise\/tech\/inner-surface-microstructures\">ISM<\/a>, and <a href=\"https:\/\/www.noctua.at\/en\/expertise\/tech\/stepped-inlet-design\">SID<\/a>), there is also the \u201ccentrifugal turbulator,\u201d or segmented hub surface, which is designed to distribute airflow streams more effectively ahead of the blades\u2019 leading edges.
