They\u2019re built on an exceptionally efficient aerodynamic design, but come at a lower price point. Using more flexible blades reduces manufacturing costs, and the bearings in the Dynamic 3 fans are also \u201csimpler\u201d compared to the Momentum series. For the user, this doesn\u2019t necessarily mean any major drawback\u2014on the contrary, you can look forward to more pronounced lighting, enabled in part by a larger area of light\u2011conducting material.<\/p>\n

The Dynamic 3 fans share their geometry with the Momentum 12<\/a> (RGB<\/a>) and Momentum 14<\/a> (RGB<\/a>) models, which achieved very attractive results in HWCooling tests. Those results, however, came at a relatively high price\u2014significantly higher than what Dynamic 3 models ask for. The reasons are several, all tied to lower manufacturing costs thanks to cheaper materials used in these fans.<\/p>\n

They likely use a combination of PBT or polycarbonate (instead of LCP used in the Momentum series), depending on the variant. As usual, there are several versions, in both 120 mm and 140 mm formats. In total\u2014if we counted correctly\u2014there are ten variants, six of which (the polycarbonate ones) include ARGB LED lighting. Three variants (likely PBT) come without lighting. Four are labeled \u201cBlack\u201d (Dynamic 3 \u2013 12 Black, etc.) or \u201cWhite,\u201d which we\u2019ll get to shortly.<\/p>\n

One of these variants features a \u201creverse\u201d impeller\u2014blades flipped so that in typical system\u2011cooling positions, the stator struts are hidden from view, resulting in a cleaner and arguably more attractive appearance. This variant (Dynamic 3 \u2013 12 Reverse) exists only in the 120 mm format and is the only one available in a fully white finish. Dynamic 3 fans come in 120 mm (Dynamic 3 \u2013 12) and 140 mm (Dynamic 3 \u2013 14) formats, with most models offering ARGB lighting.<\/p>\n

Each size includes two black\u2011frame and two white\u2011frame models. The black ones are Dynamic 3 \u2013 12 RGB Black, Dynamic 3 \u2013 12 Reverse RGB Black, and Dynamic 3 \u2013 14 RGB Black. The white ones are Dynamic 3 \u2013 12 RGB White, Dynamic 3 \u2013 12 Reverse RGB White, and Dynamic 3 \u2013 14 RGB White. The black RGB fans are also available in three\u2011packs: Dynamic 3 \u2013 12 RGB 3\u2011pack Black and Dynamic 3 \u2013 14 RGB 3\u2011pack Black.<\/p>\n

The smaller 120 mm variants have a listed speed range of 350\u20132200 RPM, while the larger 140 mm models run at 350\u20131800 RPM. This mirrors the Momentum series, except Dynamic 3 uses different bearings\u2014rifle bearings (instead of FDB in Momentum). MTBF is listed the same across all models: under 90,000 hours. For lighting enthusiasts, there\u2019s good news: Dynamic 3 fans will achieve higher brightness. Because the entire impeller conducts light (unlike the ring\u2011based lighting of Momentum RGB), the illuminated surface area is larger.<\/p>\n

As for MSRPs, starting from the lowest: 12 USD for Dynamic 3 \u2013 12 Black<\/a>, Dynamic 3 \u2013 12 Reverse Black<\/a>, and Dynamic 3 \u2013 12 Reverse White<\/a>. Then 14 USD for Dynamic 3 \u2013 14 Black<\/a>. With ARGB lighting, prices rise slightly: 15 USD for the 120 mm models Dynamic 3 \u2013 12<\/a> (Reverse<\/a>) RGB Black, and Dynamic 3 \u2013 12<\/a> (Reverse<\/a>) RGB White. 17 USD for the 140 mm models (Dynamic 3 \u2013 14 RGB Black<\/a> and Dynamic 3 \u2013 14 RGB White<\/a>). Three\u2011packs cost 40 USD (Dynamic 3 \u2013 12 RGB 3\u2011pack Black) and 45 USD (Dynamic 3 \u2013 14 RGB 3\u2011pack Black).<\/p>\n

These Dynamic 3 fans will likely appear sooner or later in some of Fractal Design\u2019s new cases or on the radiators of their AIO liquid coolers. For now, they are sold only individually and are already available in selected stores worldwide.<\/p>\n
