FD Dynamic 3: Efficient design (from Momentums) cheaper

They’re 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 “simpler” compared to the Momentum series. For the user, this doesn’t necessarily mean any major drawback—on the contrary, you can look forward to more pronounced lighting, enabled in part by a larger area of light‑conducting material.

The Dynamic 3 fans share their geometry with the Momentum 12 (RGB) and Momentum 14 (RGB) models, which achieved very attractive results in HWCooling tests. Those results, however, came at a relatively high price—significantly 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.

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—if we counted correctly—there are ten variants, six of which (the polycarbonate ones) include ARGB LED lighting. Three variants (likely PBT) come without lighting. Four are labeled “Black” (Dynamic 3 – 12 Black, etc.) or “White,” which we’ll get to shortly.

One of these variants features a “reverse” impeller—blades flipped so that in typical system‑cooling positions, the stator struts are hidden from view, resulting in a cleaner and arguably more attractive appearance. This variant (Dynamic 3 – 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 – 12) and 140 mm (Dynamic 3 – 14) formats, with most models offering ARGB lighting.

Each size includes two black‑frame and two white‑frame models. The black ones are Dynamic 3 – 12 RGB Black, Dynamic 3 – 12 Reverse RGB Black, and Dynamic 3 – 14 RGB Black. The white ones are Dynamic 3 – 12 RGB White, Dynamic 3 – 12 Reverse RGB White, and Dynamic 3 – 14 RGB White. The black RGB fans are also available in three‑packs: Dynamic 3 – 12 RGB 3‑pack Black and Dynamic 3 – 14 RGB 3‑pack Black.

The smaller 120 mm variants have a listed speed range of 350–2200 RPM, while the larger 140 mm models run at 350–1800 RPM. This mirrors the Momentum series, except Dynamic 3 uses different bearings—rifle bearings (instead of FDB in Momentum). MTBF is listed the same across all models: under 90,000 hours. For lighting enthusiasts, there’s good news: Dynamic 3 fans will achieve higher brightness. Because the entire impeller conducts light (unlike the ring‑based lighting of Momentum RGB), the illuminated surface area is larger.

As for MSRPs, starting from the lowest: 12 USD for Dynamic 3 – 12 Black, Dynamic 3 – 12 Reverse Black, and Dynamic 3 – 12 Reverse White. Then 14 USD for Dynamic 3 – 14 Black. With ARGB lighting, prices rise slightly: 15 USD for the 120 mm models Dynamic 3 – 12 (Reverse) RGB Black, and Dynamic 3 – 12 (Reverse) RGB White. 17 USD for the 140 mm models (Dynamic 3 – 14 RGB Black and Dynamic 3 – 14 RGB White). Three‑packs cost 40 USD (Dynamic 3 – 12 RGB 3‑pack Black) and 45 USD (Dynamic 3 – 14 RGB 3‑pack Black).

These Dynamic 3 fans will likely appear sooner or later in some of Fractal Design’s 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.
