If you’re looking for illuminated fans without compromises that also deliver high cooling efficiency, the FD Momentum 12 RGB may be the right choice. These fans strike an excellent balance between visual appeal and performance. Their efficient geometry and exceptionally rigid blades are complemented by circular lighting. The Momentum 12 RGB fans are so far the only illuminated fans we’ve given the “Top-notch” award.
Results: Static pressure, efficiency depending on orientation
Explanatory note: The orientation of the impeller can affect the resulting static pressure. In these graphs, we examine the ratio between the “pull” and “push” configurations, effectively producing a coefficient. A value greater than 1.00 indicates that the fan produces higher static pressure when pulling. Conversely, a value below 1.00 means it performs better when pushing. In some cases, the ratio is balanced and close to unity.
The RGB variant, despite having a smaller rotor size to work with, outperforms the black variant the vast majority of the time. I suspect the RGB variant was designed first, which is then stretched outwards to form the black variant’s motor… If the 14 cm variants are designed the same way I suspect we’ll see relatively worse results.
Anyway, excellent job from Fractal.
In terms of unobstructed flow, they are similar, but with increasing resistance, the flow of the RGB variant increases. Ľubo and I thought, that the paradoxically shorter blades, which probably lead to higher RPM, probably contribute the most to this behavior. And secondarily, perhaps the less conical inner frame 🙂
