![]() The frame has the same, slightly grained surface. But it is at least lightly roughened by “sandblasting”, so the air streams don’t tend to slide down the length of the blades as they do on mirror-smooth surfaces, which is good. The surface of the blades is simple, without cut-outs, protrusions or any articulation. They are not as tight as in the BeQuiet! Silent (Pro) Wings 4, but here the leading edges are almost in the axis of the trailing edge of the previous blade as well. The motor housing is slightly smaller than most competing fans with similar rotor types, and the perpendicular gaps between the blades are also relatively smaller. The blades have a relatively large surface area. That is, unless an unattached cable or some other object gets caught between the blades. In practice, of course, it doesn’t matter that much, because there are no forces that would damage the fan in any way. AF120 Elite blades break at a relatively small bend. The bigger difference (compared to sterrox) is in the durability of the material, which Corsair has significantly lower. It may not be quite as good as the “sterrox” LCP from Noctua, but the difference in strength is relatively small. Its elasticity is low even when force is applied to the blade tip, where the elasticity is naturally greatest. The rotor is made of an unspecified material, which, however, is characterised by its very high strength. However, Corsair is well aware of how important compressive strength and low thermal expansivity of the material used is for this type of rotor. From lower static pressure, to the generation of resonant frequencies, to the transmission of vibrations to the frame that contribute to secondary noise (e.g. This design also brings with it some pitfalls and manufacturers have to tackle in particular with the blades not being too flexible.Īt these proportions with less width and more length, they often are and there are often a number of negative side-effects. ![]() This is for greater concentration of air currents in the desired (more straightforward) direction. Like everyone, Corsair is ditching traditional rotors and going the route of more blades with a more pronounced curvature with the the latest AF120 Elite fans. Someone who knows what they’re doing was behind its design, because they did a hell of a job. And that’s the magic of the AF120 Elite fan. Not that we approach Corsair’s elite fan with any preconceived notions, but for an absolutely top-notch fan, its design seems a bit simple. ![]() You know, the less you expect from something, the bigger the surprise can be in the end. ![]()
