It’s not a joke. It may sound silly, but know that we are not presenting you with anti-physics. On the contrary, the foundation in physics here is very good. Different colors of materials, as long as they are not just a surface finish but a homogeneous mass, can (and often do) affect their strength. Our sensitive measurements reveal well the differences that exist between the white and black variants.
Results: Vibration, in total (3D vector length)
Explanatory note: We have already described how to measure the vibration intensity in the corresponding chapter within the testing methodology. However, it is worth emphasizing here what we mean by “cumulative vibration”. In order to be able to interpret the motion in the three axes (X, Y, Z) as simply as possible, with a single number, we consider the individual axes as vectors and calculate the so-called 3D vector from them. A more detailed account at the level of the individual axes is given in the next three chapters of this article.
Prečo niekedy pri ventilátore chýba hodnota? Dôvodov môže byť viac. Obvykle je to preto, že nebolo možné daný ventilátor zregulovať na cieľovú hladinu hluku. Niektoré majú vyššie minimálne otáčky (alebo otáčky sú aj nízke, ale má príliš hlučný motorček) alebo sa jedná o pomalší ventilátor, ktorý si na vyššie decibely nedosiahne. Výsledky v grafoch chýbajú ale aj vtedy, ak sa rotor šúcha o sito nylonového filtra. Vtedy túto kombináciu vyhodnocujeme ako nekompatibilnú. A nula v grafoch je prirodzene aj v situáciách, kedy nameriame 0,00. To je častý jav pri mimoriadne nízkych otáčkach s prekážkami alebo v rámci meraní vibrácií.
Hey, when are you going to Review the Noctua NF-A12x25 Brown and Chromax version? I’d love to see if it has the same issue as the Corsair AF120 and also see it’s general Performance. Also please Review the Phanteks T30 too, i would love to see how it compares to the Noctua.
Billy, welcome. Thank you for your question. We have all these tests planned, including the comparison of brown and black Noctua NF-A12x25. In order to make these tests viable, we have to build them in some reasonable way, it can’t be all at once (although I understand that would be the most attractive for the readers). It’s a project for several years and we will get to everything sooner or later. But the NF-A12x25 PWM (brown) tests are really close. 🙂
