DeepCool FC120: Big ARGB blades in a “small” cross-section

Results: Vibration, in total (3D vector length)

The biggest advantage, but at the same time the biggest disadvantage of the DeepCool FC120 fan are its long and overall large blades, whose area exceeds that of competing models. Among illuminated fans, this one represents one of the most efficient solutions with ARGB LEDs, in optimal conditions. However, it is important to notice its downsides, which are a side effect of the chosen rotor design.

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.







Why is there a missing value sometimes? There may be more reasons. Usually it is because the fan could not be adjusted to the target noise level. Some have a higher minimum speed (or the speed is low, but the motor is too noisy) or it is a slower fan that will not reach the higher decibels. But the results in the graphs are also missing if the rotor is brushing against the nylon filter mesh. In that case, we evaluate this combination as incompatible. And zero in the graphs is naturally also in situations where we measure 0.00. This is a common occurrence at extremely low speeds with obstructions or within vibration measurements.
