But for the HWCooling editorial team it is “Approved” for now.

If you don’t mind the dronier frequencies, then feel free to assume it got the award. In the main area, cooling efficiency, however, the 120 mm Fluctus is excellent.įor a good while, we considered the “Smart buy!” award, but we’ll save that for next time when the acoustics are fine-tuned. Still, it must be stressed that this is a 12-euro fan, where “mediocrity” in several aspects is somehow expected. Comparably average is the power draw as well and ratios derived from it to airflow, or static pressure per Watt. There is definitely room for improvement. Vibrations from turbulence and the motor have been reduced, but on the whole and compared to the competition, their intensity is average. The average noise level in dBA is admittedly higher with it, as the noise level increases due to the increase in mechanical resistance, but at more pleasant middle frequencies. The only thing that breaks up these frequencies and shifts the dominant noise intensity to 587 Hz is, paradoxically, the hexagonal grid. Rumble frequencies are pronounced even with obstacles, including a nylon dust filter, with which a higher than normal noise level is achieved. Peaks at these frequencies are also visible in the SilentiumPC spectrograph, but their relative noise level is supposed to be significantly lower in relation to the other frequencies and they are supposed to be exceeded by the treble around 2.5 kHz, which is quite strange and that’s why we don’t take this graph too much into account. SilentiumPC could argue that these frequencies are amplified by the design of our tunnel (but even a computer case is inherently a wind tunnel) and, most importantly, none of the other fans we’ve tested so far have performed at these frequencies this way in such a pronounced way. Namely, strong rumbling frequencies in the 130-200 Hz range. But there’s one little thing that can make this whole effort disappointing.

The fact that higher Airflow and Pressure values are achieved in normalized modes based on noise levels than the Sigma Pro PWM 120 confirms the claim that the fan design reduces noise while increasing cooling performance.
However, we can only recommend this all-purpose fan if you are not sensitive to a more “rumbly” sound.Īnd here we get to those psychoacoustic optimizations. In addition to system cooling, this makes it a good low-cost choice for radiators. With decreasing speed, however, the intensity of the overpressure fades significantly less than that of the underpressure (the higher static pressure of the underpressure is practically only at maximum speed). The latter does not usually play an important role in a well-sealed system, and the static pressure of the fans is usually similar, and often the same for underpressure and overpressure. What is remarkable is how the amount of static pressure varies as a function of speed with respect to rotor orientation. In the of static pressure values, the SilentiumPC fan lags a little behind, but it still holds up well. On a thinner radiator, the Fluctus even beats it when it comes to airflow. Mostly, it’s just below the nearly three times more expensive MSI MEG Silent Gale P12. Airflow performance in normalized modes under fixed dBA achieves excellent results across the entire speed spectrum. Relative to its price, the Fluctus is truly a killer of competing models and nipping at the heels of even the significantly more expensive ones. But well, even at this price we can state that it is still a still a cheap option. You can’t buy the Fluctus 120 PWM for under 12 euros and you can get the Sigma Pro PWM 120 for 7 euros. Compared to the Sigma Pro PWM 120, of which the Fluctus is a direct successor, there is a significant difference in price as well. EvaluationĬompared to previous SilentiumPC fans, the Fluctus 120 PWM is a big leap. And while there’s no reason to smirk (psychoacoustics is a legitimate scientific field), there were some imperfections that the Poles didn’t avoid. The company’s marketing, however, talks about psychoacoustic optimizations. But, to beat the whirring Sigma Pro 120 PWM and the obviously sketchy Sigma Pro Corona RGB 120 is relatively simple. SilentiumPC presents the Fluctus 120 PWM as its very best fan.
