Results: Static pressure, efficiency by orientation
SilentiumPC presents the Fluctus 120 PWM as its very best fan. But, to beat the whirring Sigma Pro 120 PWM and the obviously sketchy Sigma Pro Corona RGB 120 is relatively simple. The company’s marketing, however, talks about psychoacoustic optimizations. And while there’s no reason to smirk (psychoacoustics is a legitimate scientific field), there were some imperfections that the Poles didn’t avoid.
Results: Static pressure, efficiency by orientation
Explanatory note: Depending on the impeller orientation, different static pressures may be achieved. Within these graphs we observe the ratio between the “pull” and “push” positions, this gives us a sort of coefficient. If its value is above 1.00, it means that the fan exerts a higher static pressure when pulling. If the value is below 1.00, the opposite is true. Sometimes, however, this ratio is overall balanced.
