From the models still sold under the SilentiumPC brand, the Corona fans have come a long way. They are still more “showy” than “efficient,” although even in their primary function they don’t fall behind as much as you might expect (even if airflow per unit of noise is lower…). Their loyalty to the ring‑style light guide remains. Together with ARGB LEDs, it frames the fan’s impeller—and it really does look good. What do you think?
Results: motor-to-LED consumption ratio
Explanatory note: Lighting components significantly impact fan power consumption. These charts show the ratio between motor power consumption and LED power consumption across standard operating modes (from 31 dBA up to maximum RPM). LEDs are consistently set to maximum brightness. Lower ratio values mean lighting comprises a larger portion of the total power. This is not inherently negative–higher LED intensity can be advantageous and is typically adjustable. Details about LED control options are provided in the previous chapter.
Why is a value sometimes missing for a fan? There can be several reasons. Most commonly, it’s because the fan couldn’t be regulated to the target noise level. Some fans have higher minimum RPM (or they spin slowly but have an excessively noisy motor), or they are simply slower models that can’t reach higher decibel thresholds. Results are also omitted from graphs if the impeller scrapes against the mesh of a nylon filter. In such cases, we classify the combination as incompatible. And of course, a zero in the graphs naturally appears in situations where we record an actual 0.00. This often occurs at extremely low speeds when obstacles are present or during vibration measurements.
