Advertised Vs. Real Performance
This is probably the most crucial page, showing how accurate the data provided by the manufacturers/brands on their products is. Since nobody so far could verify these numbers, it was an open field for every brand to declare whatever it wanted, but this stops now. I should also note that I strictly follow the specific guidelines (ISO7779: 2018) for taking noise measurements in information technology and telecommunications equipment.
In the table below, anything in red means bad news, while blue is good!
| Advertised Performance | Real Performance | Difference | |
|---|---|---|---|
| Max Speed (RPM) | 2200 | 2153 | -2.14% |
| Max Input Current (A) | 0.30 | 0.37 | +23.33% |
| Max Power (W) | 3.60 | 4.49 | +24.72% |
| Qmax (CFM) | 120 | 110.87 | -7.61% |
| Pmax (mmAq) | 4.00 | 3.41 | -14.75% |
| Max Noise Level (dBA) | 38.3 | 39.7 | +1.4 dBA |
The difference in static pressure is high. The same goes for airflow and power. Only in noise output, the difference is pretty small, but still, the fan is noisy.
