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 the Blue fonts are good!
| Performance Metric | Advertised Performance | Real Performance | Difference |
|---|---|---|---|
| Max Speed (RPM) | 1600 | 1595 | -0.31% |
| Max Input Current (A) | 0.3 | 0.19 | -36.67% |
| Max Power (W) | 3.6 | 2.26 | -37.22% |
| Qmax (CFM) | 90.5 | 80.1 | -11.49% |
| Pmax (mmAq) | 2.9 | 1.64 | -43.45% |
| Max Noise Level (dBA) | 27.9 | 34.1 | +6.2 dBA |
Real airflow is way lower than the advertised, but what is a true revelation is static pressure, where the real value is close to 44% lower than the claimed one! True noise output is also way higher.
