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!
| Advertised Performance | Real Performance | Difference | |
|---|---|---|---|
| Max Speed (RPM) | 2500 | 2370 | -5.20% |
| Max Input Current (A) | 0.25 | 0.23 | -8.00% |
| Max Power (W) | 3.0 | 2.71 | -9.67% |
| Qmax (CFM) | 77 | 73.86 | -4.08% |
| Pmax (mmAq) | 2.7 | 3.04 | +12.59% |
| Max Noise Level (dBA) | 36.0 | 39.0 | +3.0 dBA |
The claimed airflow is lower, not by a large margin, while the true static pressure is notably higher than the advertised!
