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 follow the specific guidelines (ISO7779: 2018) for taking noise measurements in information technology and telecommunications equipment strictly.
In the table below, anything in red means bad news, while the blue fonts are good!
| Advertised Performance | Real Performance | Difference | |
|---|---|---|---|
| Max Speed (RPM) | 2000 | 2048 | +2.40% |
| Max Input Current (A) | 0.20 | 0.17 | -15.00% |
| Max Power (W) | 2.40 | 2.04 | -15.00% |
| Qmax (CFM) | 63.33 | 64.21 | +1.39% |
| Pmax (mmAq) | 2.61 | 2.35 | -9.96% |
| Max Noise Level (dBA) | 33.78 | 36.6 | +2.82 dBA |
The notable difference is in static pressure. In airflow, the fan achieves higher performance than the claimed one.
