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) | 1800 | 1873 | +4.06% |
| Max Input Current (A) | 0.38 | 0.2 | -47.37% |
| Max Power (W) | 4.6 | 2.44 | -46.96% |
| Qmax (CFM) | 103.9 | 95.34 | -8.24% |
| Pmax (mmAq) | 2.34 | 2.15 | -8.12% |
| Max Noise Level (dBA) | 29 | 33.6 | +4.6 dBA |
The power consumption is lower than what Lian Li states, which is good. Airflow and static pressure are lower than the claimed performance. Finally, the noise output is higher.
