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%|
|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.
