Advertised Vs. Real Performance
This is probably the most crucial page, showing how accurate is the data provided by the manufacturers/brands on their products. 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.
Advertised Vs. Real Performance:
- Max Speed (RPM): 2000/ 2015
- Max Input Current (A): 0.19 / 0.20
- Max Power (W): 2.28 / 2.36
- Qmax (CFM): 70.8 / 65.08
- Pmax (mmAq): 3.19 / 2.60
- Max Noise Level (dBA): 22.6 / 30.7
The claimed airflow is 8.08% lower than the claimed performance. The claimed static pressure is far from the true one, with an 18.50% difference. The same goes for the maximum noise output (claimed vs. what I measured), where the difference is vast at 35.8%.
There are specific guidelines for taking noise measurements in information technology and telecommunications equipment (ISO7779: 2018), which I follow strictly.
