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.
- Max Speed (RPM): 3000/ 3022
- Max Input Current (A): 0.36 / 0.428
- Max Power (W): 4.32 / 5.14
- Qmax (CFM): 101 / 105.17
- Pmax (mmAq): 7.11 / 6.37
- Max Noise Level (dBA): 39.7 / 43.6
The claimed airflow is 4.13% higher than the claimed performance.
The claimed static pressure is 10.41% lower than the claimed performance.
The actual noise output is 3.9 dBA higher than the claimed.
- Max Speed (RPM): 2000 / 2029
- Max Input Current (A): 0.13 / 0.155
- Max Power (W): 1.58 / 1.86
- Qmax (CFM): 67 / 68.54
- Pmax (mmAq): 3.30 / 2.80
- Max Noise Level (dBA): 27.3 / 32.1
The claimed airflow is 2.3% higher than the claimed performance.
The claimed static pressure is 15.15% lower than the claimed performance.
The actual noise output is 4.8 dBA higher than the claimed.
- Max Speed (RPM): 1200 / 1230
- Max Input Current (A): 0.05 / 0.06
- Max Power (W): 0.55 / 0.74
- Qmax (CFM): 39.1 / 39.14
- Pmax (mmAq): 1.27/ 1.05
- Max Noise Level (dBA): 11.1 / 16.2
The claimed airflow is 0.1% higher than the claimed performance.
The claimed static pressure is 17.32% lower than the claimed performance.
The actual noise output is 5.1 dBA higher than the claimed.
[NOTE] I follow the specific guidelines (ISO7779: 2018) for taking noise measurements in information technology and telecommunications equipment strictly.
Nice share.. Good jon
