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): 2000 / 2048
- Max Input Current (A): 0.20 / 0.19
- Max Power (W): 2.40 / 2.27
- Qmax (CFM): 90.04 / 81.73
- Pmax (mmAq): 2.71 / 2.51
- Max Noise Level (dBA): 35.73 / 38.60
The claimed airflow is 9.23% lower than the claimed performance.
The claimed static pressure is 7.38% lower than the claimed performance.
The actual noise output is 2.87 dBA higher than the claimed.

There are specific guidelines for taking noise measurements in information technology and telecommunications equipment (ISO7779: 2018), which I follow strictly.
Silverstone Vista on p10 chart has to be wrong, especially on the 20db chart
We re-measured all fans. I will look into that.
between these and the phanteks t30s, which would you pick? or is there another high performance, thicker fan you’d go with?
Phanteks most likely because it performs better in the normalized tests.
