Seasonic Magflow 120mm Cooling Fan Review – ReCheck!

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%
Qmax (CFM) 63.33 64.21 +1.39%
Pmax (mmAq) 2.61 2.35 -9.96%
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.
