If you compare the absolute values with those of many other fans, you will hear a bit more of the operating noise especially from thicker radiators. However, the fan then also performs worse. Pressure creates counterpressure, also at the ears. Humming is almost nonexistent, though, so that’s good.
We have attached all fans already tested with the more detailed method in the gallery for a better comparison. The Seasonic MagFlow is the first fan in the gallery, followed by the rest.
Sound comparison (recording) at all speeds
As just mentioned, the subjective feeling is a somewhat clearer noise from the motor and the rotor blades, which is of course also due to the different speeds. The fan produces significantly more motor noise, and the tearing noise at the rotor blade edges is also audible.

25 mm radiator
45 mm radiator
60 mm radiator
If the speakers have survived the whole thing up to this point, we’ll now go into more detail.
Frequency spectrum
Let’s look at the frequency analyses of all measurements and all tested speeds. The graphs speak for themselves, as there are hardly any disturbing peaks that lie outside the expected speed ranges for bearings and rotor blades.
