Air volume and pressure are not enough; so nextwe will check the concentration of the fans and
airflow direction. Different fansblades use different designs, so that the flow of air will differ,
that is tosay, emphasis in the heat fans is different.
We put fans in the stationary platform,observeairflow directionto determine the concentration of the
fans. To make the resultscomparable, all fans are set at 1000rpm.
It should be noted that the concentrationof air flow shouldn’t be consider as a standard whether
a fans is high quality.Some users prefer to let the air flow through larger space,meanwhile
othersneed the air go deeper. In this test we will only give a brief analysis of thetest results.
Corsair SP120 airflow direction
Enermax TwisterPressure airflow direction
Noctua NF-P12 airflow direction
PCCooler F1211 IceWind airflow direction
Phanteks PH-F120MP airflow direction
Scythe Slip Stream 120DB airflow direction
SilverStone SST-FQ122 airflow direction
Thermaltake riing airflow direction
As we can see, the Enermax, Noctua, PCCoolerand Scythe fans air volume are more concentrate,
they are designed for highefficiency cooling; the Corsair, Lepa, NB, Phanteks, SilverStone and
Thermaltakefans air volume are slightly divergent, they are suitable for bigger environment.
