Normalized Noise Tests
For these tests, I set the fan to speeds with noise output at the following predefined levels: 20/25/30/35/40/45 dBA. I skip the corresponding tests if the fan under the test cannot reach some noise levels. The speeds shown in the graph below are measured with the fan in a clear space inside my hemi-anechoic chamber without any obstacles. I set these speeds on the Longwin machine, but they slightly change because of the variable conditions that the device applies.
20 dBA Noise Output
High airflow and static pressure compared to other 140mm fans.
25 dBA Noise Output
High airflow and static pressure.
30 dBA Noise Output
Good airflow and top static pressure.
35 dBA Noise Output
High airflow and static pressure.
40 dBA Noise Output
Top airflow and static pressure.
