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
Performance is low at low fan speeds.
25 dBA Noise Output
Airflow is decent, but static pressure is low.
30 dBA Noise Output
Again, decent airflow, but low static pressure.
35 dBA Noise Output
Airflow and airflow are decent, mostly because of the outstanding performance that the Phanteks fan achieves.
