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 in front of them. I set these speeds on the Longwin machine, but they slightly change because of the variable conditions that the machine applies.
20 dBA Noise Output
25 dBA Noise Output
30 dBA Noise Output
In all normalized noise tests, the EK fan doesn’t shine.
