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.
It’s been a while since I had a fan that can go up to 35 dBA, meaning I have to test four different levels.
20 dBA Noise Output
25 dBA Noise Output
30 dBA Noise Output
35 dBA Noise Output
40 dBA Noise Output
45 dBA Noise Output

between these and the phanteks t30s, which would you pick? or is there another high performance, thicker fan you’d go with?
Phanteks most likely because it performs better in the normalized tests.
Silverstone Vista on p10 chart has to be wrong, especially on the 20db chart
We re-measured all fans. I will look into that.
