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
- Low speed
- Low airflow
- Average static pressure
- Average to low power consumption
25 dBA Noise Output
- Low speed
- Low airflow
- Average static pressure
- Average to low power consumption
30 dBA Noise Output
- Low speed
- Low airflow
- High enough static pressure
- Average power consumption
35 dBA Noise Output
- Low speed
- Low airflow
- High enough static pressure
- Increased power consumption

Thank you for another great review! Do you have any plans of testing smaller fans? I have a HTPC using a Silverstone GD09 case and it uses 2 80mm fans for exhaust. I’m trying to pick the best fan but as you have shown I can’t just go of the specs listed on the box. Thanks again and take care.
We plan at some point to do more fans in general, yes.
