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
- Top static pressure
- Normal power consumption
25 dBA Noise Output
- Average speed
- Low airflow
- Top static pressure
- Increased power consumption
30 dBA Noise Output
- Average speed
- Low airflow
- Top static pressure
- Average power consumption
35 dBA Noise Output
- High speed
- Average airflow
- Top static pressure
- Low power consumption
40 dBA Noise Output
- High speed
- Average airflow
- Top static pressure
- High power consumption
45 dBA Noise Output
- High speed
- Average (to low) airflow
- Top static pressure
- High power consumption

Hi @crmaris can you please tell me what size screws I would need to mount this fan on an AIO radiator?
It is 38mm thick so 45mm long I would say.
Besides the thickness, is there any reason the home enthusiast should not consider these the best watercooling radiator fans for low noise? Less optimal noise frequencies than its competitors?
The thickness is the major issue for most cases, with limited internal space.
That mechanical clicking in the low speed recording sounds like it could get *pretty* irritating.
