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
25 dBA Noise Output
30 dBA Noise Output
In all normalized noise tests, the XPG fan performs excellently!

Some fans like the Arctic P12 have overvoltage protection. A lot of other fans don’t though.
hello, thanks for sharing your insight and test on fans… I love this fan… the only issue I have is the ball bearing noise… my questions is: is the noise lower on PWN or DC mode? thanks in advance!!
PWM always, at low speeds. At high speeds it doesn’t make a difference.
