I created this page in order to visualize techpowerups highly interesting fan-measurement data in a better way, since their visualization is not particularly intuitive or easy to read in my opinion. All data has been taken from their latest fan review (and some previous ones). Currently the latest included review is of the be quiet! Silent Wings Pro 4 (last update: 15.12.2022). I did not measure this data myself, own no rights to it and can not guarantee that it has been measured or transferred to my system correctly. Please double-check with their datasets if something feels off and let me know if I made any mistake! The lines between datapoints are only extrapolated for better readability and do NOT necessarily represent the actual noise to performance curve. The chart is being drawn by a javascript-version of plotly - a great tool and completely open source and free. Check it out!
