NF-F12 PWM
What is not on the chart is the amount of clicking. It’s missing because all the fans had the same amount of clicking at all speeds: none. That’s amazing. Mission One accomplished.
Note that the percent PWM duty applied to the fans is approximate. But within the ability to test the RPM and the PWM duty percentage, the speeds of these fans scaled more or less linearly with the PWM duty.
As usual for Noctua fans, these were quiet. Even the F12, was quiet and it was spinning at 1470 rpm (some of the SPL results could have been quieter than measured; twelve dBA is the lower limit of the equipment and the environment).
"I did observe that the air normally spilling out the sides of the fin stacks of the D14 (and demonstrate with a tissue) was absent when the F12 was mounted there. It appears that the F12’s airflow truly is focused, as advertised. [...] the NF-F12 PWM is a fine fan in its own right." (Edward Hume, overclock.net)
