Hi, thank you for the quick response. Unfortunately I hadn’t realized your response until now, sorry for that. I ordered the same fan, so could you please be a bit more detailed regarding the cables? That would be great! Because I thought that the three connector cable is only ground, voltage and signal, which lets an actual computer only read out the rpm of the fan.
You mean the two smaller fans inside so that three fans in total connected to the clamp?
Thank you in advance.

Hi, I just received mine an I think I got it now... You mean the low noise adapter cable and the ultra low noise adapter cable, am I right?so you connected the 3-pin cable from the fan to the low noise adapter cable (NA-CR 10), and then to the 3-to-4-pin adapter cable?

Hi, this noctua fan has different connector cables for different speed in three steps. Mine is in the middle. There is a terminal clamp on mainboard for the smaller fan inside. Connect both fans there.

I want to print and test your design for noise reduction obviously... I just wonder how you run the Noctua in low-noise-mode. Did you reduce the voltage with custom firmware or with a resistor? I also found Noctua 3 Pin low-noise-cable. so that's why I am confused. How did you connect the fan to the PSU? A picture would be great.
Thank you in advance!

See answer above, sorry
