hey! I’m currently working on a Pi 5 setup & ran into an issue stated above. before soldering wires together, I wanted to test, making sure everything would run properly. unfortunately upon startup, both Noctua fans do not spin, indicating they are not being recognized by the Pi.
when going into: sudo raspi-config -> performance options, there is no sign of fan settings, further indicating them not being recognized.
in order to connect both Noctua fans to the dedicated header on the board, I purchased a JST SH 4-pin to premium male headers cable used by Qwiic boards (both Pi & Qwiic have identical pinout).
connection I have is as follows (from my understanding the Pi header pinout is flipped, maybe it’s not correct after all!):
Noctua fan end JST SH cable end
black (GND) —————> blue (control/PWM)
yellow (+5V, power) ———-> black (GND)
green (tach, sense) —————> yellow (tach)
blue (PWM) —————-> red (+5V)
I coiled both cables together with their corresponding colors on the Noctua fan end (both fan yellows grouped with JST black and so on) with the exception of green tach, which I left one isolated.
running with Pi 5 8GB, 27W official power supply, 32GB microSSD with Pi OS 64bit.![Image]()
