Fan adjustment not working!

hello, i got my noctua 5v fan but when i connect the fan it starts running on full speed and does not adjust the spinning to the temperature, it does not even stop after i click shut down, i need to pull the plug to make it stop.
in need of help.

hello bollen.kenny,

please note that there’s Jetson Nano Supported Component List that provides a list of supported third party components.
also,
there’s PWM controller to manage the fan speeds,
suggest you may review the documentation, please check the Thermal Cooling session for the fan management.
thanks
