I can start the fan using the
sudo sh -c 'echo 255 > /sys/devices/pwm-fan/target_pwm'
command, however the fan kind of just stutters and then in order to get the fan spinning I have to give it a little push with my finger. Does anyone else have this issue?
I am using the micro usb power supply that Nvidia recommends and the Noctua 40x40x20mm fan they recommend as well.
