It is in manual mode after boot... (but I think there's some fan control going on, weird; I may be imagining it, was not able to trigger it on purpose). root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2_enable 1 root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2 80 root@amd:/sys/class/hwmon/hwmon1/device# echo 0 > pwm2 root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2 80 root@amd:/sys/class/hwmon/hwmon1/device# I even tried to set it to 1, but no luck: root@amd:/sys/class/hwmon/hwmon1/device# echo 1 > pwm2_enable root@amd:/sys/class/hwmon/hwmon1/device# echo 0 > pwm2 root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2 80 root@amd:/sys/class/hwmon/hwmon1/device# echo 2 > pwm2 root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2 80 root@amd:/sys/class/hwmon/hwmon1/device# ...and set it there and back: root@amd:/sys/class/hwmon/hwmon1/device# echo 2 > pwm2_enable root@amd:/sys/class/hwmon/hwmon1/device# echo 1 > pwm2_enable root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2 80 root@amd:/sys/class/hwmon/hwmon1/device# echo 40 > pwm2 root@amd:/sys/class/hwmon/hwmon1/device# cat pwm2 80 root@amd:/sys/class/hwmon/hwmon1/device# Any other ideas?
