Hi,
temporarily you could just wire your fan so that it will always work on the max speed instead of taking the fan control commands from the motherboard
Yes it can be switched to max RPM of fan like this:
ruik ruik # echo 1 > /sys/class/hwmon/hwmon1/device/pwm1_enable ruik ruik # echo 255 > /sys/class/hwmon/hwmon1/device/pwm1
Maybe you will have something else than hwmon1
Thanks Rudolf
