returns:
lm63-i2c-0-4c Adapter: i2c-mt65xx fan1: 2166 RPM (min = 0 RPM) temp1: +54.0°C (high = +70.0°C) temp2: +53.2°C (low = +0.0°C, high = +70.0°C) (crit = +125.0°C, hyst = +115.0°C)
Change Fan Speed
SSH in.
cd /sys/class/hwmon/hwmon0 echo 70 > pwm1
NOTE: This controls a PWM fan – the industry standard – with software.
- But it may reset on its own after an hour or so.
Check Fan Speed Configuration
cat /sys/class/hwmon/hwmon0/pwm1_enable
returns
1
NOTE: According to the hwmon docs at kernel.org, this means that the fan is configured for fixed-speed operation.
- The following should enable automatic fan speed control in theory:
echo 2 > /sys/class/hwmon/hwmon0/pwm1_enable
- Check the contents of sys/class/hwmon/hwmon0/pwm1_auto_point_* to see a list of temperature settings.
