我正在尝试控制我的 ubuntu 服务器的风扇速度。它有一个 Asrock 970 extreme4 和一个 AMD 8350。
我安装了 fancontrol 等，但是当我运行 pwmconfig 时它输出：
Found the following devices:
hwmon0 is nct6776
hwmon1 is fam15h_power
hwmon2 is k10temp
Found the following PWM controls:
hwmon0/pwm1 current value: 255
hwmon0/pwm2 current value: 255
hwmon0/pwm3 current value: 255
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon0/fan1_input current speed: 0 ... skipping!
hwmon0/fan2_input current speed: 0 ... skipping!
hwmon0/fan3_input current speed: 0 ... skipping!
hwmon0/fan4_input current speed: 0 ... skipping!
hwmon0/fan5_input current speed: 0 ... skipping!
There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.
这意味着我没有得到风扇控制配置文件，所以我不太清楚发生了什么。
答案1
这实际上并不是最好的解决办法，但我只是手动调低了风扇，这样我的服务器就不会太吵了。
echo 170 > /sys/class/hwmon/hwmon0/pwm2
