ubuntu 16.04 pwmconfig'没有工作风扇传感器'

我正在尝试控制我的 ubuntu 服务器的风扇速度。它有一个 Asrock 970extreme4 和一个 AMD 8350。

我安装了 fancontrol 等，但是当我运行 pwmconfig 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.

这意味着我没有获得 fancontrol 配置文件，所以我不确定发生了什么。
