怎样打开风扇？

我有一个相当老旧的系统76笔记本电脑并且风扇不再自动打开，因此 CPU 过热并且笔记本电脑一直关机。

我打开它并清理了灰尘。我还按照如何控制风扇速度？并且它成功了。一次。即，我（按root）安装了lm-sensors和fancontrol包，运行了sensors-detect，将其添加coretemp到了/etc/modules，运行了service kmod start，运行了pwmconfig，然后fancontrol打开风扇 - 我听到了噪音，感觉到热空气从排气口逸出，笔记本电脑正常运行。

但是，我重新启动了，现在风扇不转了。我从头开始走这条路（apt purged thelm-sensors和fancontrolpackages &c），但现在pwmconfig失败了

未安装支持 pwm 的传感器模块

此时此刻，我只想打开风扇，该死的温度。我该怎么做？

PS. 的输出sensors是

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +28.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +28.0°C  (high = +105.0°C, crit = +105.0°C)

acpitz-virtual-0
Adapter: Virtual device
temp1:        +30.8°C  (crit = +112.0°C)

nouveau-pci-0100
Adapter: PCI adapter
GPU core:     +0.90 V  (min =  +0.90 V, max =  +1.17 V)
temp1:        +51.0°C  (high = +95.0°C, hyst =  +3.0°C)
                       (crit = +105.0°C, hyst =  +2.0°C)
                       (emerg = +110.0°C, hyst =  +5.0°C)

此工具应该可以工作，即使pwmconfig无法检测到可管理的传感器，此工具也应该可以工作：https://github.com/ichiriac/ubuntu-smart-fan
