Cannon Lake 平台控制器中心在 Ubuntu 20.04 上过热

我的笔记本电脑（Alienware m15 - 2018）平台控制器中心（Cannon Lake PCH）在 Ubuntu 20.04 上过热（未运行任何应用程序），与 Microsoft Windows 10 不同，您能告诉我如何解决这个问题吗？

请注意，我正在使用Ubuntu 安装在外部 SSD 驱动器上，因此 USB 集线器控制器正在管理与系统的通信。

我正在使用“无需第三方应用程序即可获得温度“从这个角度看回答如下：

paste <(cat /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) | column -s $'\t' -t | sed 's/\(.\)..$/.\1°C/'
