Ubuntu 20.04 过热问题,错误信号?

Ubuntu 20.04 过热问题,错误信号?

我在 Ubuntu Desktop 20.04 上安装了 LENOVO ThinkPad L13 Yoga。

几天来,Ubuntu 一直崩溃并突然关闭。

查看日志journalctl显示问题出在过热,

Jun 30 13:13:19 siavash-fra thermald[1184]: critical temp reached
-- Reboot --

虽然没有过热的迹象。所以我用 监控温度sensors。以下是启动后没有运行任何任务后的值:

实际上感觉不到任何温暖。这可能是错误信号吗?温度能在不到 2 秒的时间内达到如此高的温度吗?

我同时使用 Windows,没有出现过热或崩溃的情况。顺便说一句,它显示了,fan1: 0 RPM但我能听到并感觉到风扇在运转。
