我的 Dell XPS 9700 和 Ubuntu 23.04 经常遇到一个问题：CPU 温度升至约 60°C，导致风扇发出烦人的声音。CPU 上没有明显的负载可能导致这种情况 - 至少据我所知。sensors下面是显示问题的输出。
这个问题是在之前的安装中出现的，这就是我全新安装 Ubuntu 23.04 的原因。对我来说幸运的是，这解决了大约两周的问题。现在我又回到了原点。
我在之前的安装中尝试的是使用 i8kmon 等工具来“微调”风扇速度，但这只会导致系统振荡（温度和噪音方面）。我知道这台笔记本电脑在空闲条件下能够承受相当低的温度。所以一定有什么事情发生...
我可以做什么来诊断这个问题？我需要提供什么信息吗？
