戴尔笔记本电脑 CPU 温度高达 86°C,而此时风扇全速运转

我有一台全新的戴尔 Inspiron 5000 系列。

我将 Ubuntu 20.04 放在实时 USB 密钥上并运行它。

问题是,即使什么都不做,风扇也始终处于最高速度......

尝试了很多方法之后,问题似乎在于,即使不做任何操作并且风扇全速运转,温度仍然很高(86°C),所以风扇永远不会停止。

传感器、CPU、Ubuntu 或……有问题吗?

只需使用 Ubuntu 20.10 代替 Ubuntu 20.04

Details of the PC :
Inspiron 15 5000 Séries 5502
11th Generation Intel(R) Core(TM)i7-1165G7 Processor (12MB Cache, up to 4.7 GHz)
