如何知道CPU风扇是否快要结束生命了?

如何知道CPU风扇是否快要结束生命了?

我有笔记本电脑 Dell Inspiron 15 5570(我不使用仅内置 Intel 显卡的 GPU)并遇到以下问题:

我有 dmesg 的输出:

[170178.959009] CPU7: Core temperature above threshold, cpu clock throttled (total events = 3635)
[170178.959010] CPU3: Core temperature above threshold, cpu clock throttled (total events = 3635)
[170178.959031] CPU1: Package temperature above threshold, cpu clock throttled (total events = 4393)

[170178.959034] CPU3: Package temperature above threshold, cpu clock throttled (total events = 4392)
[170178.959035] CPU4: Package temperature above threshold, cpu clock throttled (total events = 4393)
[170178.959036] CPU0: Package temperature above threshold, cpu clock throttled (total events = 4393)
[170178.959038] CPU6: Package temperature above threshold, cpu clock throttled (total events = 4393)

[170178.959045] CPU7: Package temperature above threshold, cpu clock throttled (total events = 4393)

它显示多次,当我运行时sensors它显示:

我使用的 Fedora 存在用 100% 消耗的 Claws-mail + libnotify 问题(4 个 CPU 中的 1 个和 8 个线程),当发生这种情况时,这是传感器的输出:

我是否应该对此 dmesg 错误采取措施并将笔记本电脑送去修理风扇(仍在保修期内)?我应该对我的笔记本电脑说些什么?我应该等到风扇停止工作(当其中一个 CPU 为 100% 时显示 0 RPM)吗?
