我的笔记本因为 CPU 达到临界温度而突然关机的情况已经发生过好几次了，如日志中所示。然而，奇怪的是，CPU 风扇此时并没有以最大速度运行，而是安静地以较低的速度运行，而且在我看来，风扇并没有及时变快。
我已经彻底清理了笔记本电脑上的灰尘（不是很多），剩下要做的唯一一件事就是对 CPU 进行更好的导热，但这将是一项艰巨的工作！
以下是关机时最后的日志条目的示例：

是否有可能影响风扇的行为并使其对温度升高做出更快的反应？
答案1
幸运的是，自从我更新到华硕 X571 的最新 BIOS 版本 311 后，问题就解决了。
看来这也是 BIOS 版本 310 引入的。在我更新到版本 310（当时的版本）后不久，问题就开始出现了。更新到 BIOS 版本 311 后，过热关机问题就消失了！
