我最近将 CPU 和 MOBO 更换为安装在 Gigabyte B660M DS3H DD4 主板上的 i5-12400。从那时起,我一直有错误的motd
温度读数:

改变之后我执行了lm-sensors
程序并sensors
得到了以下结果:

Core 5: +34.0°C (high = +80.0°C, crit = +100.0°C)
为了确保读数正确,我快速重启到 UEFI,显示 38.0°C。系统motd
再次启动时显示46.0 C
。
我能解决这个问题吗?
答案1
“每日消息”的温度采样时间是在大量登录相关代码刚刚执行之后。因此,处理器会稍微热一点。稍后再来时,它已经散发了热量。
答案是,这两个读数在当时都是准确的。
也可以看看我的 Ubuntu 论坛回答了这个问题,并支持 turbostat 数据
