我有一台运行 Ubuntu Jaunty 的 Acer Travelmate 2420。它相当旧，有时会因过热而死机：

这传感器命令向我显示了相同的限制，但没有告诉我这些是哪个组件的上限。我运行传感器检测检查，但是结果告诉我机器没有传感器或者不受支持的传感器。
那么，我该如何理解下面的输出？
$ sudo sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +59.0°C (crit = +85.0°C)
temp2: +51.0°C (crit = +77.0°C)
在我打开笔记本电脑并在 CPU 上涂抹导热膏之前，我想知道这是否真的有帮助。
答案1
传感器命令在我的 Intel Core 笔记本电脑上给出相同的输出。它读取的两个传感器很可能是 CPU 和 GPU。
我对在旧笔记本电脑上重新涂抹导热膏感到担忧。很可能是因为通风问题，导致笔记本电脑经常过热。两个都传感器。我关心的是清除灰尘并确保所有风扇都正常工作。
