一直以来以为是 CPU 使用过度问题,经常的风扇发狂般的响,
近来回想,以前 Ubuntu 6.10 时,在 Dell D620 中,每天不间断跑 SEIT@home CPU 永远100% 时,也没有这种现象的哪,

硬盘温度...
$ sudo hddtemp -n /dev/sda
WARNING: Drive /dev/sda doesn't seem to have a temperature sensor.
WARNING: This doesn't mean it hasn't got one.
WARNING: If you are sure it has one, please contact me (hddtemp@guzu.net).
