用sensors测的温度如下:
[sky@sky cpufreq]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +57.0°C (crit = +97.0°C)
temp2: +48.0°C (crit = +126.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +59.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +55.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +57.0°C (high = +86.0°C, crit = +100.0°C)
在windows下温度平均只有50度左右,但是想不通为啥在arch下温度会偏高。也用了ondemand控制cpu频率:
[sky@sky cpufreq]$ cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009

有人是这种情况么?
