1.安装相关的包需要4个包，分别为
dmidecode，lm_sensors，lm_sensors-devel，gnome-applet-sensors

命令:yum install dmidecode lm_sensors lm_sensors-devel gnome-applet-sensors

2.参数设置（可以省略，省略后就完显示全部信息）
进入root :su –
/usr/sbin/sensors-detect (这个是传感器的探测程序)
全部回答yes,如果不要哪个，就回答no,不过一般全是yes

3、测试
输入sensors，就会看到如下的输出了。

[root@main ~]# sensors
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +1.24 V (min = +0.85 V, max = +1.60 V)
+3.3 Voltage: +3.30 V (min = +2.97 V, max = +3.63 V)
+5 Voltage: +5.12 V (min = +4.50 V, max = +5.50 V)
+12 Voltage: +12.04 V (min = +10.20 V, max = +13.80 V)
CPU FAN Speed: 2463 RPM (min = 600 RPM)
CHASSIS1 FAN Speed:4017 RPM (min = 800 RPM)
CHASSIS2 FAN Speed:2191 RPM (min = 800 RPM)
CHASSIS3 FAN Speed: 0 RPM (min = 800 RPM)
POWER FAN Speed: 0 RPM (min = 800 RPM)
CPU Temperature: +62.5°C (high = +60.0°C, crit = +95.0°C)
MB Temperature: +43.0°C (high = +45.0°C, crit = +95.0°C)

gnome-applet-sensors工具是在面板上显示温度，及报警等，支持NVIDIA显卡温度显示
