在i8kmon Ubuntu 14.04中设置温度阈值

我的Dell Inspiron 15R出现过热问题，并安装了它i8kmon来控制Ubuntu 14.04上的风扇速度。

这是“ lm-sensors”输出的副本：

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +62.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +57.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +61.0°C  (high = +87.0°C, crit = +105.0°C)

i8k-virtual-0
Adapter: Virtual device
Right Fan:      0 RPM
CPU:          +62.0°C 

即使将温度阈值设置/etc/i8kmon为：

set config(daemon)      1

# Automatic fan control, override with --auto option
set config(auto)        1

# Report status on stdout, override with --verbose option
set config(verbose) 1

# Status check timeout (seconds), override with --timeout option
set config(timeout) 1

# Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt}
set config(0)   {{0 -}  -1  55  -1  55}
set config(1)   {{1 -}  55  70  55  70}
set config(2)   {{2 -}  60  128  60  128}

风扇不应该启动。关于什么可能是错的任何想法？以下是使用选项手动log运行时的副本：i8kmon--verbose

看来温度有误，i8kmon并且没有打开风扇。

根据lm-sensors：

i8k-virtual-0
Adapter: Virtual device
Right Fan:      0 RPM

您只有一个Right Fan，因此左风扇值应始终为-1。您必须将文件中的设置配置更改/etc/i8kmon.conf为以下值：

set config(0)   {{-1 0}  -1  40  -1  40}
set config(1)   {{-1 1}  40  60  40  60}
set config(2)   {{-1 2}  60  128  60  128}
set config(3)   {{-1 2}  60  128  60  128}

在该状态下{-1 0}，没有左风扇，右风扇处于关闭状态{-1 1}；在状态下，右风扇应以低速运行，而在状态{-1 2}下应以全速运行。其他值（例如40 60 40 60）对应于有和没有交流电源时每个状态的温度阈值--min和max-。

您还需要添加以下选项：

# Run as daemon, override with --daemon option
set config(daemon)      0

# Automatic fan control, override with --auto option
set config(auto)        1

# Report status on stdout, override with --verbose option
set config(verbose) 1

# Status check timeout (seconds), override with --timeout option
set config(timeout) 20

最后，您需要i8k.conf在中/etc/modprobe.d/包含行的文件options i8k force=1。
