sudo thinkfan -n 时显示
WARNING: Using default fan control in /proc/acpi/ibm/fan.
Module thinkpad_acpi doesn't seem to support fan_control

好像14.04能自己控制风扇转速了?

为什么我的风扇再热也不转啊？我的也是
Using default fan control in /proc/acpi/ibm/fan

参考：http://thinkwiki.de/Thinkfan
sudo apt-get install lm-sensors
sudo sensors-detect # 一路yes，最后有个提示，就是下面的命令
sudo start module-init-tools

find /sys/devices -type f -name "temp*_input"
我的显示如下：
/sys/devices/platform/coretemp.0/temp1_input
/sys/devices/platform/coretemp.0/temp2_input
/sys/devices/platform/coretemp.0/temp3_input
/sys/devices/platform/coretemp.0/temp4_input
/sys/devices/platform/coretemp.0/temp5_input
/sys/devices/virtual/hwmon/hwmon0/temp1_input

4：编辑 /etc/thinkfan.conf ，另外加入温度侦测（ 有thermal文件，就不需要这部分），我的内容如下：
sensor /sys/devices/platform/coretemp.0/temp1_input
sensor /sys/devices/platform/coretemp.0/temp2_input
sensor /sys/devices/platform/coretemp.0/temp3_input
sensor /sys/devices/platform/coretemp.0/temp4_input
sensor /sys/devices/platform/coretemp.0/temp5_input
sensor /sys/devices/virtual/hwmon/hwmon0/temp1_input
