Thinkfan

Please read the config manpage thinkfan.conf(5) before playing around with this.

This is NOT a working config file that can just be copied. It is only meant to give a rough idea what can be done. In particular, don't copy & paste the fan speed config! Think about what you're doing.

If you don't know what temperatures are right for your system, you should not be using thinkfan!
