During Thinkfan installation, it should retrieve sensors infos on its own by executing find /sys/devices -type f -name "temp*_input" and fill on its own the file thinkfan.conf with proper data. +++ This bug was initially created as a clone of Bug #1118961 +++
Not to discourage you but you should read more about Thinkfan before creating a series of bug reports. Read the readme from the original package http://thinkfan.sourceforge.net/. The above hack will help you setup simple configuration but current version of Thinkfan favors complex configuration. Simple configuration uses highest temperature from all sensors to modularize the speed of fan. Complex configuration changes speed of fan based on individual sensors. > find /sys/devices -type f -name "temp*_input" Not all the sensors from this list will work. Hardware are too different to implement what you are asking. Package maintainers can do little here. This might be more suited to upstream.
