Thanks!

On the readme, you should change the last line with (wrong path):
sudo emacs /etc/default/thinkfan # change START=no to START=yes

And on my T440s I have the following sensor's locations:

# find /sys/devices -type f -name "temp*_input"
/sys/devices/virtual/hwmon/hwmon0/temp1_input
/sys/devices/platform/coretemp.0/hwmon/hwmon2/temp3_input
/sys/devices/platform/coretemp.0/hwmon/hwmon2/temp1_input
/sys/devices/platform/coretemp.0/hwmon/hwmon2/temp2_input

Thanks!
Seems to be that sensors keyword is not longer supported. I had to use hwmon instead:

hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon5/temp1_input
