Me personally i don't use sensors for this because it is more cpu heavy then getting the numbers from a file.
Your fanspeeds are stored in /sys/class/hwmon/hwmonX/fanX_input (were X are numbers).
With the
cat command you can get the rpm out of that file and it almost takes no cpu to do! But because these folders sometimes switch it is best to run my script at every boot.If you run this script (best at every boot via /etc/rc.local) then you have all the hwmon folders and names stored in /etc/hwmon.
Now you know which folder belongs to which HardWareMONitoring device (name).
