It is possible to control the fan speed with this program if your motherboard supports it. Just use the arrows beside the number 240. And you need to run this application as root to be able to control the fans.

Install lm_sensors and run sensors-detect to find out which modules you need loaded.

I have installed lm_sensor and run sensors-detect below is the output

Driver `it87' (should be inserted):
Detects correctly:
* ISA bus, address 0x290
Chip `ITE IT8712F Super IO Sensors' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue:

But I Already installed Qtfan before. How do I proced from here>

You should not need to do anything more than that to get correct fan readings, to check if it works run "sensors" from the terminal, if you get fan speed readings and temperatures it should work in QtFan, if not post the output of
ls /sys/class/hwmon/
and
find /sys -iname 'pwm*'

Thank you,
I managed to install qtfan and it really work.
This is just for displaying right?
Can we use it to control the speed of the fan. Or is there any other project for controlling the fan speed?
