FCFANS is optional value i can try to remove it.
Strange but now then i removed /etc/fancontrol the output of pwmconfig look
like this:

# pwmconfig revision 6166 (2013-05-01)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
   hwmon0 is acpitz
   hwmon1 is radeon
   hwmon2/device is k10temp
   hwmon3/device is nct6775

Found the following PWM controls:
   hwmon3/device/pwm1           current value: 255
   hwmon3/device/pwm2           current value: 108
   hwmon3/device/pwm3           current value: 255

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon3/device/fan1_input     current speed: 0 ... skipping!
   hwmon3/device/fan2_input     current speed: 0 ... skipping!
   hwmon3/device/fan3_input     current speed: 0 ... skipping!
   hwmon3/device/fan4_input     current speed: 0 ... skipping!

There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.

Maybe this is the root of problem and i have dead fan sensor?
I will play with it more to catch why it ran fine before and wont now.
