I updated to the latest EasyTune software suggested by APP center and the SmartFanControl under EasyTune is gone.
I tried and followed the instruction on gigabyte website to remove the old version of EasyTune software but the option for SmartFanControl is till gone.
I needed the fan control badly as I have 2 Corsair H110 connected to the motherboard and they now run at about (800~1000rpm) which is not enough to cool my components.
I also looked into the BIOS but there isn't any option to even change setting for PWM fan speed.

old version has it
