In your gcode files there should be M106 lines that tell the fan to turn on (Example: M106 S255 would be fan at 100%). It looks like your Initial Fan Speed is at 5% (M106 S12.8). There are very few fans that will start to turn at a speed that low.
If you zip a gcode file and post it here it would be helpful.

It doesn't matter where I set the speed the fans will not come on.

If that is a single extruder printer then go into Machine Settings. On the Extruder tab is a box for the fan number. It should be set to "0". It's the fan number, not the number of fans.
M106 S255 P1 is trying to start Fan #1 and your cooling fan is likely wired as Fan #0.
