Fan only goes to 50% in code despite setting, feel i'm missing something

Of course you can set the fan speed in many placed in G-Code, even though you tell fan to spin 100% the sliced can quickly change it back to 50%
Open the G-Code that will not allow you to set G-Code to 100% with Note Pad ++ search for M106 to see it it may be changing fan speed after your setting it to 100%

I do understand this. I am not explaining myself well i guess. My slicer should be slicing and varying fan speed and it is not. I do see only one M106 and it's at fan minimum. The piece does not have any short layer times and is not very many layers so perhaps that's why the slicer is only calling for S127 (50%)
