Part fan turning on at print start

[domenick_s 3]

I am running the latest Cura. This might be something I never noticed but I would like to stop.

After slicing a part I would place the G-Code on a card place in my printer, find the file and press start.

The first thing that happens is the part fan comes on, then the bed and nozzle come up to temp and then the part fan shut off to do the first layer.

I checked the G-Code and first lines of code set and turn on the bed and nozzle temps. Next is my Start code with the first line being M107.

No matter what I do the part fan always comes on and stays on until the M107 is read. I can manually move it in front of the temp start up and it works fine.

Any thoughts would be helpful.
