My Bad, I thought the tool fan referend to the hotend fan
Hotend fan is having this issue. It is controlled by the duet gcode.

This morning I have been testing the hotend and every time it runs at full speed, after a heating and cooling cycle.

Do I need the F parameter? I only need it on or off. I know its default is 250 if it is omitted.

You don't need the F parameter. The fan should turn fully on when the indicated hot end temperature rises above 40C and off when it falls below 40C.
