Hi , I have a set of heater bed cooling fans which in my cura end gcode I've added M106 P2 S1 H0 T30 .
AND added M106 P2 S0 H-1 at the start of my cura start code, BUT you problem is this get executed after the bed and nozzle has reached temperature , so fans are on until the temperature reached and then switch off .

Is there a macro which gets called first ?

You can create a file called start.g which is called at the very beginning of a print.
