As shown here: https://github.com/SoftFever/OrcaSlicer/wiki/Auxiliary-fan The fans need to be named fan 1, fan 2, fan 3 etc, I propose a update to the M106 gcode to be able to name your fans, This allows the M106 P1, P2 etc commands to still work but also allows you to use the fan name.
You just need to name the fan map to what you name your fan in the config.

[gcode_macro M106]
description: "Set fan speed (Orca compatible)"
gcode:
{% set fan_map = {
0: "CPAP", # Orca P0 → CPAP blower
3: "EXHAUST", # Orca P3 → Exhaust
} %}
{% set p = params.P|int if 'P' in params else 0 %}
{% set fan = fan_map[p] if p in fan_map else "cpap" %}
{% set speed = (params.S|float / 255 if 'S' in params else 1.0) %}
SET_FAN_SPEED FAN={fan} SPEED={speed}

[gcode_macro M107]
description: "Turn off fans. No P = all, P# = specific"
gcode:
{% set fan_map = {
0: "CPAP", # CPAP blower
3: "EXHAUST", # Exhaust (or remap as needed)
} %}
{% if 'P' in params %}
{% set p = params.P|int %}
{% if p in fan_map %}
SET_FAN_SPEED FAN={fan_map[p]} SPEED=0
{% else %}
RESPOND PREFIX="warn" MSG="Unknown fan index P{p}"
{% endif %}
{% else %}
# No P → turn off all mapped fans
{% for f in fan_map.values() %}
SET_FAN_SPEED FAN={f} SPEED=0
{% endfor %}
{% endif %}
