SOLVED Tool fan always on on FAN0

I have a Duet2 Wifi 1.03.
I am having a strange part cooler fan behaviour after upgrading RRF 3. It all worked fine on RRF2.X and 1.X no hardware changes.
I re-did the online configurator since some things changed and the BLtouch wasn't working, now everything is working but the tool head fan.
I have the hotend fan is thermostatically controlled and should come on at 45C plugged on FAN1.
The tool fan (FAN0) should work independently but it only turns on at 45C as well (thermostatic control is off), it never turns off even with an M106 S0. But it will come off if the head is below 45C.
This is my config file.

I can control the fans speeds with the slider in the web GUI if the hotends are above 45C, if the hotend is below 45C the slider control doesn't do anything.
I have looked for answers and read the docs, but I can't seem to find a solution.
Thanks in advance!

@Phaedrux So simple, it worked perfectly.
It was probably my mistake, thanks.
