Why the fan connected to FAN1 never stop even with M106 P1 S0 ? it just slow down

Because if you select thermostatic mode, RRF assumes that you want it to turn when the temperature is above the set point ni order to protect something from overheating. So it protects against turning the fan off until the temperature drops.

thank you dc42.
Can I put in the config two or more commands for the same fan?
I want the FAN1 turn on if the bed is above 50° AND if the cpu or any driver are above 40°C -
@paboman yes you can specify Multiple heaters and temps using H#:#:# and T#:#:#. Replace # with your numbers.

You can only specify one temperature range H<low>:<high>, or alternatively a single temperature. So you will need to choose one temperature between 40C and 50C for the fan to come on.
