   Hey #3dprinting bubble, quick question!

   I have an Ender 3 v2 (2020) here and noticed that the part cooling fan can't be turned off. It's running at full blast as soon as I turn the machine on and doesn't react to the usual M106/107 g-codes either.

   Can anyone confirm these commands are supposed to work on this particular machine? I assume the board (mosfet) is toast.

     @fribbledom Are you certain it’s the part cooling fan? Could it be the heat break fan and either wrong RPM reporting or bad thermistor?

     Yeah, it's the radial part cooling fan on the side.
