Hello.
I just received an Akntzcs 10.1" touch screen. I have noticed that when the Pi is powered down the fan comes on full when the screen is connected to its 12v power adapter. The fan seems to be back fed via the USB C lead needed for the touch. I guess its O.K. I haven't seen any smoke but it isn't quite the behavior I want. I might have to think of a way round it, such as powering the screen via a relay unless anyone has any other ideas? The screen can take power via the USB C input but the Pi's USB ports don't give enough for that. I'm interested to know if this is expected behavior.
