Hello, every time it's over ca. 25° Celsius my switch gets Blackscreen in-game sometime I can press power button off and on and can get in to the home menu again or I can hold it to my ac in my car and get the Home menu back but not in-game. My switch runs at CA 37-40° Celsius when it gets the Blackscreen. My fan ist working and changing thermalpaste didnt helped. What can it be?
