LeDoyen,
The new system with i13900kf, used to work perfect, I have video with temperatures that prove it. After a while about a week the problem pop ups. After that I order LGA1700 retrofit kit with screws , 1 mm lower than the original one to cover the gap! Now I m experience high temp issues! Its strange...anyway I will check the AIO with a friends system which is the same as the one I used to had. Thank you for your valuable time.
