Heat under prime 4 screen

Hello Guys

i noticed my P4 bottom under the screen area is blistering hot almost burned my hands after 2 - 3 hours ( although where i put my unit is not closed space), do you experience the same? despite any CPU activities inside the unit, such temperatures are alarming, no fan noises coming out too although frankly no issues shown yet ( beside some screen ghosting which i don’t know if its caused by this overheating ( screen itself is cold),l’m now concerned frying the board, or shouldn’t?
