Answer to "How do I find my model number?"Hey! sorry for the late response, but on the HP x360 laptops the model number is in REALLY small print on the back, not the back of the screen, but the bottom of the computer where it says "Made in taiwan" or "made in china" or whatever.
Answer to "What can I do about an overheating laptop?"Sorry for the late response.... The Hp pavilion x360 laptops are built with a intel M series processor and integrated ram/video. the M series was designed to be fanless, the motherboard will melt before the processor craps out... That being said, there is not a fan inside of these.. I took mine apart because I was curious and found this out. They run hot, but dont be scared, laptops are designed to be able to withstand high temps.
