maybe it's just your laptop's heat (the cpu/gpu), your hand have a temperature about [18 C] barely can do anything to your laptop's avg temperature
[65 C], just make sure that the small air vents aren't closed/covered by anything, many laptops have them at the bottom so you gotta lift it a bit with something, or just get yourself a cooling pad would help a bit
**another thing to know most of laptops have some heat issues**
