I have a dell xps 15 7590 with an intel i7-9750H CPU, and not until recently did my fans start spinning fast and my laptop gets really hot, naturally I tried to figure out what was the issue, so I launched core temp and found out that just idling my cpu was on average about 85 degrees. I tried stress testing it but five seconds after it started the temps hit around 100 and just froze so I shut it down. Any clue as to what could be the issue?
