Don't worry i'm at ~95°C right now on ESO (on my laptop) and have everything on low-medium.
I have a cooler fan underneath it but it has shut down due to overheating a few rare times during peak temperatures in summer.
It's 4 years old now and I have dusted it thoroughly last week.
In other words, you're not alone
(In fact it's even at 100°C right now, while being afk in town)
