A:AnswerMine definently gets warm but i havent had it over heat yet i would reccomend maybe a laptop cooling pad if you game on it with general use tho it stays cool as far as ram i am running 32gb
A:AnswerI don't know about the other games but just on 8gb I was able to run Valorant at max settings 60fps smooth. 16gb RAM should improve results in the other games, especially if they're heavy on memory.
A:AnswerYes, I did it two weeks ago. Pretty easy youtube it. Add a stick of ram it was $23 at Amazon for same stick that's in there already now I have 16 gigs
