What is the nature of the problem - I mean is there a temperature problem evolved over time, or is it just you trying to run a more resource demanding game that just cause the computer to heat more than before?
PRIME95 Maximum Heat 6min average temp:85
Idle after prime95 temp:53
Youtube video ~10min
GPU: 62 Min 67 Max
League of Legends
Not only those temps harm the components (cpu temp at least) but also the laptop sounds like a jet engine! Even on youtube videos.
