So I recently bought my own computer, well built it. And I'm currently using a I5 9600k with a Be Quiet pure rock slim. And recently I was streaming csgo until i changed to battlefield 4 and streamed and played for no problem for like 20 minutes until everything just slowed down and lagged. So I restarted and saw in the bios that the CPU was at 88 celsius. I was thinking of switching the thermal paste instead of using the stock one but i was wondering, do you think I harmed the cpu in anyway? Cause im scared of it dying or anything else or do you think switching thermal paste will just solve it and everything is fine?
