My Cpu Temeratures is kinda trolling going from 90 degree to 60 when I
So, I have a gaming pc that I built 4 years ago, i7 4790, MSI gtx 970, 8 Gb RAM ,and I tried to kept it as clean as possible, I was playing with it all the time without any problem and it never get ovet 70 to 75 degree celcius at heavy load , until last week, I was playing the game blair witch, and it is not a super demanding game, and I noticied that the cpu is at 100 degree on 4 cores, so I tried to fix this essue by replacing the thermal paste and re-seating the heatsink properly, but sadly, nothing has changed, my cpu reached 100 degree is just 2 minutes and kept working without any noticeable problem and games still smooth, no lag , no fps drops nothing . I almost did everything possible in my hands , cleaned my case, reapplying the thermal past 3 times, arranged my cables to give more space, but nothing was helpful, but found out that when I remove the side of my case the heat is decreased dramatically from 90s to like 50s or 60s at most, at stayed there for more than 3 hours of gaming and I tried to play some heavy games like gears 5 and assassin's creed odyssey, it never get above 69 degree. but the moment I put the side of the case back, it start worming up quickly and reached 90 degree, that's so weird and I don't know what is happening exactly. there is two things I did before this start happening, I first changed my PSU from 450w to 550w, and I updated my bios to the latest available wich is from 2016 for my motherbord.
