Hey guys!
I just figured it out a fix for extreme temperatures of CPU. I got a complaint from my video editor that the editing suite was not performing well. I checked the cpu performance on MSI afterburner and noticed that the temperature isn't normal. I overclocked my I7 8700K and saw its benchmark results. I noticed that it's temperature isn't oscillating and it's fixed at 100 degree Celsius. I always had doubt on the guy who assembled my PC. So I tried reassembling my cooler master air cooler. I found out this was the issue after benchmarking.
The result - THE SCREWS WHICH WAS HOLDING THE AIR COOLER WAS A BIT LOOSE.
That's it, just 3 turns then it was working perfectly with an temperature oscillation between 90 degree to 100 degree.
I thought this would be helpful for someone!
