[SOLVED] Why is the forth core of my CPU is 104℃?

[M7mdJan]

The forth core of my CPU is 104℃ and the rest are in average of 30℃. And I stress tested my CPU via aida64 extreme and i noticed that one core was a lot hotter then the rest of them, they were actually cold.
The max each core did hit during the test was:
Core1: 36.0℃
Core2: 32.0℃
Core3: 22.0℃
Core4: 104.0℃
Core5: 27.0℃
Core6: 22.0℃
I have another problem of getting crashed in my games like GTA V and Witcher 2, the games are running normally in the beginning but after 10 to 15 minutes it exits and closes the game.
My CPU is: i5-9400F
and my GPU is: RTX 2070 duke.

sounds like a faulty sensor in the cpu. Either that or the monitoring program you are using isn't reading the temp right. I would start by using a different monitor program, and if that shows the same temp, reseat the cpu in the socket and check for any bent or dirty pins. after that if still no go, yeah probably return the cpu as faulty.
