AMD Athlon 64 X2 5400+ overheating

[imarex]

Hello.

I've been having problems with this CPU for ~2 years now.
It happens like this.

I bought a new PC. It was pretty good at that time. I was playing Crysis one day and the PC immediately shut down.
Turns out the CPU seems to be overheating. I use Core Temp to see the temperature. (I've tried many other programs, but they're the same.)

When I play games or do rendering and whatnot, the temperatures start to rise. When at ~100°C, the PC would turn off.

I've reapplied the thermal paste multiple times. 90% of the time it just overheats. Altough there are some times when for periods of time i.e. ~2weeks - few months it just works.

The voltage seems to be normal - 1.3000V and I haven't tried over-clocking or anything.


Any help? Could this be a faulty temp sensor or what?

Ok we need to know what PC case you are using and what cpu cooler you use, also use Hardware Monitor, are those temps defo C and not F ?

This is my PC case - COMPUCASE MIDI BLACK ATX, but I've opened a side.

I have the stock CPU cooler. I guess that should be ok for normal everyday operations and games.

And the temperatures are definitely Celsius. And thery're the same with Hardware Monitor as well as Core Temp.
