While running a big installer that unpacks a heavily compressed file I noticed that my PC crashed. I started investigating and I came to the conclusion that it was crashing because of high temperatures, but:
1) I have a Corsair 275R Airflow case, which has a very good airflow
2) the wiring is almost perfect, there is nothing that might block airflow
The only big downpoint is that I'm using the stock cooler, but in any case I don't think that the CPU should reach 100° or more even with the stock cooler.
Also I tried something "bad": i took off the back panel of the case and while the CPU temp was over 100° I put my finger on the backplate of the mobo where the CPU is installed and it was not hot, I could have kept my fingers there for hours before I could get burned.
Now my question is: could it be that the sensors are reading wrong? Shouldn't that specific part of the mobo, being SO close to the CPU be hot as hell, or am I wrong?

Also it looks like the CPU doesn't throttle, which is weird..
