After having the CPU replaced (it was tested faulty on another system) the temperature is much lower (below 50 degrees when idle).
My conclusion is that the faulty CPU caused the high temperature...

As I stated Before, I use "NoFan CR-95C". A passive cooling for my CPU.
I suppose I can Clean the CPU and cooler from thermal grease and apply new one. A quite tedious job though.
As computer case...

But I get BSOD just after starting when in idle (CPU temp 60-70 degrees).

Right now the CPU Temp is about 80 degrees in idle (60-80 in idle, 80-99 under load). The motherboard seems to be that high Always (maybe something betwen 80-100)

Flipping between 96 and 97 degree Celsius.

I waited some time and run the Intel Diag Tool again and this time all tests passed. It might have been the Prim95 which heated the CPU just Before I begun the first time.

Tested with Prime95 for 5 minutes only and had no errors.
Moved on to Intel Diag Tool which gave me an error quite quickly. See attached txt file for the report.

No I have not overclocked anything. But I do use a special cooling Solution for the CPU with NoFan CR-95C.

I installed the DriverToolKit my mistake after all the driver updates. I have not installed any drivers using it and now its removed.

When running normal mode my computer have run perfectly with the same system config for more then 1.5 years now. No HW has been changed.
Lately I have started to get BSOD unexpected operation (win10...
