Ok, I'm getting crazy with this. Any suggestion appreciated.
So a while ago one nut felt on the motherboard. The PC was on but nothing happened. I had the brilliant idea to remove it and than the PC switched off suddenly and never worked again.
Therefore, I bought a new m/b and moved everything. Unfortunately something is not working properly because my processor get overheated very quickly just idling in the BIOS (I see the clock swinging between 100 to 300 MHz when idling), reaching temperatures of 90/92 degrees (Celsius).
However, the two cores never go beyond 50.
I had the stock heatsink, but I changed thermal paste, applied, removed, applied again.
I then bought a new Arctic Alpine 11 heatsink (it's designed to 95W processors, mine is 53W...) and placed it with its pre-applied compound (I think it's MX2).
Nothing to do, always the same symptoms.
Now, I read something around and if I understand correctly the only human readable temperature is the processor one, while the two cores temperature are more an indication of how far are they to the limit than to be interpreted as a real Celisus reading (that's because it's an equation instead of a sensor, while the package's one is a sensor).
I've also read that the extremely high temperature I get on the CPU package could be due to a defective motherboard sensors.
Anyway what it's happening is that the processor doesn't want to die by self-combustion (!) so it throttles itself and slows everything down. Which is a good thing to preserve it, but a bad thing for everything else: the systems is barely usable, too slow for anything.
CPU: Pentium G3258
MB: Gigabyte H81M-S2H
Should I change MB? Processor? Both? Any other suggestions?
All the BIOS reading are confirmed by Linux (bar a slightly different temperature calibration).
