Hey Guys,
Using HWiNFO64 to get temperature readings for my laptop. At the moment, it says my 'Cpu0' temperature is less than 50C (~47C) whereas the 'Cpu0 package' temperature is over 100C. What does this mean, bearing in mind my processor is an AMD A8-4500M Quad core processor and im not gaming at the moment, just watching videos and browsing etc.?
Thanks

I assume that CPU 0 refers to your CPU. If there were multiple CPUs in a single system, they'd be CPU 0, CPU 1, CPU 2, CPU3, etc. If there were other entries like those, then I'd think it was referencing each individual core, but as it is not, this is the most likely possibility.

I don't know what CPU 0 package means. It might be the temp sensor for the motherboard socket whereas the first is the sensor for the CPU. Those old chips often only had a single on-die temp sensor, unlike modern designs that have a sensor for each core. These are known for being less accurate than on-die sensors, but that is far too extreme of a difference to be just that.

Try another few programs, like speedfan, to see if they agree with what you're using...

Regardless, I doubt your CPU is truly anywhere near 100 degrees C. That is far beyond the limits of the processor and it would quickly fail even if the system failed to shut down as it is supposed to in the event of such temperatures. Those CPUs aren't built to handle temps even above 80 and would simply fail if they reached, let alone breached, the 100 degree mark in C.

Thanks a lot.

In other programs my temps are much more 'normal': only 75C under load using a few other programs, including speedfan. I presume that HWiNFO isn't working properly with my system. Thanks a lot.
