"CPU Temp" is read by a sensor in the socket of the motherboard. So yes, it's really strange.Thanks for the help. I can’t understand that and I wonder if the TJ-core measurements or the CPU package measurement in AIDA64 is incorrect. No TJMax is applied on it, no conversion is made on the readout.
When I upgraded to a 5820K with the ASUS X99-A motherboard, I noticed that at idle the CPU Package temperature was 10-15 degrees higher than the core temperatures and was around 5C hotter during stress tests. Any Idea why ? My goal is to keep the highest core temperature well under TJ-MAX, and I think TJ-MAX is 87 degree C for the Intel i7-5960X.
Guess the mystery of the CPU Package continues.I guess this was just the 1-st level support, so maybe if you push them a bit they will forward this issue to a higher level and might come with a better answer.I'm seeing a similar thing with my i7-5820K, not that I think HWiNFO is a problem.

So since the CPU package temperature reports the average of highest temperatures in the CPU, it might be catching the FIVR.Here is a screenshot of the temps from both idle and load.
As we say in the USA, don't shoot the messenger. I have seen the CPU Package temp spike up 69°C when gaming sometimes however. I just have a small problem- my package temperature for the CPU is usually anywhere between 4 to 18 degrees higher than my individual core temps.
Looks like tools like HWMonitor and Intel XTU read a different CPU Package temperature value.HWiNFO certainly doesn't apply an offset. I have a system based on a ASUS 99X Deluxe motherboard, with an Intel i7-5960X. Is it possible to do something like that on accident? I attach two screenshots from AIDA64 during 100% CPU load based on my own FPU stress tasks. TemperatureResult = TJMaxValue - TemperatureReading You can post now and register later.

That would explain the difference, since Core Max values are relative to Tj,max but the CPU Package value is an absolute one.I have not... unless I did it accidentally. I thought this might have been an issue with how I seated my cooler (Kraken X41), but after removing, cleaning, and reapplying thermal paste I still get the same strange temperature differences.

The TJMax value is read directly from the processor, and the core temperatures are calculated as: AMD designed this equation to accurately read peak (45C+) and load temps. But package is more well rounded.
