Unusual core temperatures displayed by HWMonitor.
Unusual core temperatures displayed by HWMonitor.
This seems logical. The overall package temperature matches what you expect, but the individual cores are showing near-freezing readings. That’s unusual—usually core temperatures stay close to the package temp. I’ve never seen a setup where the CPU temps are so far apart from each other. It looks like your system is running under different conditions than usual.
I’m not surprised by the figures (I understand typical CPU averages), but I’m surprised by the big difference in temperature between the package and the cores. That was mentioned in my first comment.
The "package" temperature is usually measured from a sensor on the substrate, while core temperatures can come from a thermistor inside the chip or from resistance changes in contacts elsewhere. The exact method Intel uses isn't clear, but this difference likely explains the gap between your package and core temps. What cooling system are you using for your processor? What's the temperature of your surrounding environment?
Ambient sits around 79 degrees F with the side panel open; I'm testing the setup right now. The cooling setup uses an AMD FM2+ stock cooler secured to the motherboard with Thermal Grizzly Kryonaut paste. It's working well—temperatures are stable and within range, even during a PCMark test. I've never noticed such a big difference between package readings and core temps before.
