CPU packet temperatures vary significantly compared to my CPU core temperatures.
CPU packet temperatures vary significantly compared to my CPU core temperatures.
Your CPU core temperatures match your cooling setup well. At idle they hover around 22-23°C, while the package temps sit in the 45–degree range. I’m puzzled because changing only the Vcore hasn’t affected these readings. The 5.0GHz stable overclock at 1.38V Vcore is functioning properly, with temperatures peaking near 73°C during stress tests. Under load, package temps jump to about 95°C. I’m unsure why this happens and feel uneasy about those high readings. Could running at such high package temperatures be harmful? Why is there such a big difference between core and package temps? Any advice would be appreciated!
the idea of keeping the system idle at 20°C seems unlikely unless your setup is unusually cool. most likely, the actual readings come from the packaging rather than the internal components. the 9600k does generate heat, especially at higher voltages, which explains the higher idle temps you mentioned. what cooling methods are you considering?
The images come from HWinfo. I'm testing a Noctua NH-D15 with two fans. I also have three 120mm intake fans, two 140mm top exhaust fans and one 120mm rear exhaust fan.
The images come from HWinfo, but I'm checking the actual sensor data. With your setup—two 120mm intake fans, two 140mm top exhaust fans, and one 120mm rear fan—your core temperatures should reflect real airflow and cooling performance. If HWinfo gives misleading readings after you changed the CPU paste, it might be due to thermal lag or incorrect calibration. Double-check sensor placement and ensure the paste improves heat dissipation without overheating components.
It was quite late when I replied. Usually I’d say core temp is the more reliable sensor, but 22-23°C idle doesn’t seem correct unless your ambient is around 10°C. A reading of 95°C under Prime95 at 1.38v feels a bit extreme but not impossible. Could you run a lighter stress test with Cinebnech 15 and Cinebench 20, then let me know what you see?
