Core temperature at 20 degrees Celsius difference
Core temperature at 20 degrees Celsius difference
Core 0 and Core 5 display a 20-degree temperature gap under heavy all-core usage. I've installed an Arctic LF II 280mm AIO cooler, re-seated and repasted multiple times to ensure even pressure, but the issue persists. I also experimented with the Thermalright contact frame and the standard ILM, yet no improvement occurred. The same outcome appeared with the 4.5ghz Stock configuration. To confirm, I replaced it with a 12400f and overvolted it to 1.3V to check for uneven core temps. Everything functioned normally. Is this setup normal? Should I consider returning it? I don’t have another explanation at the moment.
If it's not crashing and burning, it's technically not faulty. Try to assign affinity to only P-core 0 of some relatively heavy process and check how it's performing. If it hits close to 100°C then nothing wrong. Not all cores are created equal, sometimes there is the opposite of silicone lottery win - lottery loss. Also check core VIDs and see if it receives less power than the others.
