Damage to 5820K is significant but cause remains unclear.
My 5820K is beyond repair, and I'm unsure what led to this. It once handled 4.4ghz at 1.3v with the hottest core staying under 80°C. It's been cooled with a Noctua NH-D15 chromax, which isn't old, and the thermal paste has been refreshed regularly. The photo I shared is taken under normal operating settings with some RAM tweaks. Recently, the package temperature isn't reading properly—it worked just fine a few days ago. If I leave everything stock and XMP enabled, it stays below 60°C. However, without overclocking, the core temps never exceed 90°C, and the package only shows around 55°C. Plus, I set the max CPU temp to 85°C in BIOS before shutdowns occurred. What's happening? Did something go wrong, or is the system failing?
Reset the CMOS and see if it resolves the issue. If not, verify whether a newer BIOS version is available. There might be a voltage setting affecting temperature readings due to thermistors inside the CPU. It seems to be an Intel or AMD problem—I’m not sure which one. @ShrimpBrime
I realized the CPU wasn't damaged; the issue stemmed from HWMonitor malfunctioning when I set a manual shutdown temperature in BIOS. At the time, my OC ran at 4.2GHZ with 1.25V. I adjusted it later to maintain lower temperatures. Thanks to Zando Bob and SpiderMan for their guidance—I was mistaken! Appreciate all the feedback.
