Experiencing Issues! CPU Overheating During Startup at 100°C
Experiencing Issues! CPU Overheating During Startup at 100°C
Here is the rewritten version:
There are only two possibilities that stand out. The first is that the CPU cooler isn't making proper contact with the processor. The cooler bracket could be damaged or not functioning correctly. The surface of either the cooler or the processor might be warped and not flat.
The second possibility is that excessive voltage is being applied to the processor. This might stem from incorrect BIOS settings or a faulty motherboard. Please review the overclock settings in BIOS.
For the most part, I've ruled out the CPU cooler as the main issue. Poorly applied thermal paste wouldn't cause such rapid temperature spikes. This seems more related to the cooler not being properly installed or making contact.
I mostly eliminated the cooler problem because my temperatures remain normal when I don't change the BIOS settings I previously described, and I'll revert to them if I use the method I outlined earlier. Regarding the motherboard, it's possible it could be faulty.
Reset the BIOS to its default configuration. Then check if the CPU temperature reaches 100°C again. This should clear any overclocking issues.
(I noticed you attempted this.)
Yes, I've done this several times and it resolves the problem, though it brings me back to where I began. Also, I haven't started overclocking yet—just disabled EIST, Turbo Boost, and Intel Enhanced Turbo, leaving everything else at its default settings.
One thing that comes to mind is the I7-8700K with 300 series motherboards. The combination of multi-core enhancement and XMP led to an automatic overclock. Honestly, I'm unsure if this is possible on this specific processor/motherboard setup. It's worth considering.
I believe it could be a possibility, though unlikely, since I usually enable XMP and the system runs well without modifying BIOS settings.
There might also be an issue with the Corsair H115i AIO cooler. Is this a new build? Do you have experience with this model to confirm if it's properly installed or if the pump is functioning correctly?
As before, I'm confident the cooler isn't the problem. This isn't my first system—I built it in November 2016, and this is my second build. I'm not unfamiliar with these components.
You can inspect the surfaces using a straight edge (trying different angles to spot any light underneath) to check for deformation.
Initially, I suspected the cooler might be faulty, so I removed it. I noticed that the back plate or mounting bracket was slightly protruding through the motherboard, possibly affecting contact with the CPU. I sanded it down about 1mm and used a caliper to ensure even removal.

If you're correct, your readings reached 60°C on a CPU core during boot? That's unusual. In BIOS settings, you should expect around 32°C unless the PC is running in extreme conditions.
What does the Vcore display in BIOS show?
I suspect that if the cooler isn't warped, the impeller might have snapped off the motor, causing vibration without moving coolant effectively.
Under normal BIOS operation, temperatures should stay in the 30s range, but after disabling EIST, Turbo Boost, and Intel Enhanced Turbo and saving the changes, I saw temperatures jump to 60°C and then rise to over 70°C. The BIOS shows around 1.200v. It doesn't seem like the pump is faulty—both the outlet hose and radiator get quite warm.

Do you have another CPU cooler you could install? A different, functional cooler would help verify if the Corsair H115i is the issue.
I currently only have the Intel stock cooler, and previous attempts didn't yield significant results. Under normal conditions, the temperatures were too low to draw conclusions.
Consider trying the automated overclock method. Begin by choosing a lower overclock setting. Once applied, keep an eye on CPU temperatures. If they stay within acceptable limits, it indicates the overclock is viable. Proceed with further adjustments based on this outcome.
If temperature issues reappear, treat them as another observation. Pause and revert all settings except the multiplier. Retry the process and continue monitoring.
