I7 8700K Hot Or fan problem
The setup is almost identical to mine, using the same motherboard and 8700K. It’s clear that at 5GHz the CPU will overheat. Knowing your vcore is essential for successful overclocking, since most heat comes from the voltage maintaining 5GHz. Your cooling system works well with fans directing air through the radiator, into the case, out the top and back, but a stronger cooling solution or a lower vcore would be better for a 5GHz boost. A idle temperature of 40°C is acceptable, though gaming pushes it to around 80°C. For a more accurate vcore measurement during heavy loads, running Prime95 v26.6 would help identify possible adjustments. I currently use an Offset/adaptive vcore and at 5GHz it stabilized at about 1.327; lowering it to 4.9GHz at 1.278v for my overclock achieved better results. I also tried resetting the vcore in BIOS, but it keeps reverting to auto. I’m concerned about auto-overclocking at 5GHz because voltage fluctuations can cause excessive heat.
Shmoochie shared some insights about their setup. They mentioned similar motherboard and 8700K components, but noted overheating issues at 5GHz due to high CPU temperatures. They emphasized the importance of knowing the Vcore for overclocking, especially since heat output is directly linked to voltage. They also discussed cooling needs for a 5GHz boost and shared their experience lowering the Vcore to manage heat better. Additionally, they expressed concern about auto-overclocking at 5GHz and suggested checking BIOS settings manually.
Karolm shared his experience about his setup, noting similarities with another user's configuration. He mentioned that at 5GHz, the CPU tends to overheat and emphasized the importance of knowing the Vcore for safe overclocking due to heat from the voltage. He pointed out that while his current setup is decent with good cooling, a stronger cooling solution or lower Vcore might be necessary for a 5GHz boost. He also shared that adjusting the Vcore during Prime95 tests helped him identify a stable value around 1.327 at 5GHz. Additionally, he discussed issues with manually setting the Vcore in BIOS and the importance of using the correct settings to avoid auto-overclocking complications. He recommended checking the Gigabyte BIOS documentation for specific guidance on his board and configuration.
