i7-8700K Temperature Spikes?
i7-8700K Temperature Spikes?
I just increased the clock speed of my 8700K to 4.9 GHz, managed to reach 5 GHz at 1.35V, but I reduced it slightly after noticing temperature spikes in the HW Monitor. At idle, I’m around 41°C, and for a brief moment it reaches 60-70°C before dropping back. Is this typical behavior for this CPU?
If helpful, I’m using a Thermaltake TG-3 that’s been sitting on the shelf for about three and a half years. Could that be the reason? It seems to run fine during use, not overly hot.
Specs:
i7-8700K @ 4.9 GHz & 1.32V
ASUS ROG Strix Z370-f
Corsair H80i v2
EVGA GTX 1080 Ti FTW3
Corsair Vengeance 2 x 8 GB @ 3000 MHz
EVGA SuperNOVA 750 G3
The voltage situation is quite challenging and requires careful attention.
1. It lacks the same safety features as a GPU, making it more prone to damage if mishandled.
2. Even with a small overclock, heat buildup can occur, depending on cooler paste, fan speed, and thermal paste quality.
Your motherboard is designed for CPU overclocking, while your processor is a high-performance model (like a coffee lake CPU). It supports significant overclocking, and temperatures around 60-70°C are generally safe. CPUs and GPUs can handle up to about 90-95°C, though they may struggle beyond that. The idle temperature is likely lower, possibly with background processes running—check the taskbar for details.

Your motherboard is designed for CPU overclocking, while your processor is a high-performance model—ideal for significant overclocking. Temperatures around 60-70°C are generally safe, as CPUs and GPUs can handle up to about 90-95°C. However, they may withstand even higher temperatures.
The idle temperature is likely (I assume), with some background process running; it might not appear in the taskbar but can be verified via Task Manager.
Happy overclocking!
Thanks for all the feedback. I plan to skip the voltage settings and experiment further. I’m also wondering if my thermal paste is still good or needs replacing. I’m considering ordering Arctic Silver MX-4, which should have a long shelf life. Since I don’t build many computers, I’d rather not waste a tube of paste (sorry for the pun).
