OVERHEAT? i7 8700k, NZXT Cracken x62
Hello everyone,
Apologies for the English issues. Thank you for taking the time to read this.
I have a question regarding CPU temperatures—do they usually stay normal, and what are typical readings with these settings?
Last night I assembled my new PC without a graphics card, as it wasn't available yet. Here are the components: https://pcpartpicker.com/user/doctoras69/saved/Lxsr7P
I planned to build something compact, but installing the CPU cooler was difficult; it wouldn’t fit properly because the tubes would press against the RAM slots. Since I’m using a mini ITX motherboard, there wasn’t enough space. So I had to adjust the cooler’s orientation, which is manageable. The labels aren’t perfectly straight, but that’s not a major issue.
I’m new to overclocking and looked at some online guides before trying it. My RAM clocks are around 3200 MHz.
I stress-tested my CPU using CINEBENCH R15 and UserBenchMark. Temperatures are in Celsius.
I’m uncertain about my CPU voltage settings, as they fluctuate rather than stay constant. Perhaps I overlooked some configuration steps.
1) When starting, I tried 5 GHz with this tutorial: https://www.youtube.com/watch?v=CoUtA7DKXhU
But the PC would shut down with temperatures ranging from a minimum of 35°C to above 100°C.
2) Then I used the default 5 GHz settings from my Asus motherboard. The PC didn’t shut down, but it still reached very high temperatures (min: 35°C, max: 95°C).
3) Now I’m running at 4.7 and 7 GHz, with temperatures between 35°C and 85°C.
That’s all I have so far. I found some posts about an i7 8700K overclocked at 5 GHz achieving min 20°C and max 65°C. Is that accurate?
Are my temperatures within normal ranges? Should I consider changing the thermal paste? Might the CPU cooler need adjustment? Are there any BIOS settings I’m misconfiguring?
Thank you again for your time.
Best regards,
if you aim for 5.0ghz you must upgrade your CPU and consider liquid metal cooling.
for testing temperature limits, use prime95 26.6; other tools may produce inaccurate readings.
the video from derbauer uses a highly binned 8700k that has already been delided—this isn’t ideal for general users. it was mainly to illustrate the fundamentals of overclocking.
my 8700k running at 5.0ghz and 1.37v reaches around 70c, but i have successfully delided and used liquid metal.
in the meantime, try 4.7ghz and lower the voltage; you should likely achieve stability between 1.20v and 1.30v. the lower the voltage, the cooler your system will be. keep monitoring with realtemp or hwmonitor, and stick to prime95 version 26.6...
