Overclocking i7-7700k at high temperatures – tips needed!
Overclocking i7-7700k at high temperatures – tips needed!
New build, my first high end build and overclock experience. GPU benchmark passed in 3dmark here.

It's an custom loop on a 280mm rad cooling the cpu, and I've got it up and stable at 4.7ghz at 1.3 core voltage. Even at this fairly modest (I think) OC, my temps in Prime 95 Tourture Test get well into the 80c and even mid 90c. It's stable, but seems pretty hot, especially considering my cooling solution.
I understand most are able to push to 4.8 or 4.9 and some chips even to 5.0. At this point, I'm less concerned about the extra power and more about the fact that my temps seem to be running high compared to others on a modest overclock with a high end liquid cooler. I'm concerned there's something else going on that I can't figure out.
Specs as follows:
i7-7700K
Asus ROG Strix GTX 1080
G.Skill Ripjaws V 3200mhz
Asus ROG Striz z270e
EVGA 850w G2 PSU
NZXTh440
2 140mm intake fans on rad, front of case
3 120mm exhaust fans on top
1 140mm exhaust on back.
Hi adotburr
Prime95 is definitely a tough test and will really stress your CPU. It’s like leaving your foot flat on the boards without protection. You wouldn’t do that, would you?
I tend to favor AIDA64 because its stress tests are milder and the package offers more thorough coverage.
The outcome largely depends on your BIOS capabilities for CPU overclocking, and your core voltage is crucial for achieving maximum overclock performance. Higher core voltage keeps stability but also increases heat, with a significant impact on temperature.
Your cooling solution also matters, as it determines how far you can push the system, and no two CPUs are identical—this is often called the Silicon Lottery.
The difference in performance is usually just 100-200MHz, so having a reliable setup is key.

Often the gap is just 100-200MHz, so a stable setup is usually better than trying to break records.
