Super High Temps on i7-7700k Overclock, Advice Please!

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:
Asus ROG Strix GTX 1080
G.Skill Ripjaws V 3200mhz
Asus ROG Striz z270e
EVGA 850w G2 PSU
2 140mm intake fans on rad, front of case
3 120mm exhaust fans on top
1 140mm exhaust on back.

  1. Hi adotburr :)

    Prime95 is a torture test alright and will push your CPU to the max. It's like putting your foot flat to the boards out of gear and leaving it there. You would not do that would you.?

    I much prefer AIDA64 as the stress testing is less severe and the package is more comprehensive.

    Much depends on your Bios skills for Overclocking the CPU and your Core Voltage plays a big part in attaining your MAX Overclock. The higher core voltage to maintain stability the higher the temperature and the difference is exponential.
    It also depends on your cooling system as to how far you can push it and no two CPUs have the same capability. (Silicon Lottery)
    Very often the difference is only 100-200MHz and it's best to have a stable system rather than chasing records.
