Good temps for an OC'ed i7???

Hi all!

First post on tom's Hardware. :)

Anyway, I finally finished building my gaming rig. Here are my specs:

Deep Cool Tesseract ATX Mid-tower
Core i7-7700k OC'ed to 5.0GHz
Corsair Hydro H55 Liquid Cooler
16GB Ballistix Crucial Sport DDR4-2400 (XMP Enabled)
NVIDIA GeForce GTX 1050 Ti (Overclocked)
Insignia 520W PSU
80GB Seagate Barracuda HDD
1TB External HDD
Windows 10 Home 64-Bit

I'm very happy I was able to run my system stable at 5GHz! I opened up Intel XTU to stress test it once I was finished. I'm pretty sure my temps are within OK limits, probably a little high, but I wanted to post on here to be sure.

(AMBIENT TEMPERATURE IS 70 FAHRENHEIT OR 21.1 CELSIUS)

At idle, my CPU is averaging 35 to 40 Celsius.
During the stress test, my maximum temperature achieved at full load was 79 degrees Celsius. I averaged 60 to 70 degrees Celsius. Anything above 75 Celsius was very, very brief.

Are these temps still OK?

Thank you! :)

    Yeah these temperature are more than fine, i personally call it safe under 90C during stress test and under 80C during normal everyday use like gaming etc. Also XTU is not good for stress testing, use Intel burn test. https://www.techspot.com/downloads/4965-intelburntest.html and HWmonitor to check temperature http://www.cpuid.com/softwares/hwmonitor.html

    Hi Makentox,

    I downloaded Intel Burn Test and ran a quick stress test, using RealTemp to look at my core temps. Core 1 got up to 90 C, core 2 got to 91 C, core 3 got to 87 C, and core 4 got to 91 C. Now I'm starting to wonder if THESE results are bad. :/

    Did you try to lower voltage? If you cant lower it anymore then u should choose take a risk or lower clock to 4.9 and voltage accordingly. I would be fine with such temperature reading but i cant recommend it to others. IBT will stress hell out of your CPU pushing it to the limit. You dont need to run it for hours like other people do, 10-20mins is enough which shouldnt cause any problem, if it pass play some games, u will notice that temperature is much lower in games so its safe.

    Makentox,

    I just went into my BIOS and changed my core voltage from 1.344V to 1.29V, and ran the burn test again. This time, the maximum temperatures achieved on any of my cores was 88 degrees Celsius, and was still stable at 5GHz.

    EDIT:

    Again, I went into my BIOS and decreased the core voltage down from 1.29 to 1.25V. I opened up Intel Burn Test again, and Core 1 got to a maximum of 81 C, core 2 maxed at 77 C, core 3 at 82 C, and Core 4 at 75 C. I think it's safe to say these temps are good! :)
