High Temps Cryorig H7 with i7 7700k

I'm running a cryorig h7 on my new pc with an i7 7700 and trying to lower my temps. During gaming, I have been near 75 but on prime95 stress testing it's getting up to 95 to 100 degrees celcius. I have reapplied thermal paste 3 times and get the same result. Did I get a bad chip or do I need a new cooler or am I okay? I'm alarmed that it runs this high but I'm not sure if it's normal.

  1. What vers of Prime 95 are you running?

    Should be 26.6.

    Make sure you have the latest Bios for your MB.

    Does the case have good airflow?
  2. you're probably using the wrong version of prime95.

    use version 26.6 here:

    run small fft test and give us an update

    To my eyes and experience, Prime95 has outlived it's usefulness. Here's my thinking based upon experiences over last few years.

    1. You can use P95 (never versions) and when modern instruction sets are used, the associated voltage bump can can result in extreme temps and, as has been reported, even damage the CPU.

    2. You can use the older 26.6 and prior versions if you are anxious to prove to yourself that your system is stable ... as long as no modern instruction sets are present ... the ones that are part of those applications that are likely to really push ya CPU. So its kinda like testing the off road capability of your new 4WD SUV by driving down the highway in 2 WD ... all it proves is ya car can drive down the highway, tells you nothing about it's off road capabilities.

    So yes you can use it ... but what's the point ?

    Another thing to consider is .. would you test drive that SUVs towing ability to tow your 14' boat trailer by towing the Space Shuttle up the Rockies ? If ya built the PC to run programs or to get on web site overclocking boards for having the highest OC w/ P95, then it's a necessary tool. ? but if ya built the PC to run applications an games, not so much... also why set your max OC by using thermal limits that are only going to be reached by synthetic applications ... ones which your PC will never see again ?

    Under this scenario, and assuming you picked 80C as your max allowable CPU temps, what OC ya wanna pick ?

    4.7 GHz ... 77C under RoG Real Bench
    4.7 GHz ... 84C under P95

    4.6 GHz ... 70C under RoG Real Bench
    4.6 GHz ... 77C under P95

    I'm gonna stick w/ 4.7 Ghz because RB puts a far far greater load than my CPU will ever see in its lifetime. The fact that P95 breaks my 80C limit is of no concern because after I set the OC, I will never, ever use it again. I do use P95 for one thing ... its a great tool for setting thermal paste. I like to get it above my max stress test temp and cycle down to room temp a few times to get a good "paste set". P95 lets me do that quickly.

    If you can have "happy temps" with RoG Real Bench., you have seen temps that your PC will never, ever see again running any real application (one used to do actual productive work or entertain) that you can find.

    My highest core when I set up this box was 79C with RB @ 1.375v and the lowest was 70. It's a CAD workstation and does some other workstation type uses ... and after hours its a gaming box.... in 3 + years, it's no core has ever broken 68C.

    One other little tidbit. When I first tried RoG Real Bench, I used it in a PC I set up with P95 where it exceeded 24 hours stability test w/o crashing. It lasted just 50 minutes under the multitasking stress test in RB.

    Now if you want to use P95 for cooler testing, I have no issue with that. The older version is good for putting a stable load on the CPU. This makes it useful to compare the thermal transfer capability of various coolers, just not for setting safe OC limits nor testing stability... there are better tools for that.

    It has to be said that the H7 is not "all that great a cooler". Yes, absolutely, it's great cooler for the money ... but it's no Noc NH-D15.

    All that being said, you should not be seeing anywhere near those temps if you are stock speeds. May I suggest the following:

    1. Download RoG Real Bench and HWiNFO64

    2. When you open Real Bench, move both windows to left side of screen. Open HWiNFO64, run "sensors only", you will get a pop up asking whether to disable reading any chips, click "Disable this sensor". Move the HWiNFO64 window to upper right hand corner of screen. Stretch bottom of window to full screen height.

    3. Go to Real Bench, select Benchmark Tab and Check only the last box. Start the benchmark and don't touch mouse till finished. Observe voltages and temps and shut down if ya see anything ya don't like.

    4. Now try checking all 4 boxes and run again NOTE: During the 3rd test Open CL will send AVX instructions to CPU; pay close attention to Vcores as they may spike.

    5. Come back and report

    Ambient = Room Temperature
    Idle Core Temps Before Test on Each Core = i.e. 25, 26, 24, 22
    Average Core Temps for Each Core During Test = i.e. 59.6, 58.2, 52.7, 49.4
    Max Core Temps During Test on Each Core = i.e. 65, 62, 59, 54
    Settings you input in BIOS for VCore say 1.20v
    Actual Max Voltage Readings in HWiNFO64 for VCore

    Oh yes, and if you have changed any BIOS settings for your OC

    This will provide a more realistic set of temps for analysis based upon any application that you might actually use ... max gaming temps will be 5 - 10C lower
