CPU temperatures i9-10850K + Kraken x73, Am I doing it right?

[Cruz0e]

I am using i9-10850k (not overclocked yet), cooling cpu with Kraken x73 and after 5-6 minute stress test (with program prime95) on all 10 cores 100% usage, my CPU temperature suddenly jumps from like a nice average of 70 up to an average 95 (90-99) celsius. Is this normal?

Is this test okay? normal? is this how it should behave? I don't know I never did these tests before:D 

You see I started stress test at 9:52, then I stopped at 10:04 (I did a more bit extra test after too thats why those jumps)

So is this normal that the temp is okay for 5 minutes stays around 70 celsius, then suddenly jumps up (I guess when the water is heat up in the AIO), to 90-99 , then the temp doesnt go lower even if the CPU throttled back to 3.6.3.8 GHz?

what stress test? does it use AVX2?

I don't know its a program called prime95, I found on a website which claimed it is good for CPU stress test.

I just googled and it says:

So I guess the answer is yes to your question:) but im not sure im new to this test thing:D

[Cruz0e]

Now that you asked I actually 'read' the screen, before I just pressed 'OK' without reading and started the test, now I see I was running the torture test probably  
 

[Cruz0e]

Now this rises a new question while still waiting for an answer if my results are ok, but the new question is what other tests should I run? Should I overclock? Etc?

This does not look normal. Your temps shoot up at the same time as the core clocks goes down. You should do the same test again but also monitor core voltages. 
 

Is your bios up to date?

I literally just built the PC, I dont know if my BIOS is up to date probably not, let me check , I have also the voltages too logged, I logged everything I just didnt put it on the chart, the voltage was pretty much between 1.38 and 1.4

I see on the website there is a newer one dated 2020-08-04, let me update this.

Wow. You do a "blend" of all tests and you are wondering why your temperature jumps? Because the test switches to something more torturing! Don't be fooled, you PC is fine.

Thanks, thats what I thought, and that's why I am here and asking, I told I am new to this testing/overclocking thing, I just wanted to do some test before I try think about overclocking.

I built a few PCs in the past, but the most modern one was I did was an i5 (with 650Ti then later upgraded to 1060, but I didn't do a big overclocking/testing on that).

So I built some PC already in past for myself and my family (starting with 80286, then a 486DX, then a pentium, then two x i5 (one for me one for my brother) and now this i9 10th gen. But I never did more than a simple benchmark test, I never overclocked "hard", or did stress test before, so I posted this just to double check. 

/Anyway I now updated the bios too to the 03/08/2020 dated one./

So do you recommend do any other test so any more test now ? or I should wait for my new GPU arriving (3080) and test CPU together with that again?

By the way this is the build:

some update, I realized after bios upgrade that my XMP profile was resetted too, or for some reason i did not have it turned on, so I fixed that, now its set to 3200MHz
(though HW info shows 1600 only I gues its because it shows 1 channel, and then 2x1600=3200 on the dual channel)
after that I did change 2 settings one, the boost instead of auto I set to 50 and also instead of dynamic set to fix, so all core now run 50x100=5000MHz

and then I run a 15minute (I stopped at 10 minute because it was stable for 3-4 minute with no change) CineBench20 test and during that I monitored and logged the temperatures, the only thing changed in about 6 minutes the liquid temp went from 30 to 35-36 (for some reason HWinfo shows 30.8 in the log everywhere, but NZXT Cam showed me real time changing it from 30 to 35-36), but then everything was stable for 4-5 minutes so I stopped it

cpu was stable at 85-86C, liquid temp was 35-36, core clock was set to 5GHz, fans went a bit loud (like if some1 was hoovering next door)

[Cruz0e]

I also reduced voltage now from the default 1.338 to 1.3, the same (above) Cinebench test run same way but now 80 celsius instead of 85, tomorrow I try go down more maybe 1.28 or something, see if its stable...

[Cruz0e]

Update: Reduced voltage of CPU to 1.28 now looks stable, even Prime95's "Small FFTS test" (which caused earlier super hot 90-99celsius CPU temp and throttle) right away at run, was now running for 4-5 minutes stable 86 degree, all other test Cinebench, Aida, CPU-Z stress tests were running nicely with good 65-70-75 celsius temps.

I have the same CPU as you with a less good cooler, and can't run 5 GHZ all cores sync stable unless going for like 1.45vcore.

 

I guess I have a bad silicon chip. What I would like to point out to you is I could run all benchmarks with no problem, and prime95 / occt / realbench stress tests as well for ~10-15 min.

 

But soon or later, OCCT / Prime95 / would find errors in hash results / unstability

 

For me it was around 15 mins so clearly the setup wasn't stable even if sending as much voltage as I could / would.

 

I am just saying the fact you run a stress test for 5 min doesn't mean anything and if temps went 86 degree in only 5 min theres high chance most if not all your stress tests will crash and/or your cpu overheats after 15 min / 1 hour  / 4 hours / 8 hours etc..

 

I call an overclock "stable" when it passes 24 hours stress tests. Best is to test more than 1 stress test.

 

Hope that helps ! Btw, mine runs @ 1.3vcore / 1.33vcore stock when on load !

Yes actually last night my friend was helping me (we had a 'video' conference on my phone) with the bios settings, and he was saying looks like I was lucky on the silicon Lottery  Maybe I need to run longer tests, you are right on that. But stability also depends on the motherboard, mine is a medium one (in pricing) I chose one using a rating I found on reddit. only a couple of boards was rated S+ (it was rated by the capacitors, and stuff, and stability, built quality, heat dissipation, etc. so I went with MSI MEG Unify, the other option was Asus Maximus Hero or the way more expensive extreme and stuff...

My was to just do a quick test now, and do longer tests few weeks later, when my 3080 arrives and I install it, because right now I got my old 1060 in the PC
