HI. I have 8700K on stock with mobo Asus Z370 Pro Gaming + case Fractal Design R5. Cpu temps on games are fine 70C+.

When i run Asus Real Bench it skyrockets in stress test to 95C, and i am stopping test. Any ideas why it causing this?
My cpu cooler is Cryorig M9i.Cpu is not overclocked.

XMP profile enabled in bios on memory 3000mhz. UEFI STOCK bios. cpu clocks during test 4700mhz so i guess is oc on auto?
 
cooler fitted correctly, used a sensible amount of thermal paste?
fan profile running correctly? enough case airflow?
but i suspect is because you're running a cheap cooler on a high end chip.
8700k can get toasty. their true tdp is probably ~120w rather than the intel quoted 95w
 
I tried Unigine Heaven and its 50-65c max on some spots. I compared this with other the same. I dont know why only in this syntetics are very high temps
 
And Unigine Heaven is a GPU benchmark, doesn't stress the CPU much. Heaven should not be making CPU 65C nor should Realbench be making it 95C (although latter will/should be 5-10C hotter than something like Cinebench).

So you are getting higher temps all around, not just in Realbench, just that it's more obvious there. If you played a game that stressed the CPU more, you'd probably be seeing 80s.

You'll need to refit the cooler (and repaste), and check that the fan is reaching max. And if that doesn't help, then a better cooler is needed.
 
That cooler is only rated for 120W TDP so that is likely to be the problem when under stress test. A higher end cooler such as the R1 Universal or Noctua D15 etc would do a better job. As long as it isn't overheating when gaming though, then you are fine.
 
Hey really appreciate it for help. I compare temps with other user with 8700K in youtube in Unigine Heaven. He clocks are 4700mhz the same. And he heave identical temps in Heaven , max 65C in some spots. In Crysis 3 i have 60-72c temps in first level.
3dmark 70-80C.
What you think. Should i stay with my current cooler and uefi settings or change something? Thank you.


3dmark physic test looped 70-80C.
Unigine Heave 50-65C max on some spots.
Crysis 3 first level 60-72C



Today after work i will try GTA V.

You should be fine with that cooler as long as you avoid using the Asus realbench stress test. If you are just gaming and getting temps in the 70's then that is fine.
 
Ok i tested GTA V. Temps in city 60-75C. Few times spike to 80C. Thats all. On grass areas 55C. But i noted weird stuttering that i hadnt on 6700k previously.
Maybe 1 time of 30 minutes of play i have fps drop for 1 second and back again.
For example: 144fps drop to 100 fps and again to 144fps.
Is this related to game or maybe hardware? I am playing on window mode.
Maybe should i play on full screen?

I tried firestrike 3dmark or doom and i dont have that drops.
Ah and i am on newest nvidia drivers

It's a part of the game, as long as it happens in specific areas - for example when driving/flying north, out of the city, or in the south-eastern part of the city where the train tracks and lots of fences are. Fullscreen may or may not help, but can introduce tearing on some monitors whereas windowed mode usually helps a lot with that. Test and see. You can also disable "Fullscreen Optimization" in the game .exe properties if you encounter issues. It helped me get rid of tearing in Borderless Window mode (after Windows 10 introduced it and put it on default enabled, where there was no tearing before).

Yeah, Doom is (or should be) smooth as butter if all hardware and software is fine.

Regarding temps - GTA and Doom use about four cores, give or take. You're going to be hitting 90s with games that use more, or if you stream whilst gaming GTA/Doom, for example. It isn't ideal. 75C is a good max figure except for processes running AVX instructions which make temps higher, but even 80C would be "ok" if it was max. Thing is it's not max, so unless you stick to four core games and/or no streaming etc, I would be looking at doing something about it. Or keep a very close eye on temps constantly.

You could try Cinebench R15 which uses all cores and see what max temp you get.
 
It's not stock if it's running 4700 in realbench. You must have MCE enabled, you probably answered yes when the bios asked you after enabling XMP. So you are running higher than stock clocks when multiple cores are loaded, but more importantly MCE cranks the voltage to pretty high levels which is probably what's affecting your temps.

4700 is the max single core turbo at stock, you will almost never see this speed in Windows because there is almost always more than one core in use. This is another sign that you have MCE enabled.

Either turn MCE off (the real world differences are pretty negligible), or manually tune your voltages (vcore, vccio, vccsa to start with).
