i7 8700k Hyper 212x

[acid1011]

I am running i7-8700k with Asus Rog Strix z370-f motherboard cooled by Coolermaster Hyper 212x with a push pull dual fan setup.
The following temps were achieved with AIDA x64 Extreme ***Stress CPU*** and ***Stress FPU*** test.All the fans of my case were running at 100%.
I had an xmp profile enabled which boost the core clocks to 4.3 i guess.

 

What i wanna know is :

 

*If i want to keep using these clock settings,are the temps safe?

*Should i upgrade my CPU cooler? 

*Will real life scenarios (Gaming Mostly) ever reach these kind of temps? (cause i read FPU test pushes the temps higher than most other apps)

That isn't even very high clock speeds

 

Likely wouldn't suggest overclocking past 1.25V, should be able to do 4500mhz all core there maybe

i'm not going to do manual overclocking any time soon. If i can run at 4.3 for now with this cooler that would be adequate for me for now.

Your temps are fine. Games usually don't push your cpu harder but gaming usually stresses your gpu as well which can put out more heat into the case and raise cpu temps. 

If you want something quieter or to push a higher oc, a better cooler can help. That being said, you can probably do better than 4.3ghz with your current cooling.

My line for max temperature is 75C, so try use less voltage.

How much would u say is adequate for 4.3 GHz stable?

Depends on your specific cpu, you would have to test out a lot of voltages to find the answer.

I would say 80.

It depends on your chip's ability, but you cant hurt a chip with low voltage. Start from 1.25V and drop it 0.01V a time, till it crashes in 5 minutes AIDA64 FPU stress test. When it does, call the last stable voltage + 0.04V the final stable voltage.

Thank you, ill let u know how it goes

And then also test some games and things. Sometimes an OC is stress test stable but not for other loads

I've got a Hyper 212 Evo on my 8700K (I was using it with an R5-1600X  before, so it used to be all I needed), and the best I can do is 4.7 GHz on all cores at 1.25v. Aida64 pushes me to 89 C, and this is literally only MCE with manual voltage. Gaming is fine and never goes past the mid 70s at the worst and usually sits in the 60s, but my video rendering workloads make it hit ~80 C.

 

That said, not all silicon is made equal so some might not even get what I have. The only reason I keep it on is because my actual workloads never push it past about 75-80.

 

So yeah. An 8700K needs better cooling for actual overclocking.

[acid1011]

I changed "SVID Behavior"from auto to best case scenario and that dropped my voltages and Temps SIGNIFICANTLY

How do i get the voltage at the value i want? 
I have set it to "manual" at 1.220 and the turbo ratio to 4.3. AIDA stress test seems to push the voltage to 1.244 constantly

 

okay wait a minute. CORE VID and Actual core voltage are not the same, are they?????

anything below 85-90 full load is safe, unlikely to reach these temps on actual game, u could test ur gaming load with ACO, kingdom come or ashes of benchmark. it's usually between 60-70% usage for me. you can try 4.5 with 1.25v, maybe even 4.6 depending on ur luck.

vid is how much the vrm is outputting, not what the cpu gets (vcore on cpu-z), but at the end of the day check temps. (ie my vid is 1.37, actual vcore is 1.33)

I got 4.8 stable at 1.2v and I don't think I have a particularly good chip so op should be ok with 4.7 at 1.2 right ?

Check LLC settings

i can run at 1.08V @4.5 GHz all core. Should i Decrease the voltage further??

Anything under 1.4V is likely safe, but it sounds like a pretty good chip if you can run your voltage that low.

i ran aida 64 with FPU and CPU test for about 20 minutes.
is that enough to indicate stability?
should i go for longer burn ins?
Or any other tests like prime95?

Probably not needed because those are already unrealistic workloads, if you're just gaming most of the time you should be fine.

Wow Nice!!!!! may be ill push for higher clocks once i get a better cooler

You'd be likely better off delidding it to get better temps rather than slapping a larger cooler off it.

that would be a little too extreme for me :V i need the warranty for peace of mind  and 4.5 GHz is more than enough for me at the moment

Those are completely expected temps with that CPU and that cooler. As for the safety/longevity of the chip at that temperature, I would not worry until you cross the 85c threshold. Is lower better? Of course! HOWEVER, unless you are in a very small form factor case, you won't reach that while gaming. Secondly, voltage tends to be the number one detractor from CPU life. If your voltages are in check, you're more or less good to go. Again, Intel rates their chips to 100c (that's the BOILING POINT of water)! 15c of buffer is generally sufficient. That all being said, I would not advise pushing your chip to a higher speed or voltage unless you invested in a more effective cooler.

 

I hope that helps!

im currently at 4.5 GHz with 1.084 volts.
I can run AIDA64 with both CPU and FPU stress test ticked but if i run ONLY the FPU test then i get a bsod. 
Is the FPU test alone necessary?
Again, i can run aida when both stress cpu and stress FPU options are enabled
