i7-8700k runs insanely hot even at stock speeds ?

[Krit]

My 8700k doesn't go above 48c playing GTA V. Not delidded.

What are Game settings and cpu cooler ?

@Vayra86
Yeah, I read. Do you?

This is what he said:
"my stock i7-8700k cpu runs very hot even at stock speeds and voltages"

Which part of STOCK is not understandable?

 

[Krit]

i7-8700k @ 1.230v, 4.8GHz all cores, 4.9GHz dual cores, 5.0GHz single core.

 

[de.das.dude]

well, seems like all the shintel memes do have basis over at r/ayymd

 

[Krit]

drade way you are not showing your intel burn test results ? Or just it's too hot to show.

 

[EarthDog]

Lol, relax....if the guy cant simply google and dl it, its going to take time to figure out how to run it.

Better run Intel Burn Test like i did. These comparison will be better because of load on cpu is exactly the same.

We know the point of it all... its just funny watching laurel and hardy go back and forth trying to accomplish this...

So why does that new screenshot show you average in the 80 degree range, when you showed an earlier that was low 60s?

Because the former pic was unbelievably impressive. At least to me.

Becouse CPU is overclocked to 1.230v @ 4.8GHz on all cores, 4.9GHz on dual cores and 5.0GHz on single core. That's a 500MHz difference on all cores and 300MHz on single core.

Err.. sorry. Not paying enough attention. I thought you were just going with stock. I heard it runs fairly hot even at those speeds. It's hard enough to bring down my Kaby Lake to under 60.

Hi guys!

My problem is when i run intel burn test my stock i7-8700k cpu runs very hot even at stock speeds and voltages. Only think that is overclocked is ram 3333MHz @ 1.35V but thats all. Cooler is premium noctua NH-D15S and case ventilation is decent with 3 case fans. So is these temps to hot or it's normal ?

Have you actually read the description of IntelBurnTest? Have you understood what it does?

 

[EarthDog]

I'd rather stick a pitchfork in my face than see this thread go past 115 posts.

The blind will lead the blind to wherever they end up. Good luck my man. Unsub'd.

 

[ASOT]

I think is better to close this thread for further reply ..

I'm still here man. I haven't had time to run the tests. I plan to this weekend .

OK, I got it.

So after doing the intel burn test per your recommendation my temps were quite higher than I had anticipated. I did not realize 100% CPU usage for ~10 minutes like that would cause my temps to hit high 60's and at times low 70's. I may have to check how the thermal paste on the CPU. I am shocked due to effective airflow usage within my case environment.

being shocked at normality just means your perceptions must be bit skewed..

I am shocked because I come from the liquid cooling realm. I anticipated my case and the Noctua D15s, which has high reputation due to cooling performance, longevity, and its six year warranty, would cool more effectively.

Lol, it isnt the thrermal paste... and you also need to give it several more mins to max temps. Water tales a bit longer even. Warranty has nothing to do with performance... lol




So, temps normal... we finally good?????? What a thread, lol...this was called from post 8 with first voltages, 58 after he lowered the voltages!!

 

[Vlada011]

Why is voltage so high for 4.3GHz...or even Max Turbo.
i7-8700K Turbo is 4.7GHz... On default settings CPU should boost with all cores on 4.7GHz only on default voltage. In previous years Turbo vas 100% stable on default voltage.

From my perspective is negative if BIOS is not optimized with Turbo Enabled on default.
I don't know how much is default voltage exactly but I suppose 1.100-1.150V.
If 4.7GHz is Turbo for All Cores than Out of box voltage should be 0.xxx idle 800MHz and 1.100V full load on 4700MHz.
I suppose no matter on thermal paste CPU Temps should not be over 75C in Intel Burn Test.
But so high temps are expected, these new models are tested only with Real Bench, AIDA64, Intel Xtreme Utility...
Silicon Lottery and others sell binned chips stable on these tests, they are not even close to pass Prime95 or Intel Burn on such high clocks.
That's very old test not optimized for new processors.

But on default settings shouldn't be over 70C.
Mine i7-5820K on 4.0GHz Once I tried Prime95, I was ready to disable immediately, but when I saw 60-65C I continue to test.
Voltage was default 1.150V and he didn't react so bad even on Prime95.

It's nothing strage, we remember i7-4770K 70-80C on default settings in Prime95.
Only voltage shouldn't be like this. If this is normal to voltage jump so high that's very bad.
I expected 1.250-1.300V if customers OC to 5.0GHz in Adaptive Mode and voltage to incrase in full load and drop on 0.xxx in idle.

 

[EarthDog]

Its over vlada... already resolved issues dozens of posts ago.

 

[Vlada011]

OK, I look fist and last posts and had different opinion.
I was curios to see how i7-8700K behave.

 

[trog100]

folks should try running the IntelProcessor Diagnostic Tool 64bit..

it get a pass even if the cpu is at 99 C..

I think these temps are ok what is your temperature on hottest core and how high is your CPU core voltage during the test ? At what speed CPU and Case fans are spinning ?
