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

[EarthDog]

That's probably not true. All depends on games which ones you are playing settings etc.

Today i replaced thermal paste to Arctic Cooling MX-4 and it performs very close to Noctua nt-h1 there are maybe 1C difference at best. Cooler is mounted properly and fan direction is right case fans runs at 700 and 620 rpms.

You can increase fan speed as asot suggests... that may yield a couple degrees at best.

Mmm...
And.... what about this... :

The only way that gaming comparison can be valid is if verbatim runs the same one, same settings. As mentioned, some can be more stressful on a cpu than others. Hes a little warm, it can be anything...

Verbatim, what is your ambient temps? Those case fans are front/side = intake while top/rear = exhaust?

I think somewhere between ~ 20 - 25 degrees. One 120mm (700rpm) fan in front, One 140mm (620rpm) fan on top and one 120mm (700rpm) fan on exhaust.

 

[ASOT]

Man 1200 is not much,fans become noizy at 1400+

 

[Krit]

No 1000/1200rpm is noisy at least for me. PC is standing on table very close so i hear it very well.

 

[ASOT]

At that speed i doubt they move air they just spin

 

[StrayKAT]

I read above you had 61 degrees. How is this a bad thing? It's great. Almost unbelievably good, as I can only get it on 7700k with a lot of undervolting and AIO. What am I missing?

 

[EarthDog]

I mean.. are you worried about noise or temps more... something for you to decide.

Temps are just fine, so i would leave it as is.

First picture Noctua Chromax fans were running at 500rpm and have a max rpm of 1500.

If I go into the bios and use other temp monitoring programs stock idle temps reflect 32-35c.

Here is a picture of me in the lobby screen of PUBG. I game on a 2560x1440 screen with ultra settings. This was after ~25 minutes of gaming. My fans are set PWM and the RPMs were ~1100.

Note there are a few cores that hit 52c in the pic above (as I claimed earlier they do not exceed 52c). Let me clarify, when my fans are set at max RPM the temps are stable ~50c.

I hope this helps. The temperatures you are experiencing at stock speeds concern me. I have never experienced such temperatures myself. We are both utilizing the same high quality air cooler from Noctua.

P.S. I have been tinkering with the frequencies.

I see a core at 58C, one at 56C, and two at 54C. This guy has his fans turned down as well as testing in different games. Can't compare apples to playground balls because they are both red and round.

I do see what you mean by your clocks are high and voltage and still less... but getting there with an equal comparison is seemingly impossible.

 

[FR@NK]

I'm running at 83C!!!

Is this too hot?

I need to delid!@

drade what is your cpu freqency and voltage ? Stock or overclocked ? Your case fans runs at 1100rpms when runing pubg test for 25 minutes? I do not have this game pubg but i can test GTA V or Mafia III these are completely different games and mafia III has higest CPU usage by far! Maybe you can run Intel Burn Test exactly like me ? Right now we are comparing apples and oranges and what a point ?

Hey Verbatim,

Overclocked as of right now. PUBG is both CPU and GPU intensive like GTA V (never played Mafia series). I can run Intel Burn Test and post results. I am just trying to show what I am experiencing with the same cooler. I have no problem ramping up my fans to full RPM for the Intel Burn Test / Gaming.

 

[Krit]

Please run intel burn test at custom stress level "8000mb" for 5 times exactly like me. Show your CPU/RAM frequencies, Voltages, Fan speeds etc.

 

[P4-630]

Water cooling is probably going to be the future of cooling.

I don't think that...
Future chips should consume less and less power, air cooling should be sufficient.

Silly n00b question here, where is the best place to download this program? I have never heard nor used it before.

Who has i7-8700k cpu ? Please all run intel burn test like me to compare 1:1 Settings are fully stock cpu/voltages and custom stress level "8000 mb" "Times to run 5" for intel burn test.

I have tried to lowering these voltages but temperatures are almost the same... So it's isn't helping to me.

1. In your second set of screenshots here, your actual CPU vCore is *not* lower than it was earlier. The VID reads 100% the same and so do your temperatures - 1.256v

2. Do you know how MSI's UEFI is set up, what its functions do? If not, consult manual or guide before you start tweaking numbers. If the auto voltage is too high, I would start with a negative offset like others have said.

3. LLC - load line calibration. Look it up in your UEFI and see what its set at. It generally needs to be pretty agressive for best results in voltage stability. Wrong (too 'loose') LLC setting can also cause auto voltage settings to give higher voltages than needed, to counter vDroop.

4. Given the VID of 1.256v AND you running a Full IBT multiple runs, these temps are normal. I would not directly go for a remount of a look at your hardware. This fix is 100% all in your UEFI settings.

5. Idle temps are useless, nobody cares about that and neither should you. Gaming temps, also irrelevant, unless thats all you ever do but gaming is not a 'full load' on the CPU. But either way, for 4.3 Ghz all core boost, this vCore can go down and it should. Or, alternative: push up those turbo clocks and re-run IBT until you start bluescreening, so you actually get some advantage out of the vCore you got now. You know what temps it gives, and those are easily within spec.

6. - to almost everyone here: SOOO MANY ASSUMPTIONS. Can't we do better? @RejZoR the paste comments are getting old too and its evidently not the issue.

Last but not least, but I believe its been pointed out already: this CPUs Tjmax is 100C, and it will hard shut down at 105C. Safe 24/7 temps are generally and widely regarded as being between 80-88 C. Going into the 90's was and is never a great move, this is still exactly how it was all the way back to Sandy Bridge. Main reason not to pass into 90's on a prolonged stress test is because of seasonal changes; you don't want your OC to fall apart during summertime and over time, dust accumulation and other wear and tear will increase case temperatures as well (marginally, but still) It also accelerates chip degradation, but that is a very minor issue unless you intend to run this CPU for more than 6-7 years.

 

[Krit]

drade where are you disappeared ?

 

[RejZoR]

The paste thing is NOT getting old. If you want to transmit heat efficiently you don't smear and stack 10 layers of whatever in between CPU and heatsink. That's just the very basics of engineering.

Still massively offtopic to put the argument forward everywhere you go, especially when its A. not a solution to OP's problem and B. delidding voids warranty.

And, C.: its irrelevant because the CPU is running within spec.

If it's hot, it's clearly not running within specs, not with cooler like this guy has. It should be more than capable of keeping it cooled at clocks he's running. And don't tell me that if it's not throttling, then it's within specs. If that's the case, why this thread even exists then?

 

[Vayra86]

Really, man? And the CPU clock now determines the CPU temperature? What are you smoking? He's running a high vCore and fixed most of his problems when pushing 1.080v instead. Do you even read the topics you post in?

Tell me now, are those Nvidia cards capping at 83 C all over the world, also not running within spec?

 

[erocker]

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

Fact of the matter is, with these Coffee Lake chips, performance, heat, voltage, etc. varies A LOT. Some chips are hot, some not. The CPU is within spec.
