High temperatures on my 8700k

[coonbro]

I have a Corsair H80i v2 with a broken screw but looks quite tight, thought

pretty much sums that up for me

you want the prefect mating of the coolers cold plate to the chip lid - why you should check to see if any lapping needed from a uneven cold plate or chip lid - too tight/ too loose . tightened down uneven or crooked too much or too little paste old paste or fresh can all be a factor in great cooling poor cooling or just so, so cooling . with 2 screws missing I cant see any of that in the good to great cooling or even close to any kind of proper efficient mounting .

theres more to just slapping any cooler on just any old way and matter of fact to me its the hardest part of a build to get that perfect as I can - folks would be supprised how even a low buck or even a stock cooler could do if the time was taken to do it correctly and insure the mating of the chip lid to the cold plate . also it can take 24 hrs +/- fopr the paste to set / cure and temps could go down more. I just dot see from 80c

also if you go to corsairs forum and look at these coolers like yours you see a lot doing like yours is anyway . could be a pump flow issue if I thought the cold plate was right and not missing screws even bad voltage a few claim ?

but seeing right off the mounting is missing parts that would be step 1

good luck

sad thing is unless one of these would work no V2 parts ...hmmmm,,,,,,,,

then you know that part of things is right

The same here.

Do you mind to share your temps when Gaming and full load?

After about 15 minutes of full load under OCCT, my hottest core maxes out at 77°C, my coldest core hits 70°C.(The processor is not yet delidded.) Also, my fan curve is optimized for silence over temperature. So my fans only hit 50%@70°C and don't go any higher.

After about a hour of FarCry 5 the hottest core is 71°C, the coldest is 67°C.

Room's temp was 26c, in full load the Vcore was min 1.248V and max 1.26V., what is your Vcore in full load?

Note: just in case you are curious about my temps been that high even i am using a Waterchiller i can explain it.

 

[newtekie1]

My vcore at full load is pretty stable at 1.248v, but every once in a while it will jump to 1.264 for a second then drop back down to 1.248v. Room temp is about 21°C.

That's Exactly what my Vcore does.

The only thing here is that your Room temp is lower than mine.

Those Noctua NF-A14 you have performance pretty good, i have some of them somewhere lying around, i have 5 NF-F12 in my main Machine.

1. I have yet to see a CLC that performs equal to any comparably priced air cooler. temps are comparable but the CLcs are as much as 12 times as loud. Simple put, CPCs have no raison d'être other than being able to tell ya friends ya have water cooling.

2. While automatic overlcocking utilities have vastly improved in recent years, remeber that these are developed so that all settings are high enough to work on most (say 98th percentile) CPUs.... chances are 1 in 2 that your CPU is betetr than all but 2% of CPus out there, so these settings are most likely higher than what may be accomplshed manuall. However, since it's unstable at settings you have tried, it would seem 4.9 or 5.0 may not be in the cards. So while usiing the utility is great time save to "get you in the ballpark so to speak ... you should think of it as a starting point only.

3. Synthetic stress testing utilities have lost their raison d'être . It's like testing your car's ability to tow your jetski the 12 miles to the shore line by towing a 12,000 pound load up and over the rocky mountains.

a) I have had 24 hour stable P95s OCs fail in a multitasking benchmark like RoG Real Bench in under an hour.

b) Did ya build ya box to run stress testing utilities or to run games ? After yoiu prove ya system stable under P95, when is the next timew it will see a load like that again ? ...never. So what's the point poc climbing the Rocky Mountains when all ya need to do is get ya JetSki to the beach ? You wil put far greater strain on your engine, and it will run that much hotter than it would otherwise. Even in Real Bench when you see 75 - 78 in stress testing, in gaming it will only be 58 - 65. In addition, 1.38v will come very close to breaking 1.50 when AVX or other modern instruction sets are present.

4. You can protect the CPU from any damage by using an older version of P95 that lacks these modern instruction sets, but then what have you prved ? ... that your CPU is stable ony oif these modern instruction sets are not resent. kinda like testing your SUVs 4 WD capability by driving down a highway in Florida. In short, if ya test ya CPU with a applicatoin based utility, you prove the CPUs stability in afar greater range of usages than if using a synthetic utility. You will also avoid unrealistic situations because your are limiting your OC bu 0.1 or 0.2 maybe even 0.3 GHz because of an "imaginary" condition that thesystem will never see ever gain. Nothing you are likely be doing on your PC will ever impose a multitasking load greate than RoG Real Bench (which includes h264 + a mutitasking load).

5. Note that lapping voids the warranty on many coolers. While potentially useful on inexpensive blocks with poor quality control, CPUs do not have a flat surface (slightly curved) and cooler manufacturer's .. ... concave = bad / flat = neutral / convex = good

6. Yeah, the screw matters. The desired clamping force is 60 - 70 pounds ... even application of force should be insured before examining other causes.

Riiiggghhtt. "As much as" sounds like an isp. "As much as 100Mb/s" ( but actually not even close). 12 x .0001 =.0012x louder. i love your posts,

 

[newtekie1]

That's Exactly what my Vcore does.

The only thing here is that your Room temp is lower than mine.

Yeah, I took that screenshot this morning, and the house is cooler than it was last night, it was about 23°C in the room last night.

Did ya build ya box to run stress testing utilities or to run games ?

I built mine for video encoding, and the OP apparently build his for 3D rendering. So our PCs will see that kind of load again every day.

Just because you only use your PC for gaming doesn't mean everyone else does.

Tonight i will run a test for a hour playing DOOM, should i use OCCT, Real Temp or it doesn't matter?

 

[Oscargimenez]

Thanks Coonbro for the link. It's going to be expensive due to delivery in Europe but is the only good solution.
And thanks everyone for helping

Anyway I tried manual OC but not luck, I am noob.
Then I used EasyTune app OC and works fine for me 4,9 GHZ 1.305 v and not super high temps, so it's fine for now.
By the way, somehow the Temps are balanced in all cores and I didn't received the screw yet.

 

[erocker]

Get a replacement screw for your cooler. Mounting at 3 points instead of the intended 4 makes for uneven mounting pressure and high temps.

 

[Oscargimenez]

Yeah I did,

waiting for Corsair delivery/....

A little less voltage maybe? i am just saying

Speaking of mounting pressures there is no need to actually torque the cooler/block down, normally you can snug the block into place and that's enough. Too much pressure can cause things to go wrong such as the system dropping dual channel or even go as far as bending/crushing a few pins. I've had that happen to me before and had to fix those pins when I finally figured out what was going on.

I just snug the block in place and it works.

Note when I say snug I mean snugged, not torqued in place.
Install the screws, snug the block in place while keeping the mounting pressures even between the screws as you go and it should be OK once done.

Use "RealTempGT" exe ,your CPU have 6 cores.

true, thanks

I used Realtemp for the game temps.

I think it is ironic I used your delid tool and you don't even use it lol



fyi I never break 60 celsius at 5.1ghz on the 8700k. thank to your delid tool and some conductonaut on the IHS, and i used some noctua paste on top.

 

[trparky]

Mounting with only three screws can not only cause uneven pressure on the processor this causing higher temperatures but can also increase your chances of breaking the socket or even the processor itself.

Maybe depends on the Game but i did 2 runs and temps are a bit lower than yours.

1 hour of FIFA 2018 - hottest core 61c and coldest core 55c

1 hour of DOOM - hottest core 56c and coldest core 51c

I guess and as said before maybe some Games push the CPU harder than others, the room's temp was always 26.1c the only thing that it changed was the Water's temp, while playing FIFA it was 28.5c and while playing DOOM it dropped to 27.1c

 

[newtekie1]

Yeah, I originally bought it to delid a 4790K, when I built the 8700K system I didn't bother to delid it because temps were acceptable.

Your using a water chiller though, right? which one is it?

 

[FireFox]

I was waiting for that question.

That's right, i am using a Waterchiller Hailea Hc-250A

 

[jboydgolfer]

i was waiting for that question.

I'm on mobile a lot of the time, so I can't see system specs. However I do happen to know that Newtekie has the same CPU water cooler that I do, which happens to be an extremely capable system. when I saw your temperatures, i was thinking to myself "he's either got his air conditioning cranked ,or somethings a little off here". Then I took a look on my desktop ,and realized that you were running a chiller system, Which explained everything . Roughly 300W of cooling potential is nice to have, isn't it?

Newtekie's temps are right about where mine are, but i have an 8600k , gotten it to 5.3Ghz so far, but i dont OC much, just spent an afternoon screwing around

Now i want to explain something, that my CPU runs a bit cooler it doesn't have anything to do with the Waterchiller, i will explain you why.

That i have a Waterchiller doesn't means that every time i turn on my Rig I turn on the Waterchiller too, i have turned on the Waterchiller maybe 15 times since i bought it ( 3 years ago ) when the Waterchiller is off it's function is just be a big reservoir and when i turned on it starts automatically in idle mode, the Waterchiller won't never start to work or cool down the water if i don't set it to do it.

Case #1 Waterchiller off

It's not working at all

Case #2

Waterchiller on but it starts automatically in idle mode and it's not Working or cooling the water, the only thing that is doing is reading the water temp

If i had set it to work when running those test the temps would be way lower.
