Cpu extreme high temp :( i9 9900k

Gabriel Trocan · 7 Feb 2020 at 15:25

Hi guys,
I am having trouble overclocking my i9 9900k. I also have an aorus ultra mobo and nh-d15 cooler.
No matter what I do my cpu is either unstable and any test crashes or the temps gets above 90 in a matter of seconds in realbench for ex. The cinebench r15 is the only stress test I can pass.
Is it a bad cpu? Or it can be smthn else.

What clock speed? What voltage? What settings for adaptive voltage?

Try offering more information about what you're doing, what you have tried, etc. Have you had a stable clock speed and you can't bring it to the next multiplier up?

Start with your specs including memory and all overclock/memory adjustments.

Proc: i9 9900k
Mobo: z390 aorus ultra
Ram: corsair vengeance pro rgb 32gb 3200
Cooler: nh-d15

Clock ratio 50, avx auto (no chance with any avx setting but this), enhanced multi core perf DISABLED, cpu vcore 1.32v,
Vcore loadline turbo, C states disabled.

From here I only changed the voltage but what is under 1.32 in not stable and what is above ..like I said..temps go crazy. Like 90-95c in 15 seconds in aida.

Bad mount on the cooler? I assume you have re-mounted?

What exactly are you doing when you run into problems?

If you're trying to run a Prime 95 torture test or some extreme synthetic benchmark you'll probably run into issues. If all you do is game tests like that aren't realistic for your usage, in fact they probably aren't even with most productivity work.

It's also worth making sure the HSF is mounted properly and you've applied enough thermal paste as mentioned by @Vince. Additionally, how is the airflow in your case? What are your ambient temperatures?

I use realbench (heard is more closed to reality) but also in aida64 I get those temps. It is true that I am havin NO issues in games, but I see people getting their i9 stable WITH avx 0 and temps under 85 and I assume smthn is wrong with my system.
Where can I check the ambient temp? In bios it says: system temp 32.
the case is a nzxt h510i. Not the best airflow, i guess

You would imagine that a noctua d15 would be able to keep it under 90 @ 1.32 running non AVX wouldn't you? I mean I don't and have never owned a 9900k but that seems toasty!!

On youtube many are using this cooler with i9 and seems ok. The cooler only gets worm (not hot) only when the temp is above 95c. It is very big and it spreads the head fast, BUT the i9 is getting hot inside, the heat never reachs the ihs so that the cooler can disipate it. ...that s from what I heard anyway

I've heard from a few people that the D15 struggles to keep an OC'd 9900K under control funnily enough, but usually it's when people are using insane synthetic tests that really aren't realistic to their workloads.

It's one of the few cases where a decent AiO might actually be better than high end air, and trust me I'm a big advocate of high end air over CLC's etc.

I will try a kraken x62 tomorrow and see if there are any changes. Many people on utube manage to keep the cpu under 75 with this cooler, but sure..who knows what golden cpu they might have. I do have the delidding option it only costs 30€ and I heard it can lower temps

It's all about the delid with the K isn't it? I take it you are not up for doing that and getting busy with the liquid metal? My Intel game is weak last intel chip I had was a q6600. I prioritise workstation and VM over gaming so my rig is focused there but games well enough for me to be happy.

Problem is, if it is bad contact between the ihs and core then it doesn't matter that much what you are throwing at it, a lemon is a lemon, if the heat isn't getting from the Core to the IHS and then to the cooler it's always going to be hot. I guess that is why the market was all about the delided and binned chips.

I also have the option of returning it to the store and get another one, but I was hoping to get in touch with someone that has the same cpu and tell me how are his temps.
I know i9 is hot but I donno how hot so I can t tell if mine is bad or..it s normal.
I know it is syn test and no game will ever do that to the cpu but I am worried that even so..95c and rising (no overclocking) is too high

I'm inclined to agree.

If you (OP) can replace the chip you have for another I would do so before considering a delid option, as you'll lose your warranty.

It would help to know your ambient temperatures though, you still haven't answered in regard to them.

I did ..35-38 but I m not sure i am looking in the right place. Bios - system temp. Is that ok? I don t think that is so important in my case. In aida64 stress test, the temp gets to 95 in seconds..so...don t think the ambient temp matters in that regard, i could be wrong though.
I won t loose the warranty (the guy assured me) it is impossible to tell it was delided. At least that s what he said

Ambient temperature means the temperature of your room

Ohh I thought inside the case. It is 24 in the room maybe 25

If you sent a de-lidded chip back to Intel should it die I'd be very surprised if they were unaware, and I'd be even more surprised if it didn't negatively effect your warranty.

Official response from an Intel rep on the subject of delidding.

I'd not take the chance personally.

Read my above response though, I edited it after glancing back over the thread.

To reiterate:

The temp in the room is 24-25 (i thought you meant case temp).
I am using a nzxt h510i case. It has to fans, one in the back of the case and the other above.
I bought the cpu from a retail store not intel, so..they won t figure it out. But I am not planning to return it if I delid it. Would be waste of money.

Normal enough.

Your case is decent, I'm guessing your fans are a front intake and rear exhaust? Everything is more or less within expectations really that being the case.

I would consider a return on your 9900K before you think about a delid, give a second chip a chance if it's that important you get stable for synthetics, but as I mentioned earlier if all you do is game and you're not having problems there I'd not be massively concerned. Of course, there's the Kraken you mentioned earlier to test also, so there might be a fix before you need to go to any extremes regardless.

The 9900K is technically the best gaming chip, but good lord the potential PITA is more than I'd want to deal with when trying to OC it, I feel for you bud.

Both fans are exhaust. Yes I will see how it goes with the aio.
It is true ..in game everything s fine but still, I paied for it and I want to be as good as possible, or at least not a faulty one

Gray2233 said:
Your fans should function as a front intake and a rear exhaust, if the front is an exhaust it'll have a negative impact on your temps, although I doubt it'd be quite so major as you've explained.

No. There is no intake. The front panel is closed. Only two exhaust in the rear. Look at the photos

But then again those are fine tunning. I think I have a bigger issue here. Or...most of i9 are the same. That s what I m looking for ..someone with i9

Try it with the case open, just to prove it's not airflow related.

I did..

Haver not read complete thread for now (headache) but you days it is 90C but the cooler is warm not hot, in that case its not transferring to it fully, you need to look at the mounting/Delid (if it was done and not done correctly).

Did that several times. No issue there. After 95 it starts to gets warm. I think the cooler is doing a good job dissipating the heat, but there is not much heat getting to the ihs. That is way delidding is a good ideea. so what about ur temps?

You don’t need old versions of p95. Latest version has bug fixes and you can disable AVX via checkboxes.

If you’re looking at an aio, I strongly suggest arctic freezer ii 360. It’s great performing, non asetek and cheap. The vrm fan actually helps out also.

De lidding a 9900k is useless unless you’re going to do direct die. Then it has merit.

I’ve owned a 9900k since launch and have it well tuned so not speaking hypotheticals.

What about kf? Does it perform better?
