i9 9900k Temperature worryingly high

[boostang99]

Hi guys,

I am new here and this is my first post so please pardon if I did not do this correctly. I have just built my first pc and am a little worried about the temps. I talked with intel support and they don't feel there is a whole lot to worry about but it just doesn't seem right. My build is the following:

Gamerstorm Quadstellar case (case does not breathe well so I leave glass panels off during gaming)

9 thermaltake ring plus fans

aorus z390 master mobo ( bios flashed to most recent to support 9th gen.)

corsair rgb vengeance 3000hz ram 32gb total (cpu clocked at 3000hz memory as well)

i9 9900k ( stock speeds and voltage except memory clock)

gigabyte rtx2080ti waterforce extreme wb

thermaltake d5 pump set to max flow

thermaltake c360 radiator and xspc 240mm thin radiator

thermaltake pacific cpu water block

 

The issue is that at idle my temps are fine (30 degrees) but as soon as I play battlefield v for any amount of time (hour or so) my temps seem to have a couple really brief spikes to 79 degrees or so. If i run cinebench r20 i will get temp spikes up to 84. and when I ran prime95 I got an instant temp of 95 (small fft). I have pulled the waterblock off and re-applied thermal paste to make sure this was not the issue (NT-H1) and also checked that the backplate was correctly attached. The gpu stays very cool and never gets over 60 degrees. These are on the same loop. With no OC and just a memory clock I am very surprised at how hot this setup is reaching. Any insight would be greatly appreciated. I know this CPU runs hot but don't feel this should be this hot. Thank you for all your help! 

 

Only video or picture I could find on my pc to show the setup =P

Your temps are perfectly fine.

79C is safe. 84C is acceptable for Cinebench, which is a short burst anyways. Prime95 is a stress test and has no indication of real-world temperatures from real-world tasks (95C is still under the thermal thresh-hold of the CPU anyways, so you're safe).

 

If you wanted to lower temps, you'd want to put the CPU and GPU on separate loops. Otherwise, you can increase fan curves and remove the CPU memory clock boost and see what happens.

It seams like your CPU Block  is not making good thermal connection with the CPU due to either not being seated well enough or nott enough or  to much thermal  past. That or somehow your CPU block is clogged with something.  There should be no reason that your temps are hitting above 75c on water at stock speeds.

the temps are not good for the amount of  Radiator @boostang99 has  I have 2  240mm rads in my system with a titan X and 5820K  OC to 4.4Ghz and dont even hit thoughs numbers   I idle at 27c  and at full load after playing Fallout 76 for hours I may see one of the cores hit 78 at most on my cpu. 

[boostang99]

I re-applied the thermal paste and only applied the pea method. When I pulled the block off the first time the distribution of the paste looked very well. I also checked for clogs and flushed the loop when I pulled the block off. The flow is very strong through the whole system and am not getting any high temps from the gpu that is cooled on the same loop. I can check the paste a 3rd time and re-flush the loop but everything was correct last time I did this for the same problems I am experiencing. It did not help any.

[boostang99]

Thank you all so much for your help. I keep scratching my head and digging into every article I can find about i9 temps.

 

Also all fan curves are set to 100% once the temps break 55 degrees and up to 75% at 45 degrees

Might be his case, lmao. 
iirc those things have horrible airflow/cooling

yes the case has horrible air flow.... So i keep the glass off during gaming to reduce the heat buildup.

[ELSknutson]

if your still having issues you may want to try Lapping your CPU

Never have done anything like that and honestly makes me a little nervous to try lol. Would I be best with trying to obtain a replacement cpu from intel? Could it be just manufactured poorly?

These temps with stock speeds on CPU is a mystery.  Get good contact with the HSF or block and don't put too much paste just stripe lines.  Then make you you fit the cooler and use screw to tighten it more without breaking the motherboard hehe.  Also what speed is your pump spinning at,  what are you fans spinning at ?

 

Even 60c at stock is high.  On full load on stock with liquid cooling you should get 30's and 40's on full load.  Aida64 stability test and what not.

yes also lapping a cpu is fairly straight forward but that being said if you can return your CPU for another one I would do that because once you lap it you will be unable to return it.

I have tightened the cooler with a screw driver already till its snug. The pump is spinning at 4800RPM and fans are running at 1400rpm under load

Thank you all again for taking the time on this situation

you notice that both your CPU and GPU have lower heat output than OP's right?

yes thats why @boostang99 temps worry me a bit considering mine are OC'ed and theirs are not.

high stock voltage and high factory turbo clocks of the 9900k means its heat output dont go up much when overclocked, let alone having more cores than your 5820k

Only thing I can think of is to temp remove the liquid cooling you got in there and put a HSF on it, a good one like noctua DH-15 or hyper evo 212.  I bet anything your problem will be solved once you put on the jumbo HSF.  Something is fishy about your loop my friend.

The most likely issue here is just underestimating the heat output/power draw of a 9900k to begin with, i'm gonna go with everything's working fine (if you don't run p95 fft on it), temps look fine, overclock likely not optimized, please don't go lapping your cpu just because someone is comparing a 5820k to a 9900k.

Thank you very much for your post. This is good news to hear. I see you are also running the i9 9900k. If you don't mind me asking, what temps are you seeing from cinebench r20 on stock clocks? or on a 4.9ghz clock. Mine hit 91c on 4.9. Thank you very much.

I have seen so much incorrect/bad information posted as fact lately it is kind of scary.

 

 

You're most likely fine @boostang99...even with the best watercooling setup, some stock 9900ks have trouble getting the heat out of the die to the IHS.

Thank you! I really appreciate it. The overclock at 4.9 was a junk oc by the way (too much voltage) so probably not the best to give any credit to the 91c temp. What should be the max temp to not go over on a overclock. intel support said as long as its under 100 im fine and wont hurt the life... Don't know how comfortable I am with that though lol.

cinebench isn't an avx app so it's hard to tell what stock clocks are, i have a 4.9-2avx oc at 1.26v~ that runs 4.9 on cinebench and 4.7 on prime/division 2 etc, power draw is about 135w and temps are like 60-70C (it's been awhile, i dont even have cinebench installed anymore), it only goes up to 85C on the 5.2-2avx oc. The 4.7 1.25v oc is very close to the minimal voltage required so temps are on the low side. There is a huge difference between running cinebench at 4.9 with and without an avx offset, 4.9 without avx offset is more like 5.1 cinebench in some cases (basically unnecessary, excess voltage)
