I7 9700k, 36°c-83°c @ idle. Help.

[Dr_Krieger]

Hi guys,

Query for you smarter people.

 

My girlfriend was playing Sims on my computer and it started crashing the computer which required a complete restart as all functionality was lost.
I decided to do some digging and discovered that my cpu's idle temperatures ranged between 36° and 83°c, this is without any overclocking at all. And during gameplay (e.g. Sims 4) it is sitting at 75°- 87°c.

I am running an ASRock z390 motherboard, EVGA GTX 1080ti, 32gb of g.skill tridentZ ram, and a CoolerMaster 212evo with a noctua P12 fan replacing the standard CoolerMaster one, and a thermaltake 850w 80+gold.

 

I have attempted to remount the cooler and reapplied artic silver 5 compound. I have modified the fan curve to operate at 70% until 80° and then 90-100% from 80°+.

Any help is appreciated. I have done a bit of googling already but it seems that most are running an AIO with their i7 9700k and are achieving roughly 20°-35°c at idle.

 

I have also noticed that the CPU usage is incredibly erratic and will show really high CPU usage with very little running. E.g. windows explorer was using 15.9% of my CPU and it was at 66% usage total. Totally stumped as to what is going on.

 

 

As said above, any help is appreciated!!

Cheers
Dr-Krieger

this could very likely not be the reason but your voltage  seems a bit higher than usual are you running MCE? also do you have the latest windows/BIOS installed?

[DoctorNick]

You're running intel multicore inhancement (MCE) - You can disable that in bios. Maybe get some better thermal paste than arctic silver. Get NT-H1 or Kryonaut. Go to BIOS if in EZ mode toggle F6. Go to CPU configuration - manual http://asrock.pc.cdn.bitgravity.com/Manual/Z390 Pro4.pdf

[Dr_Krieger]

I have left every bios setting at stock and have downloaded the latest bios driver from ASRock'S website.

Will check out the mce setting in a bit.

I am running the latest windows version aswell.

 

I will leave buying new thermal paste as a later resort as while I don't doubt the difference better quality thermal paste can make I doubt that it is this significant.

also another thing is, the 212 isnt that good of a cooler for that high end cpu so you might need a new cooler like an nh u12s or a h115i

New query for you, 

 

Is there really that much difference between a u12s and a 212 if they are both running noctua fans? (I have modified my 212 with a noctua fan)

 

Cheers for the help!

[WereCat]

When you got 83°C your CPU was pulling 140W... that's normal temp

your temps are completely normal. and idle temps really do no matter.

yes it does way more heatpipes and over all better design for thermal dissipation

Should be fine, unless you want to overclock. When you disable MCE, your temps will drop ~20c, because of much lower voltage.

[Dr_Krieger]

If my thermals are correct then there must be another issue causing Sims 4 to crash.

It was working fine prior to the upgrade on a gigabyte gaming b8 motherboard, i5 7600, and 16gbs of 1666mhz gskill ram

 

Any ideas? 

Temperatures were the first thing I noticed.

 

And I have not been able to find the mce setting in bios. Am I missing something obvious or does ASRock disguise this setting under something else? The manual would suggest that there is an mce setting but there is no indication where that would be.

 

Thanks again!

They do matter when they are at 83c

 

[Constantin]

Check the Task Manager if something is running and "steal" your resource.

83c at idle is absolutely not normal.

I have the same CPU with a similar cooler also changed the fans to Corsair ML PRO Push/Pull

And my idle is ~30c ish and full load max 75c

Actually they dont. 

 

 

As long as the temps are good under load. 

 

And since it was such a massive range of idle temps. It was most likely doing something.

Just to clarify, I had booted into windows, left to idle for 10 minutes then started up HWMonitor and left it for ~10 minutes. Unsure if that makes any difference to the point you're trying to make.

Likely a decompression/cpmpression workload that loaded in the background while you werent doing anything. 

 

Windows often try to find these moments to do stuff. 

 

In the end its load temps that matter. 

 

 

What temps when doing a cinebench r15/r20 run? (Just a quick benchmark)

Peaked at 98°c in cinebench r20

now that is a more interesting temp. 

 

r20 uses some AVX instructions. how are temps in R15?

 

load temps are certainly a higher than they should be. how is case ventilation? does opening the side panel improve these?

i skipped over this part. 

 

that there is a compression or decompression workload.

I had forgot to mention that I have taken both the side panel and front panel off to provide as much airflow as possible.

 

This is also true regarding initial testing.

 

Apologies for not mentioning earlier.

 

Will run R15 now

R15 ran at 85°c.

rough ambient temps?

 

wont matter if its 25*C or below. 

 

if r15 turns out badly. update Bios, reset the Bios settings. reapply your XMP profile. 

 

should remove any MCE if its enabled. 

 

re-do testing.

do sqeuential runs of about 3-4 in a row. (just to be lazy to not install extra stresstest software)

 

see if it levels out or keeps climbing

Rough ambient temp at the moment is 24°c at time of testing probably 27-30°. Hot as in Sydney Australia.

After 5 tests temperatures hit 88°c.
