9700k overheating

[D3adR4t]

Hey guys,

Recently got a 9700k system with corsair H115i, ASUS z370 strix - e motherboard here on carb. However i noticed with prime on default bios settings within 2-3 seconds all cores would hit 100 degrees. Even when playing metro during the intro of the game the cpu would hit 100 degrees within seconds, scanning my nvme ssd drive with windows defender would hit 100 degrees... What i have noticed is that when my cpu is at 100% usage, the voltage would go up to +1.4v and thus resulting the temps up to 100degrees and this is on default bio settings with no oc whatsoever.

Something is definitely not right here as my previous 8700k system with H80i performed much better in terms of cooling.

I have checked the cpu cooler and seems everything looks fine. Idling temps are also in high 30s, early 40s, which is a bit high concerning this beefy cooler. The chassis ventilation is also pretty good.

I do still have some thermal gizzy Kryonaut paste and will see if i can re-paste and reseat the cooler but dont think thats the problem as the 1.4v on cpu is more of a concern and probably the cause of the high temps.

any advise would be appreciated.

Thanks.

Try manually setting the voltage in bios to something safe like 1.2v ? I'm not sure what the stock voltage is but I cant imagine it being more then 1.1v If you are still having overheating issues at that voltage, then maybe the pump on the H115 is dead of has an airbubble in it from shipping? If so remove the cooler and give it a little shake should sort it out. At stock 1.4V is quite insane considering people are hitting 5GHZ all core at around 1.3v.

ASUS z370 strix - e

Asus motherboards are quite aggressive with their voltage and BCLK settings.

Manually set the voltage and BCLK settings.

Also check that your cooler is mounted properly. Like, as in try slide paper underneath when it's mounted and see if it can move. Sometimes, the mounting mechanism can be deceptively kak.

i think it definitly has something to do with voltage, as when i disable intel turbo boost, the system temps are fine, still not as good as with my 8700k/H80i but temps are under 70 degree max load but cpu is limited to 3.6ghz. However, with turbo boost enabled cpu goes up to 4.9ghz

 

[SILTECH786]

I run shadow of tomb on high settings no issues dload core temp app and post screen shot would like to see something
I have a hunch its that cooler

 

[DannyBoyOPC]

I had a h115i fail on me also. Check that both pipes are cool and not one blistering hot and the other one cold.

If that's the case ur cooler has bitten the dust

 

[BLUE-ANGEL]

Just my 5cents worth of info.
I have a 9900K running with a normal 212 CPU cooler and I can tell you I never hit that high temps nor that voltages.
I keep all my stuff stock, I don't like to overclock, guess I like to live on the safe side because of the new technology that has the turbo boost function, so no need to overclock for me.
My CPU according to my test results when I for ex. run Cinebench never really go beyond 1.285 Volts on 100% load 5.0GHz for all my cores. Max peak is 1.35V but that is the spike voltage, it runs on a steady average of 1.285V even ingame. Temperatures average at about 65-75 degrees while gaming at 1440p if I remember correctly, but I am speaking under correction for this.

My 2 cents, I just recently replaced my h115i as well with a deep cool castle 280.
I was hitting 100°C like you on my 6700k and i was idling at 50°C, now i get 20°C idles and 50°C full load and ive overclocked from 4.0ghz to 4.6ghz.

Im with DannyBoyOPC on this one because mine failed exactly the same as his did, 1 pipe hot, 1 pipe cold.

 

[D3adR4t]

Guys, thanks for your inputs and comments. I will check the pipes and also remove the cooler this weekend when i have time and repast and reseat the cooler and run some benchmarks again. However, those stock voltages are bit of concerning as i usually run my setups at stock not really much of an oc type of person.

8700k here on 5Ghz. Not the same chip, but I'm not seeing anywhere near 80 even with H100iV2. Did you repaste and seat the CPU when you got it or was it a bundle and you just kept it as is? Also check the software that controls your cooler's fan and pump speed. I've had so many issues where the profiles were just shit and never ramp up the fan speed when a component gets hot. Make custom fan curves / profiles.

Idle should be same as ambient temp +-5c. So if it's 30 degrees outside, you should be idling around 30 degrees as well. Remember you're just circulating ambient temperature air

It was the complete chassis with cpu, mobo, cooler and psu installed, and yes kept it as is did not touch any of the internal parts. I will check this weekend when i have time, but again those voltages at default bios. However, like i said i disabled intel turbo boost and seems to be working fine at max cpu load and voltages also below 1.3v

 

[iamgigglz]

My 9700k was running warm (80deg) at stock using an H100i Pro. Just for the hell of it I went into the Intel Extreme Tuning app and just set it to all core 5GHz without touching anything else and temperatures went ballistic.

I then set my voltage offset to -0.08v in the app and now I'm sitting at around 70deg under a synthetic load. Voltage sits around 1.35v, so it means my Maximus Hero Z370 board set the voltage to 1.43v initially...

Any lower voltage and it becomes unstable at those clocks which is a bit disappointing. Is a stable 5GHz all core overclock at below 1.3v the norm?

 

[Senshi]

How does this help him? Clearly he knows the temps he is getting is not right and doesn't need a baseline to compare it to?

@D3adR4t check your cpu voltages. I had a similar experience with my AMD when the cpu core was on auto, setting it to a fixed value manually fixed my issues.

If i wanted your opinion I would have tagged you dont u think i am a 9700k owner knowing well enough that his cooler is the culprit and not his cpu so a demo of what I displayed doesnt hurt .

If i asked your opinion I would have tagged you dont u think @Senshi

And no-one asked for your opinion on this thread, yet you gave it anyway?

@Senshi

There is a multitude of things that could be causing this. Just off the top of my head :

1. Bad cooler mount
2. Bad motherboard bios that messes with voltages
3. Bad/no thermalpaste contact
4. Faulty cpu
5. Faulty motherboard
6. Faulty psu
7. Faulty cooler

Just because you say it's the cooler doesn't make it so. Going by the ORIGINAL post, the 1.4v seems pretty high, and is most likely the cause.

If the cooler was at fault, it would exhibit the same symptoms under low load as well as the heat would build up over time.

So can we get back to trying to help @D3adR4t and not telling him stuff he already knows?

P.S next time somebody has a problem with their car, stop yours next to them and tell them "look mine works", see if that helps.

 

[noa]

so a demo of what I displayed doesnt hurt .

It didn't help either.

Check the MCE setting in your bios. If its on then you board will auto OC the 9700K to 4.9Ghz on all cores. The 1.4+ Volt reading sounds like this is the case, because with MCE it uses a high auto voltage. Turning this setting off should decrease the voltage a bit. You will also be able to archive better voltages by manual OCing. For reference, my 9700K does 5Ghz at 1.32V which seems pretty average from what I have heard.

If you temps spike up to 100 within seconds then I would also suspect the cooler, I have seen this with my cooler when I forgot to plug in the pump cable.

There is a video from MSI where they guide you exactly with more or less steps and settings for overclocking the CPU, not sure how different it will be for other brand mob's. I believe they did 5GHz or 5.1GHz stable clock speed. When I did the research on people overclocking the i9 9900K to stable 5.1GHz, they all mentioned a min of 1.35V for that high clock speed to sustain stability and to safeguard the little processors inside the CPU itself, I never saw 1.4V or higher, I think highest I came across was 1.385V, but I believe that guy pushed a little bit more Hz...BUT, you will need a watercooler because of the temps will go through the roof. More voltage = more heat.
In my case I don't overclock so I just did the little research out of interest to see what people can do.

I personally don't own a watercooler, but I have seen videos relating to what the other guys in this post mentioning about 1 pipe hot other one cold etc. Apparently the pipes can build up some gunk inside that will eventually cause either restricted flow of water or cause damage to the little internal fan that pumps the water through the CPU cooler and having your cooling system to fail.

@Senshi

Hey Bud, at least you tried to give him a baseline of what he should be looking at for a stock 9700K

 

[BLUE-ANGEL]

This comes off MSI website directly just to give as a guideline, so each CPU is clearly different in behaviour to overclocking when it comes to the needed voltage.

MSI:
"Our recommendation is: 1.32v for OC i9-9900K 5GHz, 1.37v for i7-9700K 5GHz and 1.43v for i5-9600K 5GHz. Each CPU needs different core voltage for stability. If you're lucky to get a good chip, you may need lower core voltage for a stable 5GHz than what we've suggested. "

 

[dRweEz]

my 2c,

sounds like bad mount or pump is not working.
install icue from corsair, hook up the cable from you 115i to the usb and from there you can see the pump rpm and temps

if everything is fine with the h115i then you might be super unlucky that the internal connection between the die and heatsync is BAD.

you are welcome to send me the cpu to be tested if you would like a 2nd opinion

Sight... i dont have time to go through all that testing again. think best is to test my cpu in another system or test another cooler in my system. but i dont know anyone in my area with a z370/z390 system.

Like i said will first repast with Thermal Grizzly Kryonaut and refit the cooler. will also feel the pumps like before mentioned regarding the one pump being very hot and the other cold. Will also try to set manual voltage although i have no clue with overclock cpu or asus motherboards (maybe assistance from this lovely community will help).

Thanks again for all the input gents!

i already disabled multicore enhancement and no luck, the voltages did drop a bit though but still hit 100 degrees. Like i said the only solution now was to disable intel turbo boost. However, the core is fixed at 3.6ghz but temps are in high 60s on max load. Still not what i expect from a beefy 280mm rad cooler.

 

[superrob]

Have you tried turning it on and and off again

@SILTECH786 can do this with ease with women sweeties = ON ; no sweeties = OFF ;

 

[Micheal]

Make sure the heatsink is touching the processor .........

don't forget to install the usb cable to the h115i when you re-paste so you can monitor with iCue.
push comes to shove and you are stuck with the config i can do a quick live stream on the z390 gene with an h80i

When I got my kraken on my 9700k my temps were over 80 and I thought damn I got a dud pump.

Realised didn't have the USB cable plugged into the pump. And bam 30degrees.

Something about the temps not syncing with the software and wasn't controlling properly.

But ye make sure that cable plugged in and the cpu seated nicely and not over tightened

Good luck

what USB cable? are you guys talking about the corsair link cable?
