Thermal sensor issue i7-7700k?

[CK7]

I have a brand new build; EVERYTHING NEW. i7-7700k is running at stock speeds. I have the RAM set to XMP for DDR4-2666. Motherboard is Asus Maximus IX Hero Z270.

I have found that the i7-7700k reports a momentary (a second or less) temperature spike +25 > 35 degrees Celsius anytime a program is opened, a webpage is opened, a background app runs etc. The temperature blip cascades through the cores in random order; not the same every time. This causes my heatsink fan to constantly cycle up and down. Temperatures otherwise report as steady, normal increases. Peak temperature under Prime95 blend test is 71 degrees Celsius.

Attempted solutions:

I have re-installed my heatsink and thermal paste with no change.

I have tried to manually set my fan speed in the bios. The only setting that avoids this issue is setting the temperature / fan at a constant (and loud) 80-100%. I've tried PWM and DC mode.

I have found a few user reports elsewhere on the web, all reasoning that it's just the way it is. I don't accept that. Opening a folder or browser should not spike temps +30 degrees. Not only is the fan cycling annoying, it puts undue stress on my fan; possibly shortening its lifespan.

What's the answer, if any? RMA?

Hi Meedy.

I think you'r having reboot problems because of your settings. You'r using a extremily low voltage for a 4.7Ghz OC. It dosent make sense. I think you shouldnt expect a stable OC with those settings. Why dont you try this settings:

Vcore - 1.2V or a bit lower

Bclck - 100.00

Multiplier - 45

and maybe a negative offset on avx instructions of 1

Also try: level 2 on cpu load line calibration to reduce temps under load.

Having an OC without HT, turbo boost and all the things that make this cpu the king, it's not worth it. Because it's an OC that simply is slower than stock.

PS: Dont be affraid of higher temps while gaming. Let it reach high 60's that wont be a problem.

Also for solving fan problems i put threshold @ 60°C, so unless my cpu rise to 60°C my fan stay at lower speed.

After a few days i'm now running it @ 4,3Ghz HT 61°C on air cooling.

Dunno if i send it back yet to get another cooler model, i'm not sur about running an OC'ed cpu @ 80+°C , in fact the specs are 100°C and seems to be 64°C for the 6700K, maybe we are not used yet to run the cpu at those temperatures...

Does someone here own a 6700k ? Is it cooler at same freqs ?

Hi mate ,

Well it s stable now with 1.9v ( even i know it's not a real OC since i've disabled the features make this cpu " KING " ) but i'll try your settings and feedback

it would be much great if it runs max 60C , but i'm afraid it won't ..

I hope the 1.9v thing is a mistype. That type of voltage will fry that chip in no time. Just hoping you meant 1.09V.

Yes guys i do understand everything you've mentioned , i'm a costumer and a victim just like you are , if i took this drastic way to reduce temps , it's because i wasn't comfortable playing with spikes that has reboot my pc a few times ..

so i had to do something about it , because i've read every single message here and i've found no REAL solution from intel ( which they're supposed to fix this cause i'ts their product after all ) , but yeah what should we do , i'd like to change , but if i switch to AMD i will have to switch everything with and i just bought these stuffs i'm lost and i don't know which way to take any more :/

These type of posts do not help. You are not a "Victim".

Things happen. Some chips are worse than others and this being a new chip I can understand why there are consistency issues. I am sure they will make this right one way or another in the end. The speed of that solution I am unsure of, but even now if your chip is THAT bad you are able to RMA it. Which I would recommend you doing if you are indeed seeing stock temps at 95C.

Switching to AMD is also an option if you only recently got the PC. Just return it to the seller or place you purchased from. Most of these places will allow a return within 15 or even 30 days.

I will say this though. AMD has it's own issues with ryzen.

Lastly to those pictures that were added a few posts back. The difference between the two is clear. The intel solution is using a TIM paste, where as the AMD chip is being soldered to the IHS. This is what intel use to do up till sandybridge. After sandy they have been using a paste and one that has been hit or miss the whole way. Hopefully they will go back to a soldered approach then delidding will become a no longer needed practice.

Meedy, I would just return that chip for a new one. Then you will at least be able to narrow down a few more variables.

Well by saying victim you know what i mean but not a victim by the words meaning .. anyways chip is stable now and i can play games on max 63C , with HT EIST and everything enabled , althought i had to reduce CPU PLL a lil bit to 1.2v since it was on auto 1.3V , the pc i've build it myself , not bought it pre build , and my bad yes i mean 1.19V not 1.9 my mistake , i am on 1.2V now 4.7ghz , everything enabled , seems stable to me no reboot no spikes not very crazy high temps so far ..

Ok, I'm a little confused about some of the posts I have been reading.

I want to address some issues, with some questions.

1. Why are people complaining about briefly hitting the 70's in gaming? some people even annoyed being in the 60's. This is perfectly fine, it always has been.

2. Yes there are spiking issues, and I understand the concerns if it is spiking into the 80-90's as it's a bit horrible to look at, when it shouldn't, but this is USUALLY remedied by turning down voltages, as auto settings have the tendency to over volt as I have said before.

3. Intel are NOT going to fix this, unless they re-call all chips and send them back out with better TIM/Liquid metal, period, so don't be hopeful. There is no other way to fix it.

4. My temps are okay, idle is un-important (but I idle at 24-31) depending on ambient. During gaming I BRIEFLY hit 73 sometimes on Battlefield 1, but its just a spike, then goes back to 59-68 area, I have HWinfo open and my averages on BF1 range from 63 to 67. This is perfectly acceptable, are people disagreeing here?

I also run at 1.328v, with a 5GHz overclock, and I still have 'decent' temps, well within what is considered safe for long term use.

I fully agree with you.

1. Why are people complaining about briefly hitting the 70's in gaming? some people even annoyed being in the 60's. This is perfectly fine, it always has been.

Honestly, i care a lot about temps and i can fully understand those that complain about hitting 70c in gaming, max temps i get in Gaming is 33c and rarely it spikes to 38.

2. Yes there are spiking issues, and I understand the concerns if it is spiking into the 80-90's as it's a bit horrible to look at, when it shouldn't, but this is USUALLY remedied by turning down voltages, as auto settings have the tendency to over volt as I have said before.

Agree with you about that too, and i have seen that there are some 7700K that the spikes higher than others.

3. Intel are NOT going to fix this, unless they re-call all chips and send them back out with better TIM/Liquid metal, period, so don't be hopeful. There is no other way to fix it.

I don't think Intel will fix this problem because as you said they have to re-call all Chips and that is going to cost them a lot, but replacing the TIM will only solve the heat issue and not the spike one, one more

thing you have to take in consideration is that as you can see Intel sold/sell those 7700K without heat-sink what it means at the moment you buy one 7700K you should know that you will need a decent/adequate Cooler or Watercooler System,

but many users buy a cheap 20$/30$ Cooler and then they complain when the CPU hits 70c+.

4. My temps are okay, idle is un-important (but I idle at 24-31) depending on ambient. During gaming I BRIEFLY hit 73 sometimes on Battlefield 1, but its just a spike, then goes back to 59-68 area, I have HWinfo open and my averages on BF1 range from 63 to 67.

My temps are OK too, idle is 20-21 and when i open Firefox it spikes up to 30-32 ( not bad at all ) my CPU runs at 5.0GHz 1.36v, but the reason i get low temps and low spikes is because my 7700K is De-lidded and i am using a Water-chiller system, i could even make it run cooler if i want it but those temps are more than ok for me.

sometimes i used to have my 7700K running at 5c-10c idle.

This is from today - room temp 21c

If your gaming spikes are 33-38??? WTF cooling are you using and is your chip default clocks?

And btw I have 160e water cooling and still I will hit over 70+ if I overclock my chip to 4.9-5.0

Now I solved this problem and I am fine without overclocks and my vcore is 1.15 and my gaming temps are 55-58. (BF1, Forza Horizon 3, F1 2016, Call of the Wild).

[AElib]

As i have said before i am using a Waterchiller, and as i have said before too my CPU is Overclocked at 5.0GHz 1.36V.

You are running your CPU with 1.15V and your temps are 55-58 and i am running mine at 5.0GHz 1.36V and my temps are 33c in Gaming, that is why i love Waterchillers Btw with my WaterChiller i could low my temps up to -5c

I drop my temps -5c just for bench.

[LRibe2]

Man... those are some incredible temps... lower than ambient. Lol amazing. Makes me wanna delid mine..

I agree with RitchieDrama, these temps are normal temps for this CPU. The diference between his build and mine is that I have the same temps, maybe 1C to 3C lower but running at 4.7Ghz... But I use a non delid chip with an CM EVO 212 inside a mATX case.

I think these is a regular performance using this setup.

[LRibe2]

LOOOOOOOOOOOOOOL

You have a damn fridge in your bedroom.. naaahhh not my type of solution! But man...that's some scary performance!

[ASušt]

Yeah, now we will all buy a fridge

It's not the problem of average temp during gaming etc...

My Noctua air cooler handles pretty well even with constant 350rpm (lower limit).

The CPU holds somewhat stable temp while I play (intel gtx hd630 ti Xpe...).

It's the problem of CPU spiking there, where no load can be found.

Intel, give us some news!

[AElib]

Don't pick me wrong guys, i have that Waterchiller since my 2600K.

[idata]

I think people need to get back to the OP's point - the spikes during idle, or superfluous tasks like opening a browser. Not the right analogy, but I was explaining to a mate its like a car revving at the lights over and over and over without you putting your foot on the pedal.

The spikes do not appear to be happening under load, and people have varying degrees of load temps (some a lot higher than others, which does need looking at). De-lidding is not an option for some of us who either don't want to void the warranty on a £300+ piece of kit., or those that don't have the knowledge or expertise.

We need something concrete from Intel.

[AElib]

There are some spikes under load but are just 2c-3c, at least in my case.

De-lidding is for those like me who don't care about warranty and if i fry/damage my 7700K i go and buy a new one.

[ASušt]

A little update from other topic:

"

In regard to your inquiry, at this point there is no estimated time frame of when Intel will provide a possible resolution about this subject, let me apologize for that, there are no details yet on this matter and right now the best thing to do is to keep checking the original thread, since if there are any updates from the investigation they will be posted there.

Once again let me apologize for any inconvenience.

[PGarc12]

Same issue here...

i7 7700k

MSI Z270 Pro Carbon

NZXT Kraken x62 (watercooling)

I'm amazed of seeing 26 pages of thread and no solution yet from Intel, and by the way... seeing how bad i7 7700k appears to work related to temps, it deserves a product replacement program, because it's quite clear at this stage that a lot of 7700k has this issue. If I had know this I wouldn't have spent 350€ on it...

Hope to find a solution, but being honest and seeing how much time it's been around, and how many results you get by searching 7700k spikes it's not even close.

How can I attach the XML file? can't see nowhere to do it

[AElib]

Sorry to disagree with you but it doesn't work bad at all, it depends the Cooler and voltages, i guess maybe your runs hot because you are using a Watecooling instead a Watercooling

[PGarc12]

Really ZeoxZariX ?...

BTW: I said it works bad on temp reading, didn't said it runs bad in performance. But a premium component like this one (high-end series) shouldn't have this kind of issues, and the worst and what worries me more is that after 4 months almost nobody has raised any solution, when there's enough info out there to clearly see these processors, or at least some, are faulty.

And my cooler works, at 30º Idle stable and my voltages are stock ones, haven't tried OC'ing this and won't do knowing I can't control well temps... I won't put risk onto such expensive piece, not at least until I have a secure way of reading it's temps, and jumping 30-40º in a second doesn't helps at all.
