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?

Why would you not set the vcore to a reasonable level and then blame intel for a 3rd party issue?

No man! Its not 3rd party issue! 3rd party issue is when some Noname china m/b out with Z170 which they buy on black market. In that case we talk about certified m/b vendor. Intel sell them their chipsets. They manufacture motherboards. And everything WAS fine. Its certified m/b vendor duty to set correct vcore for processor.

What Intel can do?

1) Intel owner call ASUS owner and explain him that if they want continue manufacture Intel chipset based motherboards they should READ THAT FUCKING MANUAL about processor specification and stop overvolting it!

or write big black text on processor specification page

2) Sorry guys. We sell our chipset logic to idiots. They can't read processor specification and will overvolt our processors. So you should set up vcore in your BIOS manually. We apologize for that.

^^ this is how normal business works!

P.S. End users should not tune up ANYTHING in BIOS when official CPU vendor and their certified chipset logic vendor said that hardware is 100% compatible. And I'll never change my opinion about that.

hi Team,

this conversation has become farcical...

we actually use computers to do actual work & gaming...

i am a newbie to OC'ing & i must trust the component manufacturers to head people, as myself, to sensible outcomes...

the only reason anyone would OC would be to get tangible results - actual extra workflow throughput (apart from bragging rights) - after reading this forum i am currently happy to run @ 7700K stock (still pretty fast & solid performance)...

i find it very interesting that with all this talk of processor 'performance', 'voltages' & 'package power' - there has been zero PassMark, AIDA64, Intel XTU, Real Bench - & so on - actual performance levels - this is not all a 'black art'...

my story is - 4K60p is the Holy Grail!

i can playback professional Canon MJPEG 4K 60fps footage perfectly with DaVinci Resolve - does not quite do it in Premiere Pro CC (however, 4K 30fps plays perfectly)...

Forza Apex 6 plays @ 60fps @ 4K almost perfectly...

Elite Dangerous (2.3 - just released) gets close to 60fps @ 4K...

DiRT Rally (from 2015 - DiRT 4 about to come out June '17) only around 40fps - no DX12...

GTX1080 Strix is very helpful...

the reality is - if one is actually interested in performance - SOFTWARE design plays a huge part in performance...

& yes, we now all now know the 7700K is a hot chip with temperature spikes - i wonder what Intel has to say about this extra heat on long term performance (3-5 years +)?

cheers, craig

I am a mod on another forum, and if I was modding here, I would be deleting posts.

Lets stay on topic here please, rather than bicker and snipe at each other as this does nothing to help.

Again, there seem to be two issues. Spiking during idle, and high temps under load and Stock or OC'd, does not seem to matter.

De-lidding seems to have made a massive change (spiking still happens, but to a far lesser degree, while also dropping load temps) but I doubt Intel will be offering that (but I live in hope!)

So we wait on Intel's response. Wether this is in the form of a bios update, which hopefully is not something that masks the temp spikes (in my case), or a confirmation for those with high temps to return for a free replacement.

Nah, dont pretend to be something you're not.

Let us share our options and if you don't have anything helpful to say please keep out of our conversation.

Thanks in advance.

This is a post discussing the topic at hand, not a place for you to hold a conversation that is not on topic, surely?

[TGrab1]

Actually Asus, Gigabyte, Asrock, MSI, etc... are all 3rd party vendors.

Intel designed the CHIPSET and then lets these vendors use it... so while their boards are based on the intel chipset they use their own designs for the rest of the board including the BIOS/UEFI.

Intel has no hand in how they design or setup their Bios.

So voltage issues when set to auto are issues with the 3rd party you purchased from. Which again are Asus, Gigabyte, Asrock, MSI, etc...

As for end users not touching bios... If you are building your own pc or that of others you should know these things regardless. Take your pc to a place like microcenter or bestbuy geek squad with these issues and I can tell you now.. chances are they would tweak voltages if need be and get it back to you. The A+ exam covers these areas now ffs.

Also people who are just building a basic pc and do not want to touch the bios will rarely buy a K designated chip. Companies buy directly from the big names, people looking to save a little and build their own for business would go with a plain motherboards from a big name normally and then throw in a 7700 or 6700 or whatever they wanted but it would not be a K line. These people aren't seeing that same issue.

My motherboard for example isn't one that overvolts my chip on auto... not that I am even using auto. Lots of motherboards have fixed this issue when a few simple bios updates. The older z170 line has had this issue and has also been slower in addressing it via bios update from my experience. Part of this is because the z170 while able to support the 7700k was designed mostly for the 6000 series.

Now let us go back to addressing your cooler. You said it is 200% more than you need (which is false) you have also stated to tried another cooler (have told us nothing about it) and still had issues. So what cooler have you tried? Im not saying you need a 100+ dollar cooler for this chip btw, but you do need one able to dissipate more heat than the one you provided earlier. I didnt even touch on how much heat that chip produces at the 1.3V+ you said the motherboard had it running at (It jumps to 191-205w of heat at 1.33V btw)

Anyways you have said you adjusted your bios and now have acceptable temps if I remember from your last post. So while that does not say there is not an issue with these chips that intel needs to address... it also means that the 90c+ you were seeing in stress testing was to due with over-volting more so than anything else.

That all being said. I AGREE there is an issue with these chips. I firmly believe intel should use a different solution for contact between the Die and IHS. That could be a better tim, a new liquid metal solution, or better yet just soldering the chip to IHS like they did in previous i7's like sandybridge.

Everything else about the chip is very good, the only issue being the thermal situation that comes from the TIM used and the uneven application of the silicon sealant. If these two issues are resolved then the chip performs like a beast. My own delidded chip can pull 5.1ghz under 70C... I can run it at 4.8ghz at 62-64. I can run it at stock in the 55C range... this while using p95 stress testing in a room that is anywhere from 23-25C. Most delidders have seen the same results which just points for solidly at the issue I have outlined.

TGrable, my reply was to ZeoxZariX. I understand your point and your good intention, but is clear that we are in front of a CPU issue. If you (or others) are asking about other possible causes only adds confusion to the main thread. Of course you can be right in many cases, but this understimate the importance of the problem, and takes off pression from Intel, who should be under a big pressure in front of that evident issue.

All of us are doing all we can to mitigate issue' annoyings (or dangers!), but the issue is still there, and this, in my opinion, cannot be deduced from your advices (sometimes is like us, users/customers, are guilty of doing incorrect things).

[DBux]

And I replied too. I will summarize: please, don't use this complaint thread to other questions; is too much easy to loose the point (not a thread about how to overclock, not a thread about the best hardware, etc.). I think is the best way to don't become defeated by ourselves.

[ASušt]

I have written my thoughts before, and i'm completely agree with creocoder

About buying a 200+$ cooler just for not letting this CPU melt the floor. (Remember that it has it's stock cooler in the box!)

I don't have a GPU right now, so I can't play almost any demanding game. Basicly my PC now is just an office PC.

And It spikes with a 80€ cooler inside 200€ case with 4 30€ fans. No OC, not even XMP. Isn't that too much for "just work"?

About Intel not contacting MOBO manufacturers....

About that "End users should not tune up ANYTHING in BIOS when official CPU vendor and their certified chipset logic vendor said that hardware is 100% compatible."

We can OC, but if we don't OC and tweak and everything else, it MUST work fine on it's own.

So once again, creocoder is right, they want money from us, but sell crap, that users must tweak and finish themselves.

Really?

I didn't get any Cooler :-(

This was my first post in this Forum it can be found in page # 1

The spike issue it's something common on all 7700K CPU's

These are very hot chips for sure. In addition, I experienced as have many other users extreme temperature spikes on the cores. I have never seen that before in any Intel chips. I have seen uneven core temps but not spikes at random times on random cores, so anything you could do to help it thermally would be great. However this could be Bios related voltage issues that will get ironed out.

I still believe that a Bios update could solve the problem.

Where is the guy, that told us about MSI mobos are issue-free?!

About stress testing: ran AIDA64 stress test 10 min (stress CPU,FPU,cahce,system memory).

My coolers are at constant low speed. This got me to 80c.

A stable temp during tests.

And after i finished the test, a notepad launch got me a 65c spike.

Totally equal load.

[ASušt]

I ment "totaly equal" between a 10min stress test and notepad launch in terms of temp.

[AElib]

I know what you meant.

My temps are under control and the spikes too but at the end i don't care at all because as soon as Intel release a new CPU i will be building a new Machine.

[TGrab1]

I decided to see what I my actual temps are at 4.5ghz since I keep giving a ballpark but i never recorded it so want to make sure my comments are accurate. I haven't used OCCT much, but saw others have been so decided to use it since it has temp built in.

So I ran at 4.5ghz, It was a small FFT test run for about 10 minutes to get a good average temp. My room temp is currently about 23C.

I will say I had something going in the background when I launched this.. so the idle (min) temps aren't accurate as I was checking email and this forum as I got it ready haha... so idle temps are normally in the 28-30C range.

That being said this is what I meant about the chip having a poor Tim. When I first purchased this chip my temps would be in the mid to high 70's with the same setup. Also note the actual Vcore my chip requires versus what it is requesting from the motherboard.

It only needs 1.14 vcore to run at this speed, but the chip is requesting 1.23 from the motherboard and if the board was on auto it would probably be running at 1.20 after vdroop for this test.

So this is more an example of what tweaking your voltage and delidding can do for temps. For me it resulted in a 25C or so drop across the board. I can crank this chip up to 5.1ghz and it still run cooler than it did with the stock clock before delid... to me that is just crazy

[AElib]

I am done with the whole 7700K thing, i will wait for the 78xx serie.

[RG9]

Just ran Cinebench 3 times, did a GTA V benchmark and have been surfing the web for the past hour or so and the max temp of my CPU per HWMonitor is 56C. The big thing is I'm running my memory @ 1.2V 2400mhz. CPU is running at 4.7GHz adaptive, 1.2V (ASUS MultiCore on Auto). Passed quick stress tests using OCCT (10 mins, 67C max) and RealBench (15 mins, 63C max).

[AKoch8]

Can you post full name of your m/b?

ASUS ROG Strix Z270i

Just finished another OCCT quick 10 minute test and the max temp is 69C

[cmack2]

very good work SpikeCity - i would like your performance & temps - running a stock Z270 Tuf Mark 1...

extremely detailed BIOS settings would be appreciated!

the worry is with a hot chip - there will be degradation over time - Robert provided an excellent reference:-

may result in accelerated "Electromigration" - https://www.google.com/?gws_rd=ssl# q=Electromigration https://www.google.com/?gws_rd=ssl# q=Electromigration

(it would seem to me to be simple physics)...

TGrable has been extremely helpful to us all on this forum - thanks - i must say, however, a well setup 7700K performs better than a standard 7700 (non-K), even @ STOCK... (& i also note TGrable's consistent comments on poor 7700K thermal - as manufactured - deployment)...

i, like creocoder, would simply expect the collaborative manufacturers to be more on top of this TEMPERATURE ISSUE than many on this forum seem to actually be - right now...

Intel & the mobo manufacturers should TAKE NOTE of the many sensible contributions that have been made by many on this forum...

btw, my ambient temperatures change between 6 & 48 degrees celsius over the year...

cheers, craig
