I just build new system yesterday. My specs are:
Asus tuf z370
asus gtx 1080 ti oc
g skill 3200 mhz 16 gb ram
Samsung evo 960 m
cooler master master liquid 240 pro
Windows 10 pro
My problem is my cpu has temperature spikes. İdle is 30-31 and suddenly it goes 50*60*40 etc. On games, battlefront with extreme settings max is 65. On assassin creed origins on menu it is 80 and in game after a few minutes 90 and 97 degree. Does someone has experience those spikes and high temperatures also should i return this cpu or is there a fix?
I'm having the exact same issue, with virtually the same setup.
MSI z370-a pro MB
MSI Geforce 1070
fan cooled CPU--from Intel.
Nothing is OC.
Idle or just internet browsing the temperatures are in the 30's C, but under load while gaming it will run in the mid 70's C with spikes in the up 90's C. I just bought the computer, and I'm trying to make certain Intel thinks this is acceptable for the chips longevity. Those temp spikes seem very high.
What speed is your memory? Remember that you are overclocking at least part of the processor when you use *any* memory that is run at speeds higher than 2133MHz...
...Then you are definitely overclocking at least a portion of the processor and the potential for higher temperatures is there.
In desktop processors, intel defines three important thermal thresholds:
[Aside: As I said, you cannot determine the exact temperature at which the processor will thermtrip, but an individual processor's Tjmax and Tcontrol thresholds can be read from a specific Model-Specific Register (MSR). The IA32 Temperature Target MSR (0x1A2) provides the Tjmax threshold in bits 16-23 and the Tcontrol Offset in bits 8-15. Subtracting the Tcontrol Offset from the Tjmax threshold will tell you the value of the Tcontrol threshold. Tools like RWEverything allow you to read your processor's MSRs.]
So, what to do with this information?
Hope this helps,
I'm experiencing the same issue with my 8700k, something that concerns me is the Intel Burn Test, theorically it's used to test intel processors, so it should works well with stock configurations, but when I try to run this test my cpu reachs instantanly 100 degree... It's that really normal?
No Ernani, that is not normal. That is an indication that your processor cooling solution is either insufficient or improperly configured.
I'm right now using a deep cool captain 240ex and I tried other coolers, this is not my case, believe that, the only thing I did not tried to change was the PSU... can a bad PSU make the CPU generate this amount of heat?
This doesn't have to be a hardware issue with the cooling solution; it could be just the configuration of the fan speed control subsystem. The fan speed control configuration (likely configured in the BIOS but some boards come with runtime programs to do this as well) should be ensuring that, if the temperature of the processor is above its Tcontrol threshold, the fan/blower/pump should be operating at 100% duty cycle (i.e. full speed). Further, below the Tcontrol threshold, the duty cycle of the fan/blower/pump should be increasing from some minimum to 100% over some specific temperature range bounded at the top by Tcontrol. For example, from a minimum duty cycle of 20%, the duty cycle could be increased 4% for each degree that the temperature is above Tcontrol-20.
Hope this helps,
I have just read the very long temperature thread regarding the 7700 CPU.
I have just built a new PC.
AZUS STRIX Z370-H motherboard
Dominator 3200 GHz RAM, 16 GB.
MSI GTX 970 x 2 (SLI)
Kraken x62 water cooler.
WIN 10 pro
The temperature is all over the place when I game. Load seldom above 70 %. Spikes up to 85 degrees. Repeated warnings about temp from my software. The fans and pump keep the water temp at about 40 degrees C. I ran the diagnostic tool. Passed, and I saw no spikes when the test ran. Even at 100 % the temp was stable.
This can't be right? Or healty?
Scott, you make valid points, but you seem to completely disregard any problems with the CPU itself. The 7700 thread suggests excatly that. These are expensive CPUs and if there is a problem that may kill it earlier than normal, I would like to send it back.
Unless Intel can find a solution to the problem.
If your spikes are not going above 85c, then everything is likely working as it should. I can't say for sure, since I do not know what your processor's actual Tcontrol temperature is, but it is typically somewhere around 85c. As I said earlier, your processor can run at its Tcontrol temperature constantly, even for its full warranted lifetime, without suffering any silicon degradation. Short duration spikes above Tcontrol similarly will not cause any degradation, though longer ones that take the temperature above the processor's thermal load line can have a longer term negative impact.
I regularly see folks expressing concern regarding temperature spikes. They are not an indication of any problem. Because Intel chose to use TIM, rather than solder, between the silicon and the heat spreader, short-term spikes will occur because the TIM doesn't dissipate this heat quickly enough. Provided your cooling solution is adequately dissipating heat and meeting fan speed control requirements (i.e. running fan/blower/pump at full speed when temperature is at or above the Tcontrol temperature), the duration of the spikes will be kept to a minimum and no issues will occur.
Where you need to be concerned is if the spikes go significantly above your processor's Tcontrol temperature and/or last for longer durations. This is not an indication of a problem processor (as some regularly assume); it is an indication of an inadequate cooling solution or an inadequate fan speed control configuration.
Folks have also expressed concerns regarding how busy the processor seems to be. Its not the processor's fault. I blame this on Windows 10, which has a lot more going on in the background (my facetious response: it's all that spyware that is collecting all sorts of information about you and sending it back to Microsoft). You'll note thst it's only Windows 10 users who express this complaint ;^)
Now I found some solution to my case.
1 - I delited my processor, the thermal solution from intel is terrible, this gave me - 23,0º celsius degree.
2 - XMP profile to overclocked RAM is doing overvoltage in every aspect, so you need to undervolge the entire thing.
3 - use a good thermal solution and thermal grease, I'm using right now Thermal paste from Grizzly Bear, Kryonaut.
Now I can get at maximum 70º celsius degrees, before that it get 100º degrees instantly with prime95.
I'm very upset with intel and I'm thinking that will be my last intel computer.
I really want to know how a 95W TDP processor, running in stock configuration can instantly reaches 200W.
That is because they sell millions of the 8700k with no complaints. 8700 k work as they are designed, It is only your problem. You can run 24/7 100c for 3 years and Intel has your back
Thank you for your suggestions and help but ı strongly believe this 8th gen cpu's and 7700 k have serious problems about heating. İ just checked some forums tons of people have those heat spikes problem. İ have never faced this kind of a problem before even in my old amd and intel processors. Even i open calculator this god damn cpu create heat spike and goes from 30 degree to 55 degree and drops again.
Since I haven't been able to find the information anywhere else I used RWEverything to find out the TjMax and TControl values of the processor which are the following:
TJMax = 100C
TControl Offset = 18
TControl = 82C
I just purchased a new PC with an 8700K and using stock BIOS settings without overclocking it I can only run OCCT for about 10-20 seconds before it trips the overheat thresholds at 85C and shuts off.
This is with a CoolerMaster ML 240 Pro AIO water cooler. If I overclock it basically shuts off as soon as I click start on the test.
A little bit disappointing as I wouldn't have expected the temps to be quite so high (especially at stock clock speeds).
I guess I just have to live with this now
Somebody will come along and tell you it's something wrong with you, and that your CPU works as it should.
The big majority of users never look at the CPU temp. The PC works, and that is that.
Some of us look closely at what is happening, and sometimes we don't like what we see.
Your numbers look wrong. It could be your cooling or your CPU. If you cooling is OK, send the PC (or CPU) back.
I don't run into those temps running at 29% OC.
I realize this is an old post. But maybe this information will help someone else. The temps this person is getting are not normal. He has a problem with his cooling system or an issue with the CPU itself. I have a very similar setup. Intel I7 8700K with a Cooler Master ML240r RGB cooler. Running the Intel Extreme tuning app stress test for 5 minutes my max temp spike is about 62C. The temperature spikes up and down from about 50C to a max of about 62C with a spike every 5 seconds or so. This is running the CPU stock with no overclocking. Although I am using an XMP setting for 3200 Memory and also Asus Multicore Enhancement setting. I have had it hotter than that running Aida64 I did mange to get it to 70C. But thats the hottest I have ever seen it. In game an apps running a temp monitor. 64C is the hottest I have seen any core at running a very CPU stressful game like Assasins Creed Origins. CPU idles about 28C.
