Yesterday I took my pc to the store so they could see what was wrong with my cpu as it was reaching 86C while playing the Witcher 3 (this temperature was during the winter). Today they told me they weren't sure what was wrong with my pc but they somehow fixed it. They told me the person who built it probably didn't do it right.. They reapplied the termal paste, cleaned everything etc...And then they said the cpu temp wouldn't go past 65ºc during the stress test and that I didn't need any aditional fans (I had requested). Then I got home and played for a bit and it reached 86ºC again. Now..they have air conditioner and I don't. Could that make THAT big of a difference (21ºC+)?
I mean it's hot in my room, I can go around shirtless but it's not like it's burning in here, I think lol...

Specs:

Motherboard Asus Z170 PRO GAMING Aura
i7 6700k (no overclock)
cooler CPU Cryorig H7
ASUS GTX 1080 STRIX AURA Advanced
G. Skill Kit 16GB DDR4 24000MHz Aegis
SSD Samsung 750 Evo 500GB
Western Digital 2TB SATAIII 64MB
WIndows 10
ATX Corsair Carbide 300R w/window

My english is rusty :p

No need to feel dumb buddy :)

Disabled auto vcore and set it manually to 1.250 Vcore.
As I sayd, you can try lower if you want. If the system will not go past post or the system freeze in windows loadup or in windows, games, etc you have set the Vcore to low. And 1.250 should be enough for running stock with turbo boost.
Play around with it up to 1.350 Vcore and you can not do anything wrong. Exept from seeing temps go up and down depending on what Vcore you set.

Leaving it on auto lets the motherboard run all the way up to 1.500 Vcore.

Have you OC the cpu? if yes whats you current GHz and volt settings?

If running stock... Look below :)

Unless there is a 21ºC+ difference from your room to the shop, then no.
I would take the computer back and tell them that you want to look while they run the soo called stress test they have runned on it since playing solitare or reading news on the web is not a stress test.
Something is wrong with the seating of the cpu cooler or the thermal grease is not correct spread out. Or a mix of them both.

No, it's not OC'd, sry I forgot to tell that.
And unfortunately I can only go there Monday... And yes, this time I will make sure I see those max 65ºC Temps with my own eyes lol.

(Something weird they left on my desktop was a HWMonitor shortcut that would freeze my pc everytime I tried to run it...it seemed to be an older version but I'm not sure , I uninstalled it. I used a newer version and also realtemp to check temps. They seem to be rather jumpy but then again I understand 0 of this lol.)

Since it is not overclocked then the temps are not normal. And if you have done nothing to this computer exept looking, then they have done something wrong.

Again you have the right to see what they are trying out on YOUR computer, and I would demand they fix it at the same time I would also demand to see the stress test they use.
And they can use the the HWMonitor that you are using to look at temps so you and them get the same read outs.

Apart from my cat who ran past me at full speed, pulling my controller cabble which almost knocked the pc on the floor, nothing happened to this pc xD. I had these problems way before this little accident though. The pc was build on another store btw, but it's too far away from my home now. I'm going to follow your advice and demand they "repair" the pc in my presence.

I already did that and I'm still getting the same temps. One thing I noticed was that Microsoft one drive was using 15% of my cpu. My iddle temps were between 35ºC and 60ºC+. After uninstalling One Drive (because I don't even use it), they're now more stable between 30 and 35ºC. The max temps when gaming remain the same though...
I don't want to think they're this stupid but I'm even wondering if all they did was checking the iddle temps, and that's why they got a max temp of 65ºC. But then again that would still be very hot for iddle temp.

Anyway... I'm going there tomorrow...

EDIT: Are these voltage values normal?

1.408 volts??
Thats high for an air cooled cpu. Go and set vcore 1.250 with adaptive setting up to 1.300. You can even try and go lower and I would belive you could on a stock cpu.

Problem is that intel dont set a default vcore for the skylake / kabylake cpu`s (if I remember correct but I could be wrong here) and motherboard manufactures are setting a higher Vcore than needed to make sure the cpu`s can run without problem.

Ok, so... there seems to be a huge improvement...

http://imgur.com/IUpIa7m

I went to the bios, then advance settings and changed where it said CPU Core voltage/ cache voltage (something like that) from auto to manual, and then it opened another thing where it said something like override core voltage and I put 1.250. I started windows with no problem and left the witcher 3 running, temps didn't jump to high 70's like they used to, instead they went to 61º, but after a while they slowly rised to 67º. Did I miss something? You also said something about adaptive in your other post, which I didn't do. (Even though my temps are lower, the air coming out of the case feels hotter, but that's probably just my imagination). Anyway I need to leave the gaming running for a bit more to be sure..


EDIT: OK so apparently the temps are not rising like I said, but they are instead jumping from 58ºC to 67ºC usually (at one moment went as low as 55º C and in another instance it reached 69ºC). Are these fast changes in temp normal?

Just leave it as is atm. Setting adaptive volts is for AVX workloads ( normaly you dont run into them in normal day to day use ) like Prime95 uses AVX and that is brutal to the cpu, you will not experience thay kind of workload on the cpu doing gaming at all.

The air only feels hotter out the back dont worry :)

Your volts atm looks fine, but like I sayd, you can try and go lower on the Vcore. Try 1.240 Vcore and see if that is stable AFTER you have tested for 1 - 2 hours in witcher 3 with current Vcore settings.


And atm your temps are spot on good for an aircooler. Post your temps after doing gaming for 15 minutes ( go somewhere there is action so you get the cpu / gpu to work alittle )


I will be back later on tonight and check your results, cause right now its food and movie with the wife.
But good to see you are making progress :)

Ok, After playing for a bit (and the browser opened), my max temp was 72ºC...(GPU max temp was 76ºC). It did crash on me once but it didn't show any error... I looked in the erros log file of the game but it doesn't show the erro's date. I'm going to play a bit more and see what happens and check the log again and see if anything new shows up. I'll probably have to increase the voltage if it happens again.

EDIT: Actually , it creates a diferent file everytime there's an error. I tried to recreate the crash(something with the horse lol..) and it worked so I believe it has nothing to do with the change in the voltage numbers...Maybe I can go even lower then :)

Temps rising up and down fast is normal. It all depends on the steeping on the cpu ( what speed it is running that very second ) All that matters is how HIGH it goes in temps.

72ºC... That is totaly fine and well within limits :)

And the crashing part of the game sounds indeed like it is just the game that makes that happen. But like I sayd, if you want you can play around with the Vcore in bios up to 1.350 but dont push it any further since you temps will start to go high I think.

Just as a sidenote: If you go to low and windows crashes and you do that 1 to many times. You might have to reinstall windows all over since sometimes the files in windows get corrupted... So dont go pushing the volts to low to many times... If you are happy with the temps now and they are fine even if I would like to see something in the 60 degree area. 72 is just fine. As long as you stay below 80 - 85 degree celcius.

Ok :) Just one last question. Do you think I can have damaged my cpu in any way by having these high voltages for 8 months?

Actually two lol. I think I saw the cpu fan graphic in bios and I think it's set to start spinning faster at 70ºC. Changing that to 65ºC would not reduce the max temp, right?
