[SOLVED] CPU high temperature

[Vlade]

I was playing a game called Miscreated with highest settings when I noticed that my CPU is really hot. It was going around 75-83°C and it peaked sometimes even higher, HWMonitor saying that the highest was 89°C. It was also showing that CPU is only at 40% usage so I feel that there must be something wrong when it goes that high. I tried to lower the graphics and that had only affect to the GPU temps, which was also pretty high 75-80°C untill I manually set the fans to go 100% and the temp of GPU dropped to 70-73°C. I have overclocked my GPU and enabled XMP from bios, but haven't touched the CPU. I'm running the stock cooler and I have seen CPU going high temp in other games too, but not that high. So should I upgrade the stock cooler to better one? Or do you think the thermalpaste is faulty? When I was building the pc I didn't know that the thermalpaste was already in the cooler so I put the cooler down to the table like that the thermalpaste was against table. After that I didn't see anything wrong with the thermalpaste, but maybe there got some small dirt or something to it and now it's faulty? I builded this pc like 1,5 months ago.

To be honest
In some motherboard Bios or Uefi enabling XMP does alter CPU including voltages speeds and some other things to match the frequencies of faster ram speed
While some motherboards on XMP do even advise you of having a CPU liquid cooler
On stock cooler its not advisable to use XMP profile especially if its altering CPU

I guess your CPU is getting overclocked and hot
80 to 90 degrees is considered HOT
You should get a good CPU AIO
Find one that fits your CPU and if installed correctly your CPU tenps will max out at 60 even under turbo frequencies not taking into account crazy extreme overclockings

It shows in bios voltage tab that it only changes dram voltage when I enable XMP.
I probably will not buy a liquid cooler, but if you or somebody could recommend some good air cooler, I might get that.
And as far as I know for this CPU, that isn't dangerously hot if its not running at that temp 24/7. Even the PTC is set to 95°C as default, but I still would want it to be a bit lower.

My thoughts exactly
CPU can tolerate high temps no doubt even higher than that of GPUs but i got an AIO day one for my gaming pc which has a 8700k and now i feel so much relaxed seeing it sit at 30 degrees on idle at around 4400 to 4600 mhz
So in my opinion a 60 to 70 dollar worth of AIO wouldnt be a bad idea
If you wouldnt want to go for the AIO anyway i would simply readjust all the airflows and make sure they are pulling the case heat out of the casing efficiently thats all thats going to keep your system allrite

Before you go splashing out on new coolers and things, just open the side of your case and see how the temperatures perform.
It may just be that you have a crap air flow through the case.
Cheaper to remove the side of the case, than to buy a new cooler at this moment,
Then if that works, look at upgrading air flow coolers, again cheaper than a new cooler.

That definitely lowered the temps a lot, CPU was around 60-70°C with highest peak to 74°C and GPU was 55-60°C. My next question would be then that how can I make the air flow better? I have 3 fans at the front and 1 at the back. There is 2 more spots at the roof and I have already ordered those 2 fans a while ago, should be getting them soon. But I asked some weeks ago in here that would it make any difference to my temps if I add those 2 extra fans to my case, and the answer was "not much". So is there anything else I can do to make the air flow better?

It sound like you have enough fans maybe an extra exhaust could help, In my opinion it sounds like the case and restriction of airflow in the case, what case are you running?

 

[ivictori]

40 to 55 is the idle temperature achieved from stock coolers of cpu and as mentiomed already now you can concentrate on exhausting the hot air away from your case

 

[ElectrO_90]

Maybe you will have to put the 2 at the top in Exhaust mode, instead of blowing in cold air mode.
You can try both, obviously and see which one is better.

what case are you running?

Kolink Horizon RGB, like said in the first post.

Alright, gonna try these when I get those fans, thx for help.

I got my fans now and installed the first one without problems, but the second one I didn't install yet since it would be contacted to this part of the MOBO.

So I was wondering will it be a problem?

Just a small update that the temps seems to be fine now.

First I added one more exhaust fan to the top of the case, but that had no affect temps reached 80°C in 10mins on game play.

After that I added another exhaust to the top, so now there was 3 intakes at the front, 1 exhaust at the back and 2 exhaust at the top. That did help, but not enough. Temps reached 80°C after 30mins of playing.

Then I tried to change one of the roofs exhaust fan to intake fan, like in the picture at the bottom. And that seemed to help, 1 hour playing and CPU temp was going between 58°C - 72°C with highest peak to 75°C. GPU temp were 66°C. So far looks good so thanks all for the help!

I have the fans like this right now.
