High CPU temperature

I install Endeavour a week ago. Is my first Linux OS, so i can miss some things

Te issue: When im ok Desktop, usinf firefox or somethig not demanding, my CPU go arround 40-50°

When i launch a Game, the CPU spike yo 80-85°, but the usage wont pass the 60%

IDK if its hardware or not, i just swap to a r5 7600X

Anything that could help i answer as soon as i can

Actually using:

KDE Plasma
AMD P-State

Specs: Desktop PC
CPU: R5 7600X
GPU RX 6600
Motherboard: Asus RogStrix B650E
Cooler (Might be important) Cooler Master Hyper 212 RGB

I am already using amd p-state, wont this be in conflict?

Not knowing what you mean by “this”?

You could read around and find out… :wink:

you have to use pstate … not only enable it… :slight_smile:

i do use cpupower on my AMD could be also TLP is an easy to use option… as default power-profiles-daemon is not doing the best on AMD CPU systems.

I am reading about TLP And some other things i have installed like gamemod, might be in trouble if i install them together :frowning:

pstate is enabled in the Grub whith this command line:

 "GRUB_CMDLINE_LINUX_DEFAULT=“iommu=pt amd_pstate=passive processor.max_cstate=5*

idk if i have to do more configs

In the other hand, i would like to get the “best performance” whithout reaching that absurd thermals XD.

Thanks for the help btw, i try both <3

using a governor (CPUPOWER) will be a good option… or something like thermald what will try keeping temps low…

try changing to active (available since Kernel 6.3) and set the default behaviour to power or balance_power - power stands for powersaving here opposed to performance on the other side of the scale. Details on how to do that can be found here:

with that, and AMD ECO Mode activated in BIOS, I get very good temperature readings on my 7700X that are only above 80° when compiling stuff with a Alpenföhn Brocken 3 air cooler - no other config changes made.

Edit: I totally forgot that I also apply a dynamic undervolting on all cores with the AMD Curve Optimizer in BIOS. The values one can reach there heavily depend on the individual hardware lottery, and one could get more out of it when applying per core values, but I don’t have the time and all core -32 works fine here. (64 is max)

i will try it as soon as i get back home, and update whith the results

I dont have sys/devices/system/cpu/cpufreq/policy0/energy_performance_preference XD
Maybe i messed up something

CPU Usage usually indicates total usage across all cores while temperature is usually highest single core temperature so high temps while seemingly “low” CPU usage is normal. Most of the replies here are for power saving when idle / low activity but you get high temps while gaming so I don’t think these suggestions will help. You can look into limiting FPS, lowering down game settings or setting fans to maximum.

I know it might get a “high” temperature, but 5ººº below the max temp after shotdown… it not seems fine to me

What I meant is that you can get high temps even if your CPU usage is %10 or %100 because all it takes is a single core to go full blast and reach high temps.

changing to active p-state and setting it to power or balance_power influences all work loads, not just idle.

Post your grub_cmdline from after editing it. Did you regenerate the grub config after editing?

That depends on the game setting. If you do not limit FPS and enable ultra setting (it requires a lot of calculations by CPU and GPU), that would cause high temperature when you play for a long time.

You need a good cooling for PC.

That is by design and should be a normal behaviour. As far as I was able to find. There is no target frequency when CPU goes to boost mode but there is a target thermal limit ~85˚C.

There are some reviews of 7000 series - youtube, tomshardware

I have Ryzen 9 7900 and it does the same thing. Well, actually it doesn’t since it hits 85W power limit before the temperature can go any higher (I like to keep the power consumption low which also keeps the cooler quiet). Interestingly when all 12 cores (24 threads) run at 100% load the temperature is around 65˚C at 4.8GHz but when only 2 cores run at full load the temperature is 80˚C at 5.4GHz. Also, undervolting helped significantly to drop power consumption and increased clock frequency.


It was the thing.

I found several articles talking about how AMD tells reaching 95º its “normal temps” (which I totally disagree with)
The thing was: I swap my CPU and decide “i’m gonna run a linux on this” so i was convinced it was my fault messing up something, and don’t find anything about this until yesterday, when a friend told me about that and change the focus to the hardware.

Reaserching a bit more drive me to some guides on how to limit the TDP and set a power target into the bios to a reasonable 85ºC, + changing the curve optimizer to -15.
Here is a how to video on an ASUS bios
Fix to Ryzen 7000 high temps

With that done, and following the BS86 advice (High CPU temperature - #10 by BS86) i achieved to low the temps from:

  • 50º on desktop - 85 gaming to
  • 36º on desktop - 65 / 70º gaming.

That was a lot more reasonable (and idc losing 10fps of performance, or waiting one more second to open things)

Thank you all guys for helping me. I left this here in case anyone have the same problem.

I also do not feel like that is normal or good but I could not find a strong evidence why is it a problem - just a feeling. Somewhere, I read that this is exactly what graphic cards do and they are working just fine.
As far as I can tell the high temperature has an effect on the power consumption and perhaps a “wear” of the cpu (I upgrade abpout every 6 years so I hope it will be fine for so long).
And the cpu is so far doing just fine. There is no thermal throttling - the frequency of the cpu is stable at the higher temperature and there is no drop in a performance over time.

Since I locked my cpu to 85 W max power and I have more than sufficient cooler the temperatures are reasonable between 60-80˚C at 100% load (depending cores used and clock speed). The tepmerature is very closely related to the power consumption (and performance). You can limit the power but it may influence the performance as well.
A good way to reduce the power consumption (and temperature) with the same performance is undervolting - if your cpu has a good quality silicone.
