Graphic card gets hot
My GPU is RTX 3080Ti.
Previously I have two monitors: 4k@60hz + 2k@165hz, and the graphic card is just cold almost anytime, the fans on it don't even work (except when I play 3D games).
But today I add the third monitor: 1080p@60hz, it starts getting hot and the fan start working... at first I think it is the third monitor adds more works to the GPU, so I turn the 2k@165hz monitor to 60hz, but I found that it does not helps, the fan is still working and graphic card still gets hot?
why is that, I think turn 2k@165hz to 60hz should reduce much more work than adding an 1080p@60hz, so it should be better than when I just have 2 monitors, isn't it?

Re: Graphic card gets hot
It's generally normal that cards tend to clock higher by default with more monitors, what does "gets hot" actually mean in verifiable numbers? Output of nvidia-smi ?

It is about 54-56C

Re: Graphic card gets hot
Multihead layouts will make the nvidia driver activating the full composition pipeline - do you get similar effects w/ two outputs but w/ ForceFullCompositionPipeline enabled?

https://wiki.archlinux.org/title/NVIDIA … en_tearing
I have checked in nvidia-settings, neither for two outputs nor three outputs enables ForceFullCompositionPipeline, so it might not be the reason?
for nvidia-smi, this is two monitor output:

Re: Graphic card gets hot
The driver doesn't activate that setting but the behavior that can be enforced by it - you're therefore supposed to test whether activating the setting (and enforcing the full composition pipeline) on the dualhead causes the same behavior that you see on the triple head.

I enabled full composition pipeline under 2 monitors, and nvidia-smi output like this:

Re: Graphic card gets hot
What if you set all three outputs in semi-clone mode (ie. have them all overlapping start at 0,0)?

If I stack those three all to (0,0), nothing changed in nvidia-smi.
But I try to make 1080p@60hz to 50hz, then the power decreased about 30W (from more than 90W to 64W)..... and temp reduced from about 55C to 48C...

Re: Graphic card gets hot
With the 2k at 165Hz or at 60Hz?
What'S the impact of sudpending the kwin compositor (SHIFT+Alt+F12)?

With 2k@60hz (but the previous 91W also with 60hz).
Pressing SHIFT+Alt+F12 it suddenly jump to 101W and flash then come to normal (as it not been pressed)

Re: Graphic card gets hot
You're not in persistence mode but the GPU doesn't get out of P0…
Check the powermizer setting in nvidia-settings and try to set the preferred mode to adaptive (it's likely? auto and the current mode is performance?)

I just checked, it is auto and the current mode is adaptive.
Also, I just tried Windows, it might be helpful (cause I intalled on another ssd on the desktop), with 4k@60+2k@60+1080p@60, nvidia-smi outputs like this:

Re: Graphic card gets hot
Could be a difference in the nvidia driver, could be plasma's bazillion GL contexts that keep the GPU in P5 and prevent P8 (feel free to try an openbox session)
Your main problem is however (apparently, given the data so far) that the chip moves from P5 to P0 and stays there when you add a 3rd output.
=> Try to force the performance mode to adaptive (instead of auto)

Re: Graphic card gets hot
You can try to limt the power demand and see whether that has notable performance impacts (you'll have to unlimit it when you want to play some game and you'll likely also notice it on browsers)
nvidia-smi -pl 35Next up:
1. do NOT rotate the outputs (any of them!) and check the impact
2. if that's still not doing anything, try to run an openbox session (or startx xterm) and see what the power demand is in that "clean" environment

It outputs like this
[...~]$ nvidia-smi -pl 35
Provided power limit 37.00 W is not a valid power limit which should be between 100.00 W and 400.00 W for GPU 00000000:01:00.0
Terminating early due to previous errors.Now, I am confused about (under 4k@60+2k@60+1080p@50):
1. the perf shown by nvidia-smi (currently P3)
2. the GPUCurrentPerfLevel by nvidia-settings -q (currently 4)
3. the performance levels shown in the UI of nvidia-settings (it has 0, 1, 2, 3, 4, and is set to 4 when I open the UI and then jump to 2)

Re: Graphic card gets hot
GPUCurrentPerfLevel is what you can see in the powermizer settings in nvidia-settings, not the P-mode. Lower values typically mean "less power demand" here.
Did you try the behavior w/o output rotation?

Re: Graphic card gets hot

Yes, without rotation the power dropped 3W (from 65W to 62W) and Volatile GPU-Util decreased from 6% to 1%, and nothing else changed.
and the code nvidia-smi -pl 35 still output the same message.

This will not change as the driver doesn't allow you to limit the power damand this much.
Since the rotated output isn't relevant, did you try an "startx xterm" session?

I am not sure what is startx xterm session, but tried the kde/openbox session, here is what I have done:
I install openbox by
sudo pacman -S openboxthen I reboot and in the login menu I choose kde/openboox option,
after I logged in I run nvidia-smi, the output is almost the same with before:

Re: Graphic card gets hot
Not "KDE/openbox" - no KDE.
https://wiki.archlinux.org/title/Xinit
http://wiki.archlinux.org/index.php/Sys … _boot_into - boot the multi-user.target, login there and run "startx" (make sure you've xterm installed)
You want to know whether the higher power state is triggered by the X11 server itself or somethingelse™ (plasma)

Just to make sure:
Should I run systemctl set-default multi-user.target, then reboot, then log in, then run startx.
And If I want to reverse back, should I run systemctl set-default graphical.target, then reboot?

Re: Graphic card gets hot
Alternatively, append one of the following kernel parameters to your bootloader:
systemd.unit=multi-user.target

Re: Graphic card gets hot
The wiki wrote:Alternatively, append one of the following kernel parameters to your bootloader:
systemd.unit=multi-user.target
I just did that, and after I logged in and run startx, it is like this https://ibb.co/qBTm317
where each of the white block is a terminal like this https://ibb.co/R4RQ8rh
and none of them is focused.... how can I focus to one of the block and type things?
Edit:
the mouse is extremely tiny, it took me a while to notice it...
anyway, the nvidia-smi output like this:
fan: 35% Temp: 55C Perf: P0 Power: 91W/350W Memory-Usage: 124MiB/12288Mib Volatile GPU-Util: 7%
