gpu_fan option to show percent for Nvidia cards

[luisalvarado]

Currently testing the latest compiled version of MangoHud

But for Nvidia cards like the 4070, 4090 or 5090, it shows the RPM by default. Was curious to know if there is an option to show the Percent version of it for Nvidia cards. Currently it shows as

[17314642]

Does nvidia-smi show fan percentage for these cards (4070, 4090, 5090)?

[luisalvarado]

Hi, it shows in percent.

I am also able to change the fan speed using a percent value as seen below if that helps (I use it on a script to set the fan speed depending on the temperature)

nvidia-settings -a "[gpu:0]/GPUFanControlState=1" nvidia-settings -a "[fan:0]/GPUTargetFanSpeed=50" nvidia-settings -a "[fan:1]/GPUTargetFanSpeed=50"

[17314642]

Can you compile mangohud with -Dwith_xnvctrl=disabled so mangohud will use only nvml for fan speed

Does it show in percent now?

[luisalvarado]

I did it like this

./build.sh build -Dwith_xnvctrl=disabled

but still shows with RPMs, maybe I am supposed to add the parameter somewhere else?

Also just noticed this warnings for future reference:

Did you clean build? When changing project options, you need to either clean build or reconfigure (i haven't tested that this works, so I just clean build)

[17314642]

And after that send logs with MANGOHUD_LOG_LEVEL=debug just in case

[flightlessmango]

If mangohud is compiled with and the system has nvctrl, fan option will prefer using RPM. We could just remove this since it only works with x11

[17314642]

nvml supports both fan rpm and percentages:

nvmlDeviceGetFanSpeedRPM nvmlDeviceGetFanSpeed

xnvctrl can be deleted in my opinion, since nvml, if i understand correctly, should be always available when using proprietary nvidia drivers

[flightlessmango]

I can't find the nvmlDeviceGetFanSpeedRPM function, are you sure it exists?

[17314642]

https://docs.nvidia.com/deploy/nvml-api/group__nvmlDeviceQueries.html

CTRL+F "fan"

[17314642]

What I didnt know, is that it is very recent addition (6 months ago):

https://docs.nvidia.com/deploy/nvml-api/change-log.html#change-log

Changes between v560 and v565

The following new functionality is exposed on NVIDIA display drivers version 565 Production or later. Added nvmlDeviceGetFanSpeedRPM to report the intended operating speed in rotations per minute (RPM) of the device's specified fan.

[luisalvarado]

Correct I did a clean, also did reconfigure and even deleted the whole folder. BTw that link is amazing, kudos on that finding, its a gold mine.

[17314642]

Mangohud uses nvml and xnvctrl libraries

Nvml is used for fan speed only in percentages Xnvctrl is used for fan speed only in rpm

That would mean that nvmlDeviceGetFanSpeed for some reason gets rpm and not percentage as it should.

Can you drop logs with MANGOHUD_LOG_LEVEL=debug?

[luisalvarado]

Sorry volcano activity here and breathing problems. Will get back later with this.

[luisalvarado]

How do I test MANGOHUD_LOG_LEVEL=debug @17314642

[17314642]

You launch mangohud with MANGOHUD_LOG_LEVEL=debug environment variable.

One way to do this: MANGOHUD_LOG_LEVEL=debug mangohud vkcube

[luisalvarado]

Would this work? MangoHUD did show properly just in case, but I see here it tried to look for the conf file in /usr/bin, /etc and even the kitchen sink, before getting to the correct one.

you have fan rpm because mangohud is using xnvctrl instead of nvml

Okay? And what parameter in mangohud would I use to tell it to use percent? Or is this a case where it is related to the compilation process and only 1 can be set (either percent or rpm)

[17314642]

currently you can't disable this, unless you compile without xnvctrl using option -Dwith_xnvctrl=disabled

[luisalvarado]

currently you can't disable this, unless you compile without xnvctrl using option -Dwith_xnvctrl=disabled

So if I compile without it, it would go to percent?

[17314642]

Yes

[luisalvarado]

Yes

Then buddy, I can close this ticket as solved. You answered everything like a gentleman. Thank you.

[flightlessmango]

We could probably add percent for AMD and make an option to select either one
