Hello, new to the forum.
First off: I've tried searching for the subject already, and can find others with this issue through google,
although they're running Plex and actually saying that the problem doesn't occur in Jellyfin and Emby.
So I just installed a Quadro P2000 yesterday in my TrueNAS Scale server running Jellyfin from the TrueNAS "app store".
I quickly noticed that after ending a transcode stream, the GPU fan goes straight to around 75-80%.
Weird thing is, that before I started the transcode AND during the transcode, the fan is running quiet.
It's only when I end a transcode that the fan goes nuts. When I start a new transcode the fan slows down again.
According to ChatGPT it's because of limitations in the nvidia driver - blaming it on TrueNAS Scale not having an x-server running?
It suggested I tried playing around with the ASPM and PCI-E power management settings in BIOS/UEFI,
but setting everything to "L0sL1" made the GRUB bootloader freeze. So I set whatever I could to "auto" instead.
nvidia-smi output after a transcoded has been stopped for 20 minutes:
https://pastebin.com/7wYMYJ1n
If I run this command:
"nvidia-smi --loop=1 --query-gpu=fan.speed,temperature.gpu,pstate --format=csv"
The GPU drops in fan speed, and after a while changes power state to first P5, and then P8.
So it seems that whenever the GPU is left on it's own, it goes into some kind of panic mode?
ChatGPT suggested a workaround where I "poke" the driver with a set time interval,
but I'm not sure what to think about that.
Has anyone else had this problem?
Has anyone found a solution?
The server is located in my living room, so the 80% fan speed is very noticeable and annoying..
Thank you in advance.
Sincerely, JellyMango.
EDIT:
Maybe it's worth noting, that I have set the primary displayer adapter to CPU in the BIOS/UEFI.
So TrueNAS is outputting it's terminal through that.
