I am using plex for some days to stream from my pc to my LG oled 55c1 but I’ve noticed my cpu going warm when using it for watching 4k videos. I took a pass and activated the hardware acceleration but that didn’t seemed to fix it. I have a 5900x and I’m on W11.
Thanks for the help
It is normal that a busy CPU is getting warm. Transcoding video for 90 minutes will make a CPU pretty much constantly busy.
It is the task of the computer manufacturer to make sure that the heat can be dissipated quick enough.
If your computer has a cooling system which can’t handle a constantly loaded CPU, it is not suitable as a Plex server.
Temperature were around 60 to 70c, is this normal?
If the CPU is loaded 100%? Yes, that’s actually quite good. These CPU’s are specced for even higher temps.
But of course the cooler you can run them, the longer they are going to last.
If you want it to run cooler, you need to modify the cooling system.
i.e. build it yourself, use a bigger case, use “overclocker” coolers etc.
I never see my cpu going above 70 anyways even when encoding videos or heavy tasking except stress tests of course
I have a 360 aio from Ek temps are good but the plex transcoder seems to warm the gpu very fast, I wanted to know if some settings could help.
All-in-one devices are not really great as servers with heavy computing load.
There is nothing you can do.
Except transcode less. e.g. by using client devices/client software which can play your files as they are.
I guess it’s all good and safe then thanks
