i struggle with the roon server using a lot of power all the time, sometimes heating up my nuc to 80+ degrees celsius.
i have tried restarting the server which causes the server to struggle to find my wiim ultra and pro, and ive also tried reindexing the library twice, which fixes the issue, but only for a little while until it starts going off again
the issue has been merely annoying for a while, but now i struggle to use my roonserver. it is slow and stops playing music often.
Describe your network setup
I have a 500mb/s speed up and down fiber connection. my apartment is 50 square meters and the main units i use for playback including my roon server is wired connection
How old is the NUC?
When was the last time is was taken apart to clean?
Is it sitting on some other piece of gear that is getting warm?
Is the airflow good to the unit?
If it is older, it may need new thermal paste?
From what you’ve described, it sounds like your NUC is overheating after cleaning, which points more toward a hardware issue rather than Roon itself. Roon normally doesn’t use heavy CPU unless you are running DSP features, EQs, upsampling, or multiple zones simultaneously. Simply running the core and playing to a few zones shouldn’t push a NUC from 2016 anywhere near 80°C.
Since you already cleaned it, it may be worth having a professional check the thermal paste and the cooling system to ensure everything is applied and seated correctly. This is a delicate process, and doing it yourself can sometimes make the problem worse.
Switching to Roon ROCK might simplify the OS side, but it won’t fix an underlying hardware/thermal issue.
