computer can play h.265 and equivalent without troubles, provided video file is no higher than 1080 p.
Computer can play av1 files no higher than 1080 p only if I shut every other application down. If for example I run a browser and an av1 file with either mpv or vlc, system shuts down.
Can I put all that memory to use and avoid overloading the cpu?
As others have said, you should probably replace your CPU fan ASAP.
A computer in usable condition does not shut down without user input.
