My Ryzen CPU got quite hot, and hence also loud, under sustained all-core workloads. The CPU boost doesn't bring that much performance in these workloads (but it does in gaming), so I made two Linux bash scripts.

One does the actual boosting, cpu-boost.sh: https://pastebin.com/K9YShNM6

The other uses Zenity as GUI wrapper so that this can be hooked into the start menu, cpu-boost-gui.sh: https://pastebin.com/X7rhZ8DV

Now I can change it on the fly, even via GUI. Thanks to some sudoers settings (see comments in the first script), I don't even need to enter a password. Obviously, this is only for personal machines, not advisable on servers.

Maybe someone else finds this useful.

    @mansur85 It really depends on which CPU it is. The mobile CPUs as well as the 3000-5000 desktop models with integrated iGPU (3x00G, 4x00G, 5x00G) use a monolithic die that is rather easy to cool.

    The other desktop parts from 3000-5000 as well as the new 7000 parts use a chiplet design that concentrates the heat a lot more. The 5800X in particular runs hot because it's also a 142W part, and the 5800X3D with its cache on top is even worse.

    The new 7000 lineup compounds these problems further with its stupidly thick heatspreader.

    Nice. Small but useful

    Small typo: in the alias comment for .bashrc of the first command, I forgot the closing '. Should be:

    alias cpu-boost='sudo /opt/cpu-boost/cpu-boost.sh'
