This is better addressed on the processor's end, as even if you "throttle" a process, your CPU is still going to turbo to a noisy state. In fact, it could make energy efficency worse by encouraging the CPU to run at higher clocks in short bursts (whereas it runs at slower, more efficient clocks during long constant loads). How you do this depends on the OS and CPU. RyzenAdj, for instance, works on AMD processors on linux and windows.
