You're giving me flashbacks to the stupid amount of time it took for me to identify a coil whine issue on my motherboard that gets worse when the CPU is in power saving mode. I 'worked around' the issue for the longest time by leaving covid based processing going on folding@home, which would force my CPU into turbo mode. Eventually I found out that if I disabled cstates, it mostly went away.
