Running a multithreaded beets replaygain scan only utilises a single core which also keeps switching - so far odd that it only uses one core even though it has 9 threads and I told it to use 4 cores but whatever.
But then the fan regularly starts spinning, even though there is no heat.
The oddest part? Once I start stress-ng --cpu 8 the fan stops spinning despite an enormous rise in CPU usage

tlp and auto-cpufreq are already installed and active (systemd services) with default settings.

The power management inside the chips will let one core boost, but it’s likely that the OS moves to the next task in a way that’s not on the boosted core or that the heat management moves the hot spot across the CPU. Check you’re using the right command for beets replaygain, I guess.
