Not sure exactly what controls it, but at least I found out that there
is in the BIOS a setting for thermal management where I can choose
between "balanced" and "performance" (if memory serves) and which talks
And changing it did make a significant difference (I still can't
compile Emacs without triggering throttling, but it takes a lot longer
before it kicks in).
