dev.cpu.X.freq does reflect the current frequency; I don't know whether
or how any internal clock throttling might be exposed.
From what I have seen, dev.cpu.X.freq always retains the value I set it
to. Internal CPU throttling does not seem to be reported this way.

I am not sure tz0 is the real thermal zone, especially given values
of _tc1, _tc2 and _tsp. Temperature value (3001) looks suspicious as
well.
I agree. tz0 looks entirely bogus. There is no second fan to control for
it and I have no idea what it is supposed to be monitoring.

If you boot into another operating system such as Linux or Windows, do
you see the same overall behaviour? Linux might be easier and might
have some built-in way to get at CPU temperatures (via /proc?).

I could be wrong, but in my experience this really sounds like it is

it was unlikely that Dell shipped a DSDT which leads to 0°C

temperatures) becomes extremely sluggish. As load (and temperatures)
drop, the system becomes usable again. Also, there is no difference
