As the processor gets hotter, internal clocks and so on are throttled within the hardware to try and stabilise the temperature (to keep the thermal trip point being reached, re: "emergency shutdown"), which greatly decreases performance. I'm not sure if there's a way to detect this, but I would h

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. a bit of hunting found you

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. Can you, by any

The specified maximum CPU temperature is usually the same at the ACPI _CRT, not _PSV. That is the temperature when an ACPI shutdown should be triggered, but TCC should kick in at some point below this. This laptop is a replacement for an earlier one that had similar overheating issues. On that
