thermald is good for ordinary users I guess. I hate those things though. I disabled all of those thermal and laptop mode management daemons on my Fedora laptop. I ran a CPU stress while manually tweaking the Intel RAPL settings until I found the 80C limit and just set that on boot. I also wrote into the boot scripts the powertop settings that I liked. Even without RAPL settings the laptop won't fry itself. You can see the machine check events in dmesg as the CPU hits 90-95C and throttles.

I thought CPUs and GPUs throttled themselves to keep the thermals safe?

  You're right. I had a W520 Thinkpad that would shut off if it got too hot and wouldn't enter to BIOS until it cooled. (Probably is true of many laptops; that one seemed to frequently overheat on me during intensive, prolonged compilations.)

    Open the laptop up and reapply the thermal paste. It dries up over time as it gets exposed to higher temperatures, and then you get constant overheating problems as the heatsink can no longer cool the CPU effectively.

  Safe for the CPU is a pretty low bar: the Tjunction of their latest mobile CPUs is 100°C, and I'm pretty sure most users would not be very happy with using a laptop at that temperature.

    Some laptop models (particularly the more "fruity" ones) get awfully close to that Tjunction number. Close enough that there's most likely a decent case that the hardware is taking quite a bit of actual wear and tear from those temperatures.

    Have you used a Macbook? Because they will happily get to 99C before their fans are even at 100%.

Thermald is relatively new (Intel made) fan modulation system designed mostly to (1) keep boost frequencies running as long as possible. (2) keep your fan from constantly turning off and on. Your system has its own fan speed curve & power envelope that works no matter what the system is doing. Not having thermald does not somehow cause your system to overheat (for example many AMD systems aren't support) Turning thermald off is Intel signally that they have an on-silicon/in-kernel/in-EFI/partner guidance method that now does as equal or better job.
