With a cooler installed and all cores loaded, the CPU frequency doesn't switch to 1800

If you want to pin M1 to 1.8GHz you can do this:

echo 1 > /sys/devices/system/cpu/cpufreq/boost
echo userspace > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
echo 1800000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed

Or if you want to make it persistent:

echo -e '#!/bin/bash\necho 1 > /sys/devices/system/cpu/cpufreq/boost\necho userspace > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor\necho performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor' | sudo tee /etc/rc.local && sudo chmod +x /etc/rc.local && sudo /etc/rc.local && cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

As I mentioned earlier, I manually switched the processor frequency.

I’m currently trying to figure out what needs to be done to automatically switch the frequency, with a cooler installed, between idle and load modes, such as compiling a program from source code. That is, when no such operations are taking place, the frequency should automatically return to 1600 GHz, and when the load returns, say, when launching an AI model, the frequency should increase back to 1800 GHz. The cooling system should also turn on and select the appropriate RPM depending on the load on the processor, and then turn off when there is no load.
