I have a freshly installed 20.10 system running on a 2012 MacBook Air
(MBA 5,2) and it is completely silent and cold when being idle:
rbalint@chaos:~$ sudo cpupower frequency-info
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 800 MHz - 2.80 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 800 MHz and 2.80 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 915 MHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
2600 MHz max turbo 4 active cores
2600 MHz max turbo 3 active cores
2600 MHz max turbo 2 active cores
2800 MHz max turbo 1 active cores
@seb128, @juliank I'm not sure if there is anything to fix in the user space,
but please report which laptops you experienced issues with. Those may need
firmware/kernel fixes.
