> Battery life is also much better. The fan itself is obviously eating less power. I think the CPU also enters a somewhat lower power state in whisper mode, or it’s willing to sleep a little deeper. It’s not clear everything that changes, and it varies by machine, but that’s the beauty of it. You can get 90% of the way here on an Intel CPU by setting the EPB. There are a number of ways to do this on Linux: https://wiki.archlinux.org/title/CPU_frequency_scaling#Intel_performance_and_energy_bias_hint https://wiki.archlinux.org/title/CPU_frequency_scaling#Intel... By shifting to a more power efficient mode, the fan noise should be lowered or eliminated (the fan in my laptop is default off and it rarely comes on at all).
