Set to be merged for the upcoming Linux 7.1 merge window is the "Yogafan" hardware monitoring driver to provide fan speed monitoring not only for Lenovo Yoga laptops but also various Legion and IdeaPad laptops too.
The Lenovo Yogafan driver will provide fan speed monitoring for Yoga, Legion, Flex, Slim, and IdeaPad laptops via interfaces exposed over ACPI with the Embedded Controller (EC) found on these laptops. Lenovo laptops rely on an EC interface over ACPI rather than LPC hardware monitoring chips or similar.
Some of the laptops tested so far include the Yoga 14cACN, Yoga 710/720, Yoga Pro 7/9, Yoga Slim 7, IdeaPad 5, Legion 5 AMD, Legion 7i Intel, LOQ 15/16, ThinkBook G6, Flex 5, and various pre-2020 models using a legacy interface.
More details on this new Yogafan driver can be found via [1]this patch queued up in the hardware monitoring subsystem (HWMON) "hwmon-next" Git branch ahead of the upcoming Linux 7.1 merge window.
