A bit of fishing around turns this up: https://gist.github.com/bakman2/e801f342aaa7cade62d7bd54fd3eabd8 If the sensor/fan controller chip in your laptop is indeed one of the it87 models, you will need either the out-of-tree kernel module recommended on that page, or maybe just a quite recent kernel—the it87 chip on my mobo (completely different model from a completely different manufacturer, though) is supported in-tree as of kernel 6.1. I was using the out-of-tree module during 2018-2022, and it was touchy and required a boot param to allow it to load despite an ACPI conflict (that might have been fixed, though.)
