There aren’t any standard ways to get this. Most of the mechanisms to
expose fan speed are within vendor-specific management suites.

Temperature, however, is exposed in most laptops via ACPI, which is in turn
exposed by WMI.

The “ACPI Fan” devnode exists even on Pentium 3/i815 mobos of 2000 vintage,
it does not work with WMI though :slight_smile:

The well-known fan speed measurer is Motherboard Monitor by some Dutch guy,
it uses the DLPortIO driver to work.
