158 Fan speed sensors can be accessed by selecting subfeature ``0x00``. The output data contains
159 up to four 16-bit fan speed readings in big-endian format. Most machines do not support all
160 four fan speed sensors, so the remaining reading are hardcoded to ``0x0000``.
164 RPM = 480000 / <fan speed reading>
166 If the fan speed reading is zero, then the fan RPM is zero too.

177 Reverse-Engineering the MSI WMI Platform interface
183 The underlying embedded controller interface is used by the ``msi-ec`` driver, and it seems
186 This means that the remaining WMI methods can be reverse-engineered by looking which part of

194 Special thanks go to github user `glpnk` for showing how to decode the fan speed readings.
