FYI for a new kernel mode sensor driver for ASUS motherboards with WMI BIOS'. The driver exposes all the BIOS sensor outputs to Linux just like it does in Windows. This driver replaces with much greater functionality the old it87 driver.

Right now it only works on kernels > 4.17 but the developer assures me that earlier kernels will be fixed shortly. This is what sensors exports on my ASUS Crosshair VII Hero motherboard.

Just a FYI update. The asus-wmi-sensors kernel mode driver now builds and installs correctly on kernel 4.15.0-43. The latest commit 587da84 was to "Remove use of hwmon_max so works on earlier kernel versions"

This is what is available now for reported sensors.

That can't be right. More than double the temp for boiling water....
Unless of course you're running your Computer on steam :-)

This is normal for a sensor header with nothing connected. From the repository Q&A section

Why do some of my temperatures return 216 deg C?
This is the value returned for temperature sensor headers with no sensor connected.
