I have a Clevo M760TUN. As with
this, it only has one fan cooling both the CPU and GPU.
The fan support in ACPI is very poor, so I turned to RWEverything, and found this thread...
My system fits in well with what has already been mentioned. My guess is that all Clevo laptops use a very similar (and basic...) BIOS, or at least EC program.
D0/D1 is presumably fan speed, it changes often.
D2/D3 is 00/00
0A/0B is temperature (TMP) in 10ths Kelvin
Other temperatures:
04/05 is AC0 (~fan speed high)
06/07 is PSV (~throttle processor)
08/09 is CRT (~overheat shutdown)
0C/0D is AC1 (~fan speed low)
Remember that these are in the EC, rather than ACPI per se. Changing them didn't seem to have any affect. CRT, PSV and TMP are read as-is in their equivalent TZ methods, and there aren't any other temps in the TZ. From an old official ACPI doc: "One of the traps first-time ACPI developers can fall into is to not use all the objects in the \_TZ scope that are required to carry out their thermal policy..." then it gives 10 different things a proper TZ should have, of which my BIOS has 4... I guess things may have changed since then, but it's still poor. There's no fan-related stuff at all either.
CE-D3 (the area with the fan speed) is skipped entirely by the ACPI memory map, so reading that through ACPI wouldn't be easy. Setting FAN0/1 didn't affect the fan, but they didn't seem to reflect the current status either.
Someone else made an attempt at decoding their EC memory map
here (but not entirely right, AC in AC1 is Active Cooling rather than Alternating Current, I guess his BIOS/OS changes that when disconnected).
If you want to try deciphering yours (mine was very similar to his, so probably most Clevos use this), I can tell you where to find it.
