ALIX.1E has schematics available. W83627HF has specifications available too.
>From the W83627HF one can see there are 3 ports for temperature monitoring: PIN# | PURPOSE | FUNCTION 102 | VTIN3 | Temperature sensor 3 input (used for CPU2 temperature) 103 | VTIN2 | Temperature sensor 2 input (used for CPU1 temperature) 104 | VTIN1 | Temperature sensor 1 input (used for system temperature) >From the ALIX.1E schematics, page 10, there is only PIN# 104 connected, from those enumerated, the rest are not. Unless they are using another way to measure temperatures (which i didn't checked on schematics), there is only one temperature monitored. As for the place the input is connected, it looks like it goes to the LX memory controller. So it must be the temperature of the board itself, more or less. Same goes for voltages. I think you can address this issue to pcengines support, they are generally very responsive.
