Don't know if this is a bug or a documentation issue but the sensors on the Quadros seem to map to "Power Adjust Sensors" 1-4 and 5-8 rather than temperature sensors 5-8 and 9-12 as suggested in the manual (and the aquabus page in Aquasuite).
poweadjust sensor 1..4 == sensor 9..12
poweradjust 5..8 == sensor 12..16
multiple devices use the same ressources in the device.
