XPS 730(X) H2C cable pinout (work in progress)

thermistor
| S1 | S2 | S3 |
The thermistor feeds into MCB to turn on/off +12V on the two red wires.
The TEC is hard coded to only turn on when temps rise above a certain amount and it's 100% load.
each TEC is 40x40 mm, which is industry standard size. the ceramic cooler is a 40x80mm block on each side, with 4x TECs, 2 per side. two TEC connected in series refers to the 2 TEC on the same side, each getting +6V. the TEC's on opposite side are completely separate electrically. that is why there are two +12V red wires, one for each side.
