The thermal engine monitors the temperature readings from all sensors.
For each sensor, five threshold temperatures can be set:
1. Low fan speed.
2. High fan speed.
3. SMI warning.
4. Shutdown CPU.
5. Shutdown everything we can.
Each of these thresholds can be set to either a fixed value or disabled.
Currently the real implementation of SMI warning and shutting down is
left as TODO, as indicated in the comment.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
