Capability
Senses the air temperature at the trailing edge of the board.
Assumes air direction from the PMC slots toward the
processor/heatsink.
Senses a diode temperature in the processor junction.
Senses the air temperature at the leading edge of the board under
the solder-side cover. Assumes air direction from the PMC slots
toward the processor/heatsink.
