B.9 Local Air Thermocouple Placement
For passive heatsinks, two thermocouples will be placed 10 mm upstream of the processor heatsink.
The thermocouples will be centered with respect to the height of the heatsink fins and evenly across
the width of the heatsink.
For active heatsinks, four thermocouples will be placed on the fan inlet. These thermocouples will
be mounted between 5 mm and 10 mm above the fan. The average of these measurements will be
used to represent the local inlet temperature to the active heatsink.
