Fan Heatsink Power Supply
The boxed processor's fan heatsink requires a +12 V power supply. An attached fan power cable
will be shipped with the boxed processor to draw power from a power header on the baseboard.

input and output signals at the fan heatsink connector.
The fan heatsink outputs a SENSE signal that is an open-collector output that pulses at a rate of
2 pulses per fan revolution. A baseboard pull-up resistor provides V
