Boxed Processor
Requirements
6.3.1.
FAN/HEATSINK POWER SUPPLY
The Boxed processor’s fan/heatsink requires a +12 V
power supply. A fan power cable will be shipped with
the Boxed processor to draw power from a power
header on the motherboard. The power cable
connector and pinout are shown in Figure 48.
Motherboards must provide a matched power header
to support the Boxed processor. Table 29 contains
specifications for the input and output signals at the
fan/heatsink connector. The cable length will be 7.0
inches (±0.25"). The fan/heatsink outputs a SENSE
signal, which is an open-collector output, that pulses
at a rate of two pulses per fan revolution. A
motherboard pull-up resistor provides V
OH
to match
the
motherboard-mounted
requirements, if applicable. Use of the SENSE signal
is optional. If the SENSE signal is not used, pin 3 of
the connector should be tied to GND.
