Boxed Processor Specifications
7.2.2
Boxed Processor Fan Heatsink Weight
The boxed processor fan heatsink will not weigh more than 450 grams. See
and the appropriate Thermal and Mechanical Design Guidelines (See
) for
details on the processor weight and heatsink requirements.
7.2.3
Boxed Processor Retention Mechanism and Heatsink
Attach Clip Assembly
The boxed processor thermal solution requires a heatsink attach clip assembly, to
secure the processor and fan heatsink in the baseboard socket. The boxed processor
will ship with the heatsink attach clip assembly.

Electrical Requirements
7.3.1
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
. Baseboards
contains specifications for the input and output signals at the fan heatsink connector.
The fan heatsink outputs a SENSE signal, which is an open- collector output that pulses
at a rate of 2 pulses per fan revolution. A baseboard pull-up resistor provides V
OH
to
match the system board-mounted fan speed monitor 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.
The fan heatsink receives a PWM signal from the motherboard from the 4th pin of the
connector labeled as CONTROL.
The boxed processor's fanheat sink requires a constant +12 V supplied to pin 2 and
does not support variable voltage control or 3-pin PWM control.
