Boxed Processor Specifications

7.2.2

Boxed Processor Fan Heatsink Weight

The boxed processor fan heatsink will not weigh more than 450 grams. See

Chapter 5

and the appropriate Thermal and Mechanical Design Guidelines (See

Section 1.2

) 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.

7.3

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

baseboard. The power cable connector and pinout are shown in

Figure 7-5

. Baseboards

must provide a matched power header to support the boxed processor.

Table 7-1

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

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.
