Boxed Processor Specifications

96 Dual-Core Intel® Xeon® Processor 3000 Series Datasheet

7.1 Mechanical Specifications

7.1.1 Boxed Processor Cooling Solution Dimensions

This section documents the mechanical specifications of the boxed processor. The

boxed processor will be shipped with an unattached fan heatsink. Figure 7-1 shows a

mechanical representation of the boxed processor.

Clearance is required around the fan heatsink to ensure unimpeded airflow for proper

cooling. The physical space requirements and dimensions for the boxed processor with

assembled fan heatsink are shown in Figure 7-2 (Side View), and Figure 7-3 (Top

View). The airspace requirements for the boxed processor fan heatsink must also be

incorporated into new baseboard and system designs. Airspace requirements are

shown in Figure 7-7 and Figure 7-8. Note that some figures have centerlines shown

(marked with alphabetic designations) to clarify relative dimensioning.

Notes:

1. Diagram does not show the attached hardware for the clip design and is provided only as a mechanical

representation.

7.1.2 Boxed Processor Fan Heatsink Weight

The boxed processor fan heatsink will not weigh more than 550 grams. See Chapter 5

and the Dual-Core Intel

Xeon

Processor 3000 Series Thermal and Mechanical Design

Guidelines for details on the processor weight and heatsink requirements.

7.1.3 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.

7.2 Electrical Requirements

7.2.1 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 that 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.

98 Dual-Core Intel® Xeon® Processor 3000 Series Datasheet

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.

The power header on the baseboard must be positioned to allow the fan heatsink power

cable to reach it. The power header identification and location should be documented in

the platform documentation, or on the system board itself. Figure 7-6 shows the

location of the fan power connector relative to the processor socket. The baseboard

power header should be positioned within 110 mm [4.33 inches] from the center of the

processor socket.
