Boxed Processor Specifications

7.1.2

Boxed Processor Fan Heatsink Weight

The boxed processor fan heatsink will not weigh more than 450 grams. See Chapter 5 and the

Intel® Pentium® 4 Processor on 90 nm Process in the 775-Land Package Thermal 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.
