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

 and the 

Guidelines for details on the processor weight and heatsink requirements.

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. 

The boxed processor's fan heatsink requires a +12 V power supply. An attached 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 

. Baseboards must provide a 

matched power header to support the boxed processor. 

 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

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.
