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

and the Dual-Core Intel

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. 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 

. 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.
