The fan heatsink receives a PWM signal from the motherboard from the 4

th

 pin of the connector 

labeled as CONTROL. 

The boxed processor’s fan heatsink 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. 

 shows the location of the fan power 

connector relative to the processor socket. The baseboard power header should be positioned 
within 4.33 inches from the center of the processor socket.

1. Baseboard should pull this pin up to 5 V with a resistor.
2. Open Drain Type, Pulse Width Modulated.
3. Fan will have a pull-up resistor to 4.75 V, maximum 5.25 V.
