solution and does not support variable voltage control or 3-pin PWM control. See 

 through 

 for details on the 4-pin active heat sink 

solution connectors. 

The fan power header on the baseboard must be positioned to allow the fan heat sink 
power cable to reach it. The fan power header identification and location must be 
documented in the suppliers platform documentation, or on the baseboard itself. The 
baseboard fan power header should be positioned within 177.8 mm [7 in.] from the 
center of the processor socket.

As previously stated the boxed processor will have three cooling solutions available. 
Each configuration will require unique design considerations. Meeting the processor’s 
temperature specifications is also the function of the thermal design of the entire 
system, and ultimately the responsibility of the system integrator. The processor 
temperature specifications are found in 

 of this document.
