Reference Design: Heatsink
FC-PGA with the reference
FC-PGA with a PPGA heatsink
CPU Insertion
Intel's reference design thermal solution is an
active heatsink; an extruded aluminum heatsink
base and a fan attached to the top on the fin
array.
•
Heatsinks for the PPGA will not work with the
FC-PGA. A pedestal is required on the
underside of the heatsink to clear the socket
cam box
Recommended thermal interface
material: Chomerics* XTS454.
Step 1
Open the socket by raising the actuation lever.
Step 2
Insert the processor.
Ensure proper pin 1 orientation by aligning the FC-PGA
corner marking with the socket corner closest to the
actuation arm tip. The pin field is keyed to prevent mis-
oriented insertion.
Don't force processor into socket. If it does not go in easily,
check for mis-orientation and debris.
Make sure the processor is fully inserted into the socket
on all sides.
Step 3
Close the socket by lowering and locking the actuation lever.
