Installation Tips for the LGA3647 Socket

Document Scope

There are several potential pitfalls a user can encounter while installing a CPU and heatsink into a LGA3647 socket. This article provides information on how to avoid many of the aforementioned pitfalls. A detailed installation guide is included alongside tips and illustrations of the LGA3647 Socket. 

Step 1: Proper Orientation

Ensure that the CPU is oriented properly before placing it on the pins. If the CPU becomes attached to the heat sink during installation, please ensure that the CPU's orientation does not change as the heatsink may not provide the correct orientation markers. 

Step 2: Careful Handling

Once the orientation is determined to be correct, DO NOT trust the plastic bracket to hold the CPU in the correct orientation. Please handle the CPU carefully as it could easily fall out of orientation. Install the heatsink/CPU combo into the socket or place the CPU in the socket first followed by the heatsink.

Step 3: Installation Order

Here is the critical part, follow the pattern indicated on most heatsinks. This would be starting with the screws on the corners and securing them all the way down. When moving onto the screws in the middle on both sides, please, screw one down roughly 50% before screwing the remaining screw down 50%. Then finish screwing #3 in and lastly #4.

Following the steps above allows the cooler to be as flush as possible with the CPU. Additionally, the gradual tightening of the screws allows the thermal paste to be spread evenly across the CPU's lid.

Additionally, the amount of torque used should be fairly substantial. This does not mean to set the highest torque on your electric drill (if using one) or wrenching it down with all your might but sufficient solid force should be used to ensure proper contact. The design of the socket will not allow for over tightening but damage can occur if excessive force is used.
