H12SST-PS User's Manual
Un-installing the Processor and Heatsink
1. Remove the heatsink attached to the top of the CPU package by reversing the
installation procedure.
2. Clean the Thermal grease left by the heatsink on the CPU package lid to limit the risk of
it contaminating the CPU package land pads or contacts in the socket housing.
3. Reverse the procedure for installing the force frame onto the socket, unscrewing the
plate in the 3-2-1 screw order and lift the force frame to the vertical position.
4. Lift the rail frame using the lift tabs near the front end of the rail frame. Note that the rail
frame is spring loaded, so be careful lifting it up into a vertical position.
5. Grip the handle of the carrier frame and pull upwards to extract it from the rail frame.
Return the carrier frame/CPU package to its original shipping container.
6. Grip the handle on the external cap and return it to the rail frame sliding it downwards
till it rests in the frame.
7. Gripping the rail frame, rotate it downwards till it rests above and locks over the socket
housing in its horizontal position.
8. Push and rotate down the force frame till it is over the external cap and rail frame into a
horizontal position.
9. While holding down the force frame, secure it back to the socket frame by securing
screw 1 in place. Note that without a CPU package in place, it is not necessary to
tighten down screws 2 and 3 at this time.
