6 Installing the heatsink to the socket
4
Start fastening the heatsink to the socket by tightening the outer
screws (number 1 & 2), starting with the screw at pin 1.
Then tighten the two center screws (number 3 & 4), starting with
the screw that is on the opposite side of pin 1:
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque
xx
Nm).
Remove the plastic dust cover from the CPU socket and put the
heatsink and CPU assembly onto the socket, aligning the CPU’s pin
1 indicator with the pin 1 indicator of the socket.
Verify that all the latches have snapped to the mounting brackets
and that the CPU and clip are fully attached to the heatsink.
Turn the heatsink upside down so that the base is facing upwards.
Carefully put it down onto the tips of the heatpipes and secure
it with your hand so that it cannot tilt and that the fins cannot
get bent. Remove the plastic protection cover from the base of the
heatsink and be careful not to damage the layer of pre-applied
thermal compound.
Caution: If you are not using the heatsink for the first time and
it therefore doesn’t have a fresh layer of pre-applied thermal
compound anymore, you need to apply a thin layer of thermal
compound to the CPU yourself before clipping it to the heatsink.
If there are residual traces of previous thermal paste or thermal
pads on your CPU or on the heatsink, please clean them off first.
Put the processor clip and CPU assembly onto the heatsink’s base
so that the posts of the clip go through the holes of the heatsink’s
mounting brackets. Push the clip towards the heatsink base until
the latches snap to the mounting brackets.
Caution: Some LGA3647 CPUs have a so called OmniPath fabric
connector. If your CPU is of this type, you need a different processor
clip. Please contact [email protected] if you have a CPU with
OmniPath fabric connector.
Orient the CPU so that the heatspreader is facing downwards and
the golden contacts are facing upwards. Be careful not to touch the
contacts. Then put the CPU into the clip, align the CPU’s pin 1
(golden triangle indicator) with the triangle pin 1 indicator of the
clip. Snap the CPU into the clip. Note that you may need to flex the
clip a bit for it to latch onto the CPU. Verify that the clip is fully
attached to the CPU before proceeding.
Put the clip upside down so that the long heatsink latches and posts
for heatsink alignment are facing downwards.
