Attach the Heat Sink Mount to the Side Panel
A key step before replacing the top panel is the attachment and adjustment of the Heat Sink Mount (HSM) to the side panel. As noted earlier it can pivot/move,
which changes the space between it and the side panel. For optimal performance it must be correctly positioned to make good contact with the side panel.
With the HSM still in the up position, replace the side panel and lock it in place with the thumbscrew. Push the HSM downwards until it makes firm contact with the
side panel. The heat pipes should still have a slight upward angle away from the GPU and be applying pressure on the HSM to force it against the side panel . Fit a
universal bracket to the frame making sure it aligns with the holes on the opposite side of where the heat pipes enter the HSM. Note that the HSM can be adjusted
to the left or right to ensure the bracket clears the motherboard tray and aligns with the screw hole on the HSM. The bracket will lock the HSM in place and apply
additional pressure to ensure positive contact with the side panel. A thumbscrew can also be used to lock the HSM in place and stop it from moving. If done
correctly, the gap between the HSM and side panel should be parallel which indicates that even force is being applied along the length of the HSM.
The GPU cooler part of the installation is now complete and the rest of DB4 assembly can be followed as detailed in the main user guide.
