3.4 Installing the Fan Heatsink
Use the following instructions for installing the fan heatsink:
1. The heatsink has thermal interface material attached to the bottom, shown in
Figure 3-7. Be careful not to damage the thermal interface material.
2. Align the fan heatsink and clip assembly (A in Figure 3-6) with the retention
mechanism (the fan heatsink is symmetrical) and place it on the processor (as
shown in Figure 3-7). Allow the heatsink base to compress (without rotating or
twisting) the thermal interface material over the surface of the processor's inte-
grated heat spreader.
3. With the clip levers (C in Figure 3-6) in the upward position, push down on all
four clip frame corners (D in Figure 3-6) to secure the clip frame latches (E in
Figure 3-6) to the retention mechanism hooks (F in Figure 3-6), as shown in Figure
3-8.
Note: Make sure the processor fan cable is free from any obstruction and is not
trapped under clip frame (B in Figure 3-6).
4. Note: It is important to not allow the heatsink to rotate or twist on the
processor's integrated heat spreader. Securing the fan heatsink while closing the
clip levers will ensure the thermal interface material is not damaged and the pro-
cessor will operate correctly. Follow these steps, for closing the clip levers and
ensuring the thermal interface material is not damaged:
a. ) Make sure to close the clips levers in opposing directions, one at a time
(levers require force to be completely closed), as shown in Figure 3-9a. First, close
the clip lever (1 in Figure 3-9b), while holding the topside of the fan heatsink with
your other hand (A in Figure 3-9b).
b. ) Then, close the clip lever (2 in Figure 3-9c), while holding the topside of the
fan heatsink with your other hand (B in Figure 3-9c).
5. Once the clip levers are closed, verify that the heatsink is securely retained and
that the clip frame latches are properly engaged with the retention mechanism
hooks.
Note: When installed, the fan heatsink and clip assembly may cause the
motherboard to slightly bend or flex. This provides the proper mechanical support
for the processor (with attached fan heatsink and clip assembly) and helps prevent
against damage during system shipment.
