Processor Installation
As a supplement to the manual provided with the boxed processor, install the processor and fan heatsink in the following manner. Open the processor socket handle (see Figure 12) and carefully align the processor using the pin one markings on the processor and socket for reference (Be careful not to bend any of the processor pins.). The processor pin one marking on the substrate of the FC-PGA2 package should be aligned with pin one mark on the socket (Figure 13). Insert the processor into the socket and close the socket handle.

Use the following instructions for installing the fan heatsink:
- The boxed Intel Pentium 4 processor will have thermal interface
material attached to the bottom of the heatsink shown in Figure 15
(Be careful not to damage the thermal interface material.) or
included in an applicator (Figure 15). If included in an applicator
with the boxed processor, apply all of the thermal interface
material to the center of the processor's integrated heat spreader
(see Figure 15).
- Align the fan heatsink and clip assembly (A in Figure 14) with
the retention mechanism (the fan heatsink is symmetrical) and place
it on the processor (as shown in Figure 15). Allow the heatsink
base to compress (without rotating or twisting) the thermal
interface material over the surface of the processor's integrated
heat spreader.
- With the clip levers (C in Figure 14) in the upward position,
push down on all four clip frame corners (D in Figure 14) to secure
the clip frame latches (E in Figure 14) to the retention mechanism
hooks (F in Figure 14), as shown in Figure 16.
Note: Make sure the processor fan cable is free from any obstruction and is not trapped under clip frame (B in Figure 14).
-
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
processor will operate correctly. Follow these steps, for closing
the clip levers and ensuring the thermal interface material is not
damaged:
- 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 17a. First, close the clip lever (1 in Figure 17b), while holding the topside of the fan heatsink with your other hand (A in Figure 17b).
- Then, close the clip lever (2 in Figure 17c), while holding the topside of the fan heatsink with your other hand (B in Figure 17c).
- 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.
- Lastly, connect the processor fan cable to the motherboard fan
power header (Figure 18). Consult the motherboard manual to
determine the correct fan header to use.
