4. Apply the proper amount of thermal compound to the CPU die and place
the heatsink on top of the CPU. Make sure the heatsink sits completely flat
on the CPU - if not, the space between the two will degrade the heat
dissipation function of the heatsink, which may cause the processor to
overheat.
5. Secure the heatsink by locking the retention clips into position. When
correctly installed, the clips should *click* into place and the three black
tabs on the CPU retention pieces should protrude fully through the corre-
sponding holes on the retention clips. See Figure 5-2 for a diagram of the
heatsink installation procedure.
6. Connect the fan wires to the rpespective CPU Fan cheader on the
motherboard. If installing two processors, repeat these steps to install the
second processor in the CPU #2 slot.
IMPORTANT! Please note that special, new silver heatsink retention clips must
be used with all Xeon 533 MHz FSB (front side bus) 604-pin processors.
These new retention clips have "604P" clearly marked on them. Using the old
clips will not keep the proper amount of pressure applied and may cause the
processor to overheat. You should not use these new retention clips with
Xeon 400 MHz FSB processors (even if the CPU socket is 604-pin) as they will
too tight and damage the CPU socket.
