User’s Manual 2-7
The Intel ® Xeon™ processors require especially designed heatsink and
fan assembly to ensure optimum thermal condition and performance.
Make sure that the heatsink with fan assembly is properly installed on the
motherboard. A tilted or improperly installed heatsink with fan assembly
can cause damage to motherboard CPU socket and/or CPU. Follow these
steps to install the CPU heatsink and fan.
2.3.3 Installing the CPU heatsink with fan assembly
1. Place the heatsink and fan
assembly on top of the installed
CPU, making sure that it fits in the
screw holes of the heatsink
bracket found at the bottom of the
CPU socket. (The heatsink
bracket comes factory installed
with the motherboard.)
2. Tighten all four (4) screws. Make
sure all screws fit properly in
place.
Take caution in tightening
screws. Do not over-tighten
screws, doing so may damage
the motherboard!
TIP: Follow the sequence shown:
half-tighten the screw on one
corner of the heatsink and fan,
then the next screw on the other
corner and so on, making a cross
pattern. Repeat until all four
screws are tightened properly.
