In-Depth Information
To install the CPU cooler, align the tips of its four posts with the four mounting
holes in the motherboard. The four mounting posts/holes form a square, so you
can orient the CPU cooler in any of the four possible positions and still mount it
successfully. We recommend positioning the CPU cooler so that the power cable
for the CPU fan reaches the connector on the motherboard with minimum cable
slack. Once you have the four posts and holes aligned, press down firmly on one
post, as shown in Figure 4-28, until you feel it snap into place.
Ron Morse Comments
The Intel-supplied CPU cooler uses
a variable-speed fan with a four-
pin power connector. The system
controls the fan's operating speed
(and the amount of noise it makes) in
concert with the operating tem-
perature of the CPU. Make sure you
connect the CPU fan to the four-pin
header on the motherboard labeled
“CPU FAN.”
After you have snapped all four posts into place, you need to lock them. The top
of each CPU cooler post has an arrow to indicate which direction to turn it to
lock the post into place. Figure 4-28 shows the cap of a CPU post before it has
been twisted to the locked position. You can use your fingers to turn the posts
to the locked position, but it's easier to use a flat-blade screwdriver, as shown in
Figure 4-29. Lock all four of the posts. Figure 4-30 shows a cap in locked position.
The final step in installing the CPU cooler is to connect the CPU fan power
cable to the CPU fan power header pins on the edge of the motherboard, as
shown in Figure 4-31. Make sure the keys on the connector bodies match, and
then slide the connector onto the pins until it seats.
