InstallingtheCPUcooler
The stock Intel DBX-B CPU cooler supplied with the Core i7-980X processor is
huge. With maximum power dissipation of 130W, it has to be. Because of its
size and weight, this CPU cooler requires a supporting bracket on the under-
side of the motherboard. (If you use a different processor, the stock CPU cooler
may mount via locking posts that don't require the support bracket.)
To begin installing the CPU cooler, loosen the four captive thumbscrews that
secure it to the support bracket, as shown in Figure 5-30.
Remove the support bracket and set it aside for now. Invert the CPU cooler
and peel off the protective plastic film that covers the heatsink base, as shown
in Figure 5-31.

Lift the edge of the motherboard nearest the CPU socket, and slide the sup-
port bracket under the motherboard. Position it so that all four of the threaded
hubs protrude though the mounting holes surrounding the processor socket.
Carefully lower the motherboard and verify that all four of the threaded hubs
are visible in the mounting holes. Position the CPU cooler over the threaded
hubs, with each captive thumbscrew resting on a hub. Press down on each
captive thumbscrew and tighten it, as shown in Figure 5-32. The thumbscrews
are spring-loaded, so finger-tight is sufficient to secure them.
The last step is to connect the CPU fan power cable to the CPU fan power head-
er pins on the motherboard, which are located near the rear-panel I/O connec-
tors. Align the keyed cable connector with the keyed motherboard connector,
and press the cable connector down until it fully seats on the motherboard
header pins, as shown in Figure 5-33.
