Removing/replacing the CPU
To replace the CPU cooling assembly
Note:
Before you install the cooling assembly, completely remove any thermal compound residue on the surface of the
CPU and the base of the heatsink, and then apply a fresh thermal compound square to the base of the heatsink. When
installing the thermal compound square, make sure to remove the plastic backing on both sides of the square. Avoid
creating any bubbles or wrinkles on the square. Bubbles and wrinkles reduce the heat-transfer efficiency of the cooling
assembly.

Prepare the CPU cooling assembly for installation.
•
Make sure that the motherboard is placed on a padded, static-free work surface.
•
Apply a fresh thermal compound square, as described in the note above.
•
Align the cooling assembly so that when it is installed, the fan cable easily reaches the CPU fan power connector
CPU FAN (J16) on the motherboard.
