Removal and replacement procedures The following illustration shows the replacement thermal material locations for computer models equipped with graphics subsystems with discrete memory. ✎ The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink assembly and the system board components each time the fan/heat sink assembly is removed. Thermal grease is located on the section of the fan/heat sink assembly 1 that services the processor 3. A thermal pad is located on the section of the fan/heat sink assembly 2 that services the Northbridge chip 4. Replacement thermal grease and pads are included with all system board, fan/heat sink assembly, and processor spare part kits. Reverse this procedure to install the fan/heat sink assembly. 4-52 Maintenance and Service Guide
