✎Due to the adhesive quality of the thermal material located between the fan/heat sink assembly and
system board components, it may be necessary to move the fan/heat sink assembly from side to side to
detach the assembly.
✎
The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink assembly and the system
board each time the fan/heat sink assembly is removed. Thermal material is applied to the UMA fan/heat sink
assembly to correspond with components on the system board as follows: the processor
1
and the Northbridge
chip
2
. Replacement thermal material is included with all system board, fan/heat sink assembly, and processor
spare part kits.
