Installing A Fan/Heatsink
Position the fan/heatsink on the processor such that the air from
the side of the fan/heatsink will flow across the heat regulators on
the system board. See the figure below.
Clearance Requirements
The processor comes with a heatsink mounted on top. To maintain
proper airflow once the upgrade is installed on the system board,
the processor and heatsink require certain space clearances. The
clearance above the processor’s fan/heatsink must be at least 0.4
inches. The clearance on at least 3 of 4 sides of the processor and
heatsink must be at least 0.2 inches. All cables (for floppy drive, hard
drive, CD-ROM, etc.) must be routed clear of the processor and its
airspace.
Fan Exhaust
The processor must be kept cool by using a fan with heatsink. The
temperature of the air entering the fan/heatsink cannot exceed
45
o
C (113
o
F). The ambient or room temperature must be below
37
o
C (99
o
F).
