Clearance Requirements
Your 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 tem-
perature 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).
