System Fans
Eight heavy-duty fans provide cooling for the chassis. These fans circulate air
through the chassis as a means of lowering the chassis' internal temperature.
The chassis includes counter-rotating fans. Each fan unit is actually made up of two
fans joined back-to-back, which rotate in opposite directions. This counter-rotating
action generates exceptional airflow and works to dampen vibration levels.
Fan Numbering in the BIOS
In the unlikely event of a fan failure, the failed system fan can be identified through
the BIOS, by utilizing the fan numbering system shown below. These numbers are
also imprinted on the floor of the chassis.
