System Cooling
The system includes three replaceable 8-cm x 3.8-cm fans and shrouds to direct air flow.
Caution
: Since the system continues to draw a small amount of power in standby mode (and
fans are off), there is a potential for overheating if the system is idle for a long time. In this
situation, there is no warning from the overheat/fan fail LED.

8. Screw the fan brace on to the chassis using the screws previously set aside.
