System Fans
System Fan Failure

Three 8-cm hot-swap fans provide the cooling for the system. It is very important that the chassis
top cover is properly installed and making a good seal in order for the cooling air to circulate
properly through the chassis and cool the components. See Figure 6-2.
Figure 6-2
Removing System Cooling Fans
Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans
will ramp up to full speed and the overheat/fan fail LED on the control panel will turn on. Replace
any failed fan at your earliest convenience with the same type and model (the system can continue
to run with a failed fan). Remove the top chassis cover while the system is still running to
determine which of the fans has failed.
