System Cooling
The CSE-731I-404B includes a super quiet rear system fan that provides cooling for the
chassis. No tools or screws are required to install the system fan.
Under normal operation, the chassis fan and the power supply fan both run continuously.
If the chassis fan fails, the system must be powered down before replacing it. If the power
supply fan fails, the power supply itself must be replaced.
Replacing the System Fan
Begin by removing power from the system as described in section 3.1.
1.
Remove the left chassis cover as described in section 3-2.
2.
Insert the four rubber pins into the four mounting holes surrounding the fan grill on the
rear of the chassis.
3. Place the system fan on top of the fan grill, aligning the mounting holes of the fan grill
with the mounting holes of the system fan.
4. Pull the rubber pins through the mounting holes of the system fan to secure the fan to
the chassis.
