Processor Cooling Shrouds
Your system contains up to two processor cooling shrouds with fans to direct air flow over the processor(s). If your system contains two processor cooling
shrouds, you must remove the cooling shroud for CPU_1 before you can remove the cooling shroud for CPU_0.
If only one processor is installed (CPU_0), a fan blank must be installed in place of the CPU_1 fan to maintain proper cooling.
Removing the Processor Cooling Shrouds
1. Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
2. Open the system. See " Opening the System " in "Troubleshooting Your System."
3. If two processor cooling shrouds are installed, disconnect the fan's power cable for CPU_1 from the system board. See Figure A -3 .
If only one processor cooling shroud is installed, disconnect the fan's power cable for CPU_0 from the system board. Proceed to step 5 .
4. Press the cooling shroud's locking tab and the lift the CPU_1 cooling shroud up slightly. See Figure 6 -1 .
5. While squeezing the two shroud release levers that secure the cooling shroud to the back of the chassis, lift the shroud up and out of the chassis. See
Figure 6 -1
Figure 6-1. Removing and Installing the Processor Cooling Shrouds
CAUTION: Only trained service technicians are authorized to open the system cover and access any of the components inside the system. See
your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against
electrostatic discharge.
NOTICE: To avoid damaging the fan power cables, do not remove the shroud too quickly.
NOTE: If there are two processor cooling shrouds installed, you must remove the CPU_1 cooling shroud first.
