System Features
Cooling Fans
Each power supply has built in cooling fans that pull cool air in from the front of the
chassis. Two chassis cooling fans pull cool air in from the front of the chassis and blow it
across the node board heatsinks and memory DIMMs. The chassis cooling fans receive
power from the node board assembly (refer to
Figure 2-6).
The graphics card assembly has its own cooling fan and heatsink assembly. The warm air
is discharged out of the rear panel of the chassis (refer to
Figure 2-13).
