If one fan fails, it does not affect the operation of the other fanThe cooling fans cool the CPU, main memory, and voltage regulators. The fans use either a push or pull configuration to move the air from the left side of the device to the right side of the device as shown in Figure 6.1.

•Total cooling capacity: 120 watts

•Total air flow: 80 LFM

•Fan operating noise: < 51 dB-A.
