Cooling fan specications
The cooling fans are integrated into the system to dissipate the heat generated by the functioning of the system. These fans provide
cooling for the processors, expansion cards, and memory modules.
Your system supports a total of eight fans, including six hot-swappable fans and two external fans. Two hot-swappable fans are mounted in
rear side of the air shroud. The other four hot-swappable (middle) fans are mounted in the fan assembly that is located in the chassis
between the hard drive bay and the processors. The two external fans are mounted on the outside of the chassis for GPU congurations.
There are two additional fans integrated in the power supplies to cool the power supplies and provide additional cooling for the whole
system.
