Cooling fans

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 up to six high performance hot swappable cooling fans.
For single processor systems without a mid drive tray, only four cooling fans are required. Fan bays 1 and 2 are covered by a fan blank.
NOTE: Each fan is listed in the systems management software, referenced by the respective fan number. If there is a problem
with a particular fan, you can easily identify and replace the proper fan by noting the fan numbers on the cooling fan assembly.
