cooling.
Cooling fans
Servers use a lot of power to function, and that in turn generates a lot of heat. That heat, without a
system in place to dissipate it, can destroy the mechanical parts and damage the server. In most cases,
the simplest and most efficient way to dissipate this heat is through the use of fans.
Removing a cooling fan
WARNING: Do not attempt to operate the system without the cooling fans.
WARNING: The cooling fan can continue to spin for some time after the system has been
powered down. Allow time for the fan to stop spinning before removing it from the system.
