5.4 System Fans

Four 60x38-mm fans and an embedded fan for each installed power supply, provide the primary airflow for
the system. The system is designed for fan redundancy when configured with two power supply modules. If a
single fan fails (system fan or power supply fan), platform management will adjust the airflow of the
remaining fans and manage other platform features to maintain system thermals. Fan redundancy is lost if
more than one fan is in a failed state.
The system fan assembly is designed for ease of use and supports several features:
Each fan is hot-swappable.

Each fan is designed for tool-less insertion and extraction from the fan assembly. For instructions on

installing or removing a fan module, see the Intel
Fan speed for each fan is controlled by integrated platform management controlled by the PDB.

When system thermals fluctuate high and low, the PDB firmware will increase or decrease the speeds
of specific fans within the fan assembly to regulate system thermals.
Each fan has a tachometer signal that allows the PDB to monitor its status.

On top of each fan is an integrated fan fault LED, which will turn on when a fan failure occurs.

Each fan has a 10-pin wire harness that connects to a matching connector on the PDB.
