2.11 Compute Module Fans

The cooling subsystem for the compute module consists of three 40 x 40 x 56 dual rotor fans.
These components provide the necessary cooling and airflow.

cooling. If one of the compute module fans fails, it is recommended to replace the failed fan as
soon as possible.
Fan speed may change
Each fan within the compute module can support multiple speeds.
automatically when any temperature sensor reading changes. The fan speed control algorithm
is programmed into the server board's BMC.
Each fan connector within the module supplies a tachometer signal that allows the BMC to
monitor the status of each fan. If one of the fans fails, the status LED on the server board will
light up.
The fan control signal is from the BMC on the mother board to the power docking board and
then is distributed to three sets of dual rotor fans. The expected maximum RPM is 25,000.

2.12 Air Duct

Each compute module requires the use of a transparent plastic air duct to direct airflow over
critical areas within the compute module. To maintain the necessary airflow, the air duct must
be properly installed. Before sliding the compute module into the chassis, make sure the air
duct is installed properly.
