The fans in the Intel® Server Chassis SC5400 are designed for server boards that support fan
control via a PWM control signal.

4.4.1
Basic Fan Control (All fans)
The front panel of the chassis has an active temperature sensor (i.e., Texas Instruments*
TMP141) connected to the front panel’s bus. Based on this front panel inlet temperature and
processor temperatures, the server board’s firmware will adjust the fan speed.

Additional Fan Control (120mm fans)
Fan control will monitor the temperature of the processors and further reduce the speed of the
120mm fans. This allows the system to provide minimal airflow for when processors and sitting
idle, then ramp fans speeds faster when they are under a heavy load. This will maintain proper
system cooling of all components and peripherals, while minimizing the acoustic noise level.
Refer to the baseboard documentation for additional details on how fan control is implemented.
