Airflow Requirements
The power supply incorporates two 40mm fans for self cooling and system cooling. The fans
provide no less than 10 CFM airflow through the power supply when installed in the system.
The cooling air enters the power module from the non-AC side.

Acoustics
6.3
The power supply provides cooling to both the supply and partially to the system. To meet
minimum system requirement, the power supply limits its acoustic sound pressure level not
exceed a noise level of 42-dBA measured at one meter on all faces @ 35°C ambient
temperature and 80% maximum output load. The two-speed fan control via analog fan
control complies with this specification. The power supply incorporates two 40mm fans for
self-cooling and system cooling located in the rear of the unit. Under a condition where inlet air
temperature exceeds the limit, sound pressure and sound power levels may exceed their limits.
