Thermals And Cooling; System Fans And Airflow Direction - Onlogic Axial AC101 Product Manual

4 - Thermals and Cooling

The Axial AC101 Edge Server is designed to operate and function across a wide temperature (5 to
40°C) and humidity range (8 to 85% RH non-condensing). The following sections describe the
thermals and cooling capabilities and behavior of the system.

4.1 - System Fans and Airflow Direction

The Axial AC101 Edge Server has five 40x40x56mm counter rotating system fans, which can be
independently controlled and configured via the Baseboard Management Controller (BMC) relative to
the supported system temperature sensors. The default fan duty and configuration settings have
been validated to operate in accordance with the supported temperature range (up to 40°C). If the
ambient operating temperature is tightly controlled, additional fan configuration optimizations may be
manually adjusted to optimize acoustics and reduce power consumption. For additional information
pertaining to manual fan configuration settings, please consult the Axial Edge Server BMC User
Guide.
The power supply fans operate independently and have their own closed-loop cooling algorithm.
