Fans Module
The fans module contains four 48V fans, which can dissipate heat for systems
up to 270W. The fans draw air into one side of the chassis, and push the air
through the chassis and out the other side.
Fans Module Detailed View
The fan speed increases and decreases in response to the temperature inside
the chassis. When the temperature rises, the fan speed increases, and when
the temperature decreases, the fan speed decreases. The fan speed never
decreases below a minimum level regardless of temperature.
