Lower Fan Board
The lower fan board provides cooling for the lower half of the system. The Fan Board provides
main 12V to lower seven 40x56mm dual rotor hot swap system fans. The board also provides
the SMB interface for lower system fan monitoring and control, and provides power to the slim
line DVD and 2x 2.5" SATA SSDs. Each fan has its own fan bracket which includes fan LED
facing out of the front of the chassis. Additionally each fan has one PWM, two tachometer, one
presence signal, 12V power, and ground. The board also provides SMB fan speed monitoring or
control circuitry for seven 40mm dual rotor system fans (14 fan tachometers, 7 fan presence,
and 7 fan fault LED signals).
