LB440GX 2U Rack Server Chassis TPS Rev 1.0
4 Chassis Cooling
Two system fans and the power supply fan provide cooling for the processor(s), hard drives, and
add-in cards. Two 80mm system fans are mounted in the middle of the chassis. All chassis fans
provide a single tachometer output for RPM detection that the server board can make available for
server management monitoring and alert functions. Removal of the top cover gives access to the
fans, which then can be easily changed with the system powered down.
