D3000 Disk Enclosure User Guide (734753-001, March 2014)

Fan module
Fan modules provide cooling necessary to maintain proper operating temperature within the
controller enclosure.
If one fan fails, the system still runs, but HP recommends replacing the module. If two fans fail
(either one complete module, or one fan per module) the system shuts down.
