Cooling System
The SC825TQ-R700LP/SC825S2-R700LP chassis has an innovative cooling de-
sign that includes three 8-cm hot-plug system cooling fans located in the middle
section of the chassis. An air shroud channels the airfl ow from the system fans to
effi ciently cool the processor area of the system. The power supply module also
includes a cooling fan.
