I/O Shield Cooling System The SC810 chassis has an innovative cooling design that includes a 10-cm blower system cooling (intake) fan and one optional 4-cm fan that can be installed in the midsection of the chassis.
The blower fan plugs into a chassis fan header on the motherboard and operates at full rpm continu- ously. If it breaks down, the ambient air temperature inside the chassis will rise and activate an overheat LED. 1-3
