Cooling System
The The SC743S1-R760 chassis has an innovative cooling design that includes
four 8-cm hot-plug system cooling fans located in the middle section of the chas-
sis and two 8-cm hot-plug rear exhaust fans. Each power supply module also
includes a cooling fan. An air shroud, which directs the airfl ow to the areas of
highest heat build-up, is also included. All chassis and power supply fans operate
continuously.
A setting in BIOS (see p. 7-18) is used to control the system fan speed. This setting
uses voltage control to allow fans to run at different speeds. [The recommended
setting is “4-pin (Server)”.]
