Fan Configuration
The cooling sub-system of the Intel
fan and one power supply fan (the SC5299WS configuration has an additional 92-mm drive bay
fan). The 4-wire 120mm x 38mm fan provides cooling at the rear of the chassis by drawing fresh
air into the chassis from the front and exhausting warm air out the system. This fan is PWM
controlled. The server board monitors several temperature sensors and adjusts the duty cycle of
the PWM signal to drive the fan at the appropriate speed. The 92-mm drive bay fan for the
SC5299WS configuration and the optional hot-swap drive bay kit provides additional cooling to
the drive bay by drawing fresh air from the front of the chassis through the drive bay and
exhausting it into the PCI bay area.
Removal and insertion of the 120-mm or 92-mm fan can be done without tools. The power
supply fan assists in drawing air through the peripheral bay area, through the power supply and
exhausting it out the rear of the chassis. All versions of the Intel
E are optimized for server and workstation boards that have an active CPU heatsink solution.
If an optional hot-swap drive bay is installed, a 4-wire 92-mm fan is included with the mounting
bracket kit for installation onto the drive bay. This fan has a PWM circuit that allows the server
board to control the fan speed based on sensor readings of ambient temperature.
In addition to these pre-installed fans, locations for three additional fans are provided for
customized configurations. Intel does not provide order part numbers for these customizable fan
options. A 120-mm fan can be mounted to the chassis behind the PCI card guide and provide
additional cooling to the PCI card area; two 80-mm fans can be mounted at the front of the
chassis to the right of the hard drive bay opening to provide more cooling.
The front panel of the Intel
sensor for SIO control. Server boards that support SIO control may use the LM30 sensor to
adjust fan speeds according to air intake temperatures. Refer to the server board
documentation for configuring use of the front panel sensor.

Server Board Fan Control
The fans provided in the Intel
can be monitored by the server management subsystem for the Intel
S5000XVN and S5000VSA. See the specific server board Technical Product Specification for
details on how this feature works.
