12.3.3 Fan Control<br />
The fans provided in the <strong>Intel</strong> ® Server Chassis P4000M Family contains a tachometer signal<br />
that can be monitored by the server management subsystem of the <strong>Intel</strong> ® Server Boards <strong>for</strong><br />
RPM (Revolutions per Minute) detection.<br />
The server board monitors several temperature sensors and adjusts the PWM (Pulse Width<br />
Modulated) signal to drive the fan at the appropriate speed.<br />
The front panel of the chassis has a digital temperature sensor connected to the server board<br />
through the front panel’s bus. The server board firmware adjusts the fan speed based on the<br />
front panel intake temperature and processor temperatures.<br />
Refer to the baseboard documentation <strong>for</strong> additional details on how fan control is<br />
implementation.<br />
12.3.4 Fan Header Connector Descriptions<br />
All system fan headers support pulse width modulated (PWM) fans <strong>for</strong> cooling the processors in<br />
the chassis. PWM fans have an improved RPM range (20% to 100% rated fan speed) when<br />
compared to voltage controlled fans.<br />
Fixed chassis fans are a 4-wire/4-pin style designed to plug into 4-pin or 6-pin SSI Fan headers.<br />
When plugged into a 6-pin header, only the first four signals are used (Pwr, Gnd, Tach,PWM).<br />
Hot-swap chassis fans are a 6-wire/6-pin style designed to plug into 6-pin headers. The extra<br />
signals provide <strong>for</strong> fan redundancy and failure indications (Pwr, Gnd, Tach, PWM, Presence,<br />
and Failure).<br />
