Platform Environmental Control Interface (PECI)
The PECI interface is a proprietary single wire bus between the processor and the
chipset or other health monitoring device. At this time the digital thermal sensor is the
only data being transmitted. For an overview of the PECI interface, see
PECI Feature
Set Overview.
For additional information on the PECI, see the datasheet.
The PECI bus is available on pin G5 of the LGA 775 socket. Intel chipsets beginning
with the ICH8 have included PECI host controller. The PECI interface and the
Manageability Engine are key elements to the

.
Intel has worked with many vendors that provide fan speed control devices to provide
PECI host controllers. Consult the local representative for your preferred vendor for
their product plans and availability.
