Intel® Quiet System Technology (Intel® QST)
Thermal and Mechanical Design Guidelines 61
Figure 22 shows the major connections for a typical implementation that can support
processors with digital thermal sensor or a thermal diode. In this configuration a SST
Thermal Sensor has been added to read the on-die thermal diode that is in all of the
processors in the 775-land LGA packages shipped before the Intel
®
Core™2 Duo. With
the proper configuration information the ME can be accommodate inputs from PECI or
SST for the processor socket. Additional SST sensors can be added to monitor system
thermal (see
Appendix E for BTX recommendations for placement).

Intel has engaged with a number of major manufacturers of thermal / voltage sensors
to provide devices for the SST bus. Contact your Intel Field Sales representative for
the current list of manufacturers and visit their web sites or local sales representatives
for a part suitable for your design.
