Intel® Quiet System Technology (Intel® QST)

Figure 24 shows the major connections for a typical implementation that can support

processors with digital thermal sensor or a thermal diode. In this configuration an

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

processor. With the proper configuration information, the ME can accommodate inputs

from PECI or SST for the processor socket. Additional SST sensors can be added to

monitor system thermal (see Appendix F 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.
