Intel® Quiet System Technology (Intel® QST)
The ICH10 integrates four fan speed sensors (four TACH signals) and 3 fan speed controllers (three Pulse Width Modulator signals), which enables monitoring and controlling up to four fans on the system. With the new implementation of the single-wire Simple Serial Transport (SST) 1.0 bus and Platform Environmental Control Interface (PECI), the ICH10 provides an easy way to connect to SST-based thermal sensors and access the processor thermal data. In addition, coupled with the new sophisticated fan speed control algorithms, Intel® QST provides effective thermal and acoustic management for the platform.
