5.5.6 Temperature Sensors
The SE7501WV2 server board has the ability to measure system and board temperature from a
variety of sources. The first is located inside the Heceta chip (U6G1) and is used to measure
the baseboard temperature. In addition, diodes located inside each processor are used by the
SE7501WV2 to monitor temperature at the processors. When installed in either the Intel
SR1300 or SR2300 server chassis, the SE7501WV2 also uses a temperature sensor on the
front panel to measure ambient temperature and will boost the fans depending on the reading it
receives from these sensors.
