GL520SM Hardware Monitor
The Mainboard provides sophisticated hardware monitoring via
the on-board GL520SM integrated circuit. The GL520SM can be
used to monitor temperatures, power supply voltages, and fan
speeds and will generate interrupts and audible tones that allow
the system speaker to sound an alarm if it detects an abnormal
system situation. Through the SMBus software interface, the
host can program the temperature trip points and query the
GL520SM about system interrupt status, current temperature,
voltage, and fan speed.
