Why does my system's PC speaker emit an alarm sounding like a police siren?
Many of our current products now include thermal monitoring that allows
the system to monitor the system and processor temperatures. If the temperature
of either the system or processor meets or exceeds the 'warning temperature' as
set in the CMOS setup (Chipset Features or Sensor & CPU Speed section) a
police-like sound will be broadcast out of the internal PC speaker.
Under normal stress the temperatures generally are found to maintain around 30 ~
55 degrees Celsius but may vary depending upon processor and system components.
I ever run AMD Athlon 1.2Ghz around 80 degrees, when its first release, the
CPU never burn but the system hang after an hour.
