Re: On-board temperature sensors

Robert, a motherboard with only a system temperature sensor (one that measures the temperature of the air in the case) is rather useless as compared to one which directly measures the temperature of the CPU (is in contact with or very close to the CPU or heat sink). The CPU could fry before the system temperature gets high enough to trigger an alarm. However, many motherboards which measure the system temperature also monitor the CPU fan, if the CPU fan is a "3-pin" fan and plugs into the motherboard. If an alarm condition can be set for a dead (0 RPMs) or slow CPU fan in either the CMOS or a Windows-based monitoring program such as Motherboard Monitor Lite (http://duxcw.com/digest/Reviews/Software/Utility/mbmon.htm) or Epox's USDM (http://duxcw.com/digest/Reviews/MBs/Epox/usdm.htm) then it should go-off before the CPU overheats. I have also seen hard disk drives get awfully hot without triggering a system heat alarm. Larry
