I tried SpeedFan as a temperature monitor. It reports a cooler temp
than the bios.
How can a monitor get it's readings if it is not from the bios?
SpeedFan and the BIOS both get their readings from a hardware monitor
chip which has several inputs including temperature sensors (either
diode or thermistor), voltages, and fan tachos.
SF may report a lower temperature than the BIOS (mine does this)
because the OS may be cooling the CPU using Cool'n'Quiet, or PowerNow,
or SpeedStep, or a utility such as CPUidle.
