What is it?

MBProbe is a program which monitors voltages, temperatures and fan speeds using hardware monitoring chip(s) available on many modern motherboards. Its features include:

  • Up to 9 voltage, 4 temperature and 3 fan speed readings (subject to the limitations of hardware monitoring chip(s) present).
  • Automatic detection of monitoring chips.
  • Small memory footprint.
  • Setting of nominal voltage and fan speeds with warning thresholds.
  • Setting of temperature warning limits and offset readings.
  • Setting of sensor used for each temperature reading.
  • Temperature display in Celsius or Fahrenheit.
  • Customisable task when critical temperature is exceeded for more than 30 seconds continuously.
  • Ignores fan warnings for 10 seconds after system comes out of suspend.
  • Swappable temperature display in status icon on taskbar.
  • Motherboard Probe also offers Event and history logs.


  • Microsoft Windows 95, 98, ME, NT 4.0 or Windows 2000
  • Motherboard with hardware monitoring capability
  • Supports motherboards multiple temperature-only monitoring chips (SMBus)
  • Chipset with SMBus host controller (required for SMBus monitoring chips)
  • Optional thermistors to measure temperature (for Winbond chips)
  • Optional FanTemp to measure temperature using fan inputs
