The mainboard page is divided into three sub pages.

The first sub page 'Fan Speed' contains a graph which displays the fan speeds of all fans connected to the appropriate mainboard fan connectors.

The second page 'Fan Control' offers the possibility to control the speed of the system fans if supported by the mainboard Super IO chip. Depending on mainboard vendor and model not all channels might be available for fan speed control.

Fan speed can be controlled manually or by a graphical temperature-fan speed characteristic. With the graphical characteristic, any temperature source (from the temperature sources recognised by Argus Monitor) can be selected.

For each fan controlled in this way, current fan speed, current percent value of the control preset and temperature of selected temperature source will be displayed:

Please note that it's not possible to control the fan speeds between 0% and 20% to ensure a safe start up of the fans.

If you want to apply the last fan speed setting on each start of Argus Monitor, you find the corresponding option in Settings / Mainboard (see picture below).

The valid control range for the manual fan speed setting is between 20% and 100% of the maximum fan speed, exceptions are notebooks manufactured by DELL and Lenovo Thinkpads:

Lenovo/IBM Thinkpads:

  • 8 different fan speed settings are available
  • Setting 0 turns the fan off, settings 1-7 set constant fan speeds with increasing number of rotations per minute.

DELL Notebooks:

  • 3 different fan speed settings available
  • Setting 0 enables the BIOS fan speed controller, settings 1-2 set constant fan speeds with increasing number of rotations per minute.

To provide each fan and temperature channel with an unique name there is a specific option in Settings / Mainboard. It is also possible to prevent fan and temperature channels from showing up in the respective graphs:
