Known problems and common questions

If you are running a standard desktop PC and Argus Monitor offers fan control options for your hardware and can also read fan speed values, then it is very likely that you have to correct the associated BIOS setting to be able to control your fans. Please enter your BIOS settings and change the fan control mode for every fan for which fan control is not working (set it either to Auto, PWM or DC as appropriate for your hardware). Then fan control should work as expected.
If this still does not work but you know other software that is able to offer fan control functionality for your hardware, then please feel free to contact us and we will see what we can add support for your hardware.
For most laptop and server hardware there is either currently no known method to access fan control functionality or those methods are kept under wraps by the OEMs. For those types of devices we unfortunately cannot offer fan control functionality.

Having the Asus AI Suite with its Asus services installed (and with the Argus Monitor setting "Asus ATK sensor support" active) could show additional sensors. They will show up in 2 different monitoring sources, one being the SuperIO chip where most sensors and fans are physically attached to (most probably a Nuvoton or ITE brand), the other one named "Asus Service".
You may want to copy the correct channel names from the Asus Service source to the channels on the SuperIO chip source. The Asus Service source is more precise, because when accessing the SuperIO chip it is not possible to retrieve the channel names that are printed on the mainboard by the manufacturer.
Fans on "Asus Service" are only readable, not controllable. This is a technical limitation imposed by the Asus Service. Usually we recommend to hide the duplicate channels on the Asus Service in the Argus Monitor configuration and only use the SuperIO chip channels. An exception to this are special temperature sensors like Asus T-Sensor; these are not connected to the SuperIO chip and only show up on the Asus Service.

A possible cause could be that most PWM controlled fans stay at the same low speed in the 0..25/30% range and accelerate above that threshold linearly. There are very few exceptions to this. This is true for PWM controlled fans (4-pin fan connection).
DC controlled fans (3-pin fan connection) will turn off if the mainboard can regulate the voltage at the fan header to zero when given a zero percent control command.

At the moment there is indeed no reset mechanism to reset Argus Monitor settings to the default values. A normal uninstall procedure is also designed to keep the settings intact, mostly because some of our users perform a uninstall before installing a new version and would otherwise lose their configuration.

If you are comfortable with using Regedit, the easiest way to remove the settings and get back to the defaults is to follow this procedure:
  • Terminate a running instance of Argus monitor
  • Open Regedit and rename or delete the registry key: HKEY_CURRENT_USER\SOFTWARE\Argotronic\Argus Monitor
  • Start Argus Monitor again and all settings should be reset do their default values

Our software license is not based on any subscription model. You purchase a license and - depending on the license you select - you get also all new versions for free that are released within the selected license period.
All those versions for which you once had a license will never expire and can be used without any further payment as long as you wish. There is no time limit and no need to purchase any more than the one year license if you are happy with the current functionality that Argus Monitor currently provides.
If you upgraded by accident to any version that is newer than the last version for which your license is valid, then you can download all older versions and install them over your current installation. It is advisable to in this case also disable the internal update check.

We understand the wish to get our software for free. But there are expenses we have to cover, like the required software certificate and our development tools. We also need to purchase different kind of hardware to be to add support for new devices like AIO coolers or SuperIO chips. We therefore cannot simply give Argus Monitor away for free.
As a small company, we are not able to offer regional pricing and therefore have to set one price that fits the whole world as best as possible. We would consider Argus Monitor to be rather inexpensive where we are located, even though we understand that it might unfortunately seem more expensive where you live.
