The same AsusFanControl.exe starts the GUI when you double‑click it or run it with no arguments, and runs command-line mode when you pass any CLI flag (for example AsusFanControl.exe --get-fan-speeds).
Command line (same executable)
AsusFanControl.exe <args>
--get-fan-speeds
--set-fan-speeds=0-100 (percent value, 0 for turning off test mode)
--get-fan-count
--get-fan-speed=fanId (comma separated)
--set-fan-speed=fanId:0-100 (comma separated, percent value, 0 for turning off test mode)
--get-cpu-temp
GUI: run AsusFanControl.exe with no arguments (it will automatically request admin rights).
My laptop does not support the Fan Profile option, but it often overheats. Looked for apps to control fans, but none is working.
This program should work on any laptop with x64 windows where Fan Diagnosis in MyASUS application is working as it is using same library.
ASUS System Control Interface is necessary for this software to work - ASUS System Analysis service must be running. It's automatically installed with MyASUS app.
The release build embeds the same AsusWinIO64.dll (licenced to (c) ASUSTek COMPUTER INC.) that you can find in C:\Windows\System32\DriverStore\FileRepository\asussci2.inf_amd64_-\ASUSSystemAnalysis\ if you have MyASUS installed; the DLL also remains in the repository under AsusFanControl.Core for the build.
- ASUS: VivoBook, ZenBook, TUF Gaming, ROG Strix, ROG Zephyrus, ROG Flow
Because this application interacts with hardware-level drivers via AsusWinIO64.dll, antivirus software such as Windows Defender might falsely flag it as malicious. If you experience this issue, please add the executable to your antivirus exclusions. (Alternatively, you can compile and code-sign the executable yourself to prevent false positives.)
