A modern, reliable, and feature-rich fan control utility for ASUS laptops, rebuilt from the ground up for stability, performance, and a polished user experience.
Zenith Fan Utility provides a comprehensive toolset to take full control of your laptop's cooling system.
- Custom Fan Curves: Create and switch between two distinct fan curve profiles for automated, temperature-based fan control.
- Interactive Curve Editor: A smooth, intuitive editor to add, remove, and drag points to define your perfect fan curve.
- Manual Control: Instantly take over with a simple slider, or use the "Max Speed" and "Fans Off" buttons for quick actions.
- Live Monitoring: Real-time display of CPU & GPU temperatures and fan RPMs, right on the main window.
- Hysteresis Control: Prevents annoying fan "flapping" by adding a configurable temperature buffer, ensuring fan speeds change smoothly.
- Configurable Refresh Rate: Adjust the stats refresh interval to your liking, from rapid updates to power-saving intervals.
- Polished Dark UI: A beautiful, custom-built dark theme that is DPI-aware, ensuring it looks sharp and crisp on modern high-resolution displays.
- Persistent Tray Icon: A G-Helper-style tray icon that provides live stats on hover and toggles the main window's visibility with a single click.
- Startup Ready: Configure the app to start automatically with Windows, minimized to the tray.
- Go to the Releases page.
- Download the
ZenithFanUtility_vX.X.X.zipfile from the latest release's Assets section. - Run
ZenithFanUtility.exe.
Important
It is highly recommended to run the application as an administrator to ensure it has the necessary permissions to control your system's hardware.
Warning
The latest versions of Asus System Control Interface (v3.1.41.0+) may restrict access to the driver required for manual fan control. If Zenith Fan Utility isn't working, you likely need to downgrade this driver.
Method 1: Roll Back the Driver (Recommended)
- Uninstall the latest Asus System Control Interface.
- Install a previous version, like v3.1.40.0.
- If Windows Update overrides it, go to
Device Manager -> System Devices -> Asus System Control Interface, then selectDriver -> Roll Back Driver.
Method 2: Run as SYSTEM Process (Advanced) If you are unable to roll back the driver, you can force the app to run with SYSTEM privileges.
- Download and extract PSTools.
- Place
PsExec.exeinto the same folder asZenithFanUtility.exe. - Run PowerShell as an Administrator in that folder and execute:
./psexec -i -s "$PWD\ZenithFanUtility.exe"
- Master Control: The "Enable Custom Fan Control" checkbox is the master switch. When checked, the app takes over your system's default fan behavior.
- Mode Selection: Use the radio buttons to switch between Manual Mode (slider is active), Fan Curve 1, or Fan Curve 2. When a fan curve is active, the manual slider is disabled.
- Tray Icon: The app lives in your system tray. A single left-click on the icon will show or hide the main window. Right-clicking provides options to show or exit the application completely.
This project was built to be a modern, stable fan control utility. It would not have been possible without the foundational work of several open-source developers:
- Karmel0x: Created the original proof-of-concept and the core library for hardware interaction.
- Pgian88: Provided a foundational update with many new features in a prior version.
- Darren80: Developed the original visual fan curve editor concept.
- BrightenedDay: Implemented the initial theming features.
