Sensor monitoring
The Sensor Monitoring dashboard provides a centralized view of your system status. Use the navigation panel on the left to switch between different hardware components. The Tools section at the bottom allows you to enable the In-Game Overlay or TrayMon for background monitoring.
The CPU section (shown above) displays real-time data for each core. You can toggle between Frequency, Voltage, Power, and Temperature views. Below the core grid, visual bars show Common metrics and Power sensors, followed by the static Specifications of your processor.
Monitor the power delivery system. This view shows detailed VRM properties, including current amperage and power consumption metrics.
View properties for all detected graphics adapters. The top blocks identify the installed GPUs.
Below, you can see real-time and static data such as core frequency, temperature, VRAM usage, memory type, and driver version. The application currently supports monitoring for Nvidia discrete GPUs and all iGPU (Integrated Graphics) models.
Inspect your memory configuration. The top section lists installed modules with their slot number, capacity, and bus width.
The Specifications area tracks real-time frequency, FCLK, SoC voltage, and SoC power. You can also view primary Timings and Advanced info, which includes the manufacturer name and module part numbers.
Check the detailed status of your battery. This section displays the charge level, wear level, and current power state (charging/discharging). It also provides recommendations for charging habits and battery replacement based on the health data.
Analyze how the processor manages power. This view repeats the Common metrics for context and adds a Power states section. It lists all available performance states (P-States) and highlights the currently active state.
Saku PowerMon Pro
This tool displays the raw sensor data reported directly by your device's SMU. It is primarily designed for troubleshooting. While you can use it to monitor specific values and tag them with your own notes, its main purpose is to help solve technical issues. If you encounter a problem, I might ask for a screenshot of this window to understand exactly how your system is behaving.
Cooler tweaking
- Download and install NBFC in "C:/" drive or use Install NBFC button
- Click on suggest button (button with question symbol) to see suggested configurations
- Choose configuration from list
- Set Cooler management option to Enabled

Settings
- Startup & Tray: Choose whether the application starts with Windows and how it minimizes (to the taskbar or system tray).
- Auto-apply: Automatically load your saved overclocking profile when the application starts. This eliminates the need to press "Apply" manually.
- Updates: Enable automatic checks for new versions.
- Reapply Options: Force the application to re-apply settings every few seconds. This is useful if the BIOS or vendor software tries to reset your custom values.
Configure how the application interacts with your system:
Personalize the interface. You can select from built-in themes or create a custom design. The settings allow you to adjust the transparency of the background image and the opacity of the darkening mask.
Set a custom background using a local file or a direct URL. The application supports GIF animations for dynamic backgrounds.
Monitor your hardware directly from the Windows system tray. TrayMon displays real-time data from selected sensors (such as temperature, frequency, or power) near the system clock. You can customize the font, colors, background.
View system metrics while gaming. This feature integrates with RivaTuner Statistics Server (RTSS) to draw an overlay on top of your game.
You can select which sensors to display, assign specific colors, and change text in labels. Advanced users can manually edit the overlay formatting code for precise control.
View the list of global hotkeys used for quick actions (like switching presets). You can enable or disable all hotkeys from this menu.

Saku Overclock is built using C#, utilizing WinUI 3 and the Windows App SDK to provide a modern, native Windows experience.
- ZenStates-Core: Powering the backend, this C# library handles communication with the System Management Unit (SMU) to access hidden optimization settings.
- Saku RTSS CLI: A custom C++ bridge that manages the In-Game Overlay, displaying real-time sensor data and FPS.
- NBFC (Notebook Fan Control): The engine responsible for managing fan speeds and custom cooling curves.
- PawnIO: A low-level driver ensuring universal hardware access for applying overclocking settings safely.
- inpoutx64: Essential library for direct memory access operations.
- Collapse Launcher: UI/UX components adapted to enhance the visual interface and user experience.
Saku Overclock works immediately after installation. You do not need technical expertise to use the application.
- Download the installer from the Releases page.
- Install the application.
- Launch Saku Overclock.
- During the first launch, a setup screen will help you personalize the experience.
- Choose a preset on the main dashboard (for example, "Maximum" or "Eco") and click the ▶ Apply.
- The system is now optimized.
Note: The application may ask to install the PawnIO driver on the first launch. This driver is safe and required for the application to communicate with the hardware. Please allow the installation.
Saku Overclock adapts to your requirements, whether you need a quick result or full control.
After the setup, the main dashboard displays real-time system monitoring and a list of presets. Select a preset and apply the settings to improve performance immediately. You do not need to configure anything else.
If you want to customize the settings, Saku Overclock offers advanced tools:
- Presets Management: View and edit profiles using simple visual sliders. This page helps you understand the effect of each preset.
- Overclock Page: Adjust specific power, thermal, current limits and processor behavior.
- Safety Limits: The application restricts values to safe ranges to prevent hardware damage.
- Smart Suggestions: The system analyzes your hardware and suggests stable values.
Once you find the best configuration, go to Settings. Enable Startup with OS and Auto-apply latest settings. The application will automatically optimize your device every time the system boots.
We prioritize the safety of your hardware. Follow these rules to ensure a stable experience.
When you create custom presets, do not maximize values immediately.
- Increase a value slightly (for example, add +5W to the power limit).
- Apply the setting.
- Test the system stability under load.
- If the system is stable, you can increase the value again.
After you apply a preset, check the Notification Center in the application.
- The notification confirms settings are applied.
- If a setting was not applied, the notification will explain the reason.
- The notification may provide a link to the FAQ or suggest disabling the incompatible option.
If you set values that are too high, the device may freeze or shut down. This is normal during the tuning process.
- Force Shutdown: Hold the power button on your device for 5–10 seconds until the screen turns off.
- Turn On: Power on the device.
- Try Again: By default, Saku Overclock does not apply settings on boot after crash. Your device will start with factory settings. You can open the application, lower the values in your preset, and try again.
If you encounter an issue or have a suggestion, please let us know.
We are currently in a critical phase: The V1.0 Release. Our primary focus is ensuring rock-solid stability for the core features.
Once the release settles, development will be driven by community feedback and polls. However, we already have some game-changing technologies on the horizon:
- OC Finder Next: The next evolution of our tuning algorithm. It won't just suggest settings; it will actively run stress tests and iteratively refine parameters to find the absolute peak performance for your specific silicon.
- Stream Stabilizer: A dynamic resource maneuvering engine. It adjusts CPU properties in real-time to ensure rock-solid frame times during streaming or heavy multitasking.
- Advanced Thermal Management: Full control over fan curves, including "Smart Curves" that adapt to your workflow.
- Preset Automation: Automatic preset switching based on power source (Battery vs. AC Adapter).
- English Support
- Community-contributed translations (Coming post-release)
