How do I install and use iCUE software with the Corsair Harpoon?
Applies to: Corsair Harpoon RGB Wireless Optical Gaming Mouse
Last updated: September 2025
Problem
The Corsair Harpoon Wireless Mouse works without software, but advanced features such as DPI adjustments, button remapping, lighting effects, and profiles require Corsair’s iCUE software. Without iCUE, you won’t be able to unlock the full customization options of the mouse.
Solution
You can install iCUE on Windows or macOS, then use it to configure the Corsair Harpoon Wireless Mouse for personalized gaming and productivity.
Step-by-step instructions
Installing iCUE
- Go to the Corsair official website and navigate to the iCUE download page.
- Download the latest version of iCUE software for your operating system.
- Run the installer and follow the on-screen instructions.
- Restart your PC if prompted.
Connecting your mouse to iCUE
5. Connect the Corsair Harpoon to your PC via USB cable, dongle, or Bluetooth.
6. Open the iCUE software — the mouse should appear in the device list.
Customizing settings
7. Select the Harpoon Wireless Mouse in iCUE.
8. Adjust DPI levels (set up multiple sensitivity stages).
9. Remap mouse buttons to different actions, macros, or shortcuts.
10. Change RGB lighting effects and brightness (if your model supports it).
11. Set polling rate and other performance options.
Creating and managing profiles
12. Create game-specific profiles with different DPI and button mappings.
13. Save profiles to your PC or directly to the mouse’s onboard memory.
14. Switch between profiles manually or let iCUE switch them automatically when launching games.
Optional methods or tools
- Onboard profiles: Store settings directly on the mouse for use without iCUE installed.
- Macros: Record complex key combinations for one-click execution.
- Profile sharing: Download or import profiles from the Corsair community.
Best practices or tips
- Keep iCUE updated to ensure compatibility and access to new features.
- Use onboard memory if you want your settings to carry over when using the mouse on another PC.
- Create a default everyday profile and separate ones for gaming genres (e.g., FPS, MMO).
- Avoid setting overly complex macros that may conflict with system shortcuts.
