5. Setup and Installation
Follow these general steps for installing your Aigo AC SE liquid cooler. Refer to the included installation kit for specific brackets and screws for your CPU socket type.
- Prepare the CPU: Clean the CPU surface thoroughly. Apply a small amount of the provided thermal paste to the center of the CPU.
- Install the Backplate: Attach the appropriate backplate to the motherboard from behind, aligning it with the CPU socket holes.
- Mount the Water Block: Secure the water block (pump) onto the CPU using the correct Intel or AMD fasteners and screws from the installation kit. Ensure even pressure.
- Install Radiator and Fans: Mount the radiator to an available fan slot in your PC case (e.g., top, front, or rear). Attach the fans to the radiator using the fan screws, ensuring they are oriented for optimal airflow (intake or exhaust).
- Connect Cables:
- Connect the 3-pin pump cable to the CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the 4-pin fan cables to available fan headers on your motherboard. If using multiple fans, you may need a fan splitter (not always included).
- Connect the RGB cables to your motherboard's RGB header or a dedicated RGB controller if available.
- Cable Management: Route cables neatly to avoid interference with other components and to improve airflow.

6. Operating Instructions
The Aigo AC SE series coolers are designed for optimal performance with minimal user intervention.
- Automatic Fan Speed Control: The 12cm fans operate within an 800-1800 RPM range, adjusting speed based on CPU temperature via PWM (Pulse Width Modulation) control. This ensures higher airflow when needed and lower noise during light loads.
- Integrated RGB Lighting: The cooler features integrated RGB lighting on the fans and pump head. This can typically be controlled via your motherboard's RGB software (if compatible) or a dedicated controller (if included with your PC case or purchased separately).
- Efficient Cooling Design: The cooler incorporates an E-shape liquid channel design to enlarge the cooling area and improve circulation, a spraying type copper bottom for maximum contact with the CPU, and high-strength, leak-proof cooling pipes for reliable operation. The double pipe design of the water block ensures an unblocked channel effect.

7. Maintenance
The Aigo AC SE liquid cooler is designed to be maintenance-free regarding its liquid loop. The liquid is pre-filled and sealed, requiring no refilling or replacement throughout its lifespan.
- Dust Cleaning: Periodically clean the radiator fins and fan blades with compressed air to remove dust buildup. Dust can impede airflow and reduce cooling performance.
- Inspect Hoses: Occasionally check the cooling pipes for any signs of wear or damage. While designed for high strength and leak-proof operation, regular visual inspection is recommended.
- Fan Bearings: The fans use fluid dynamic bearings, which are designed for long life and quiet operation. No lubrication is required.
8. Troubleshooting
- No RGB Lighting: Ensure all RGB cables are securely connected to the motherboard's RGB header or a compatible controller. Check your motherboard's BIOS/UEFI settings or RGB software for control options.
- Fans Not Spinning/Pump Not Working: Verify that the fan (4-pin) and pump (3-pin) cables are correctly connected to the appropriate headers on your motherboard. Check BIOS/UEFI settings to ensure fan headers are enabled and configured correctly.
- High CPU Temperatures:
- Ensure the water block is securely mounted to the CPU with even pressure.
- Verify that thermal paste was applied correctly.
- Check for proper airflow in your PC case; ensure fans are oriented correctly (intake/exhaust).
- Clean any dust buildup on the radiator fins.
- Noise Issues: While designed for quiet operation, excessive noise might indicate:
- Loose fan screws.
- Dust buildup on fan blades.
- Pump noise (if audible, ensure it's securely mounted and not vibrating against the case).
9. User Tips
- Pre-filled Liquid: The liquid is already filled and sealed, so there's no need to add or replace it.
- Fan & Pump Connections: Connect the fans to 4-pin headers and the pump to a 3-pin header (often labeled CPU_FAN or AIO_PUMP) on your motherboard.
- Compatibility Check: Always double-check the supported CPU sockets (Intel LGA 1700/2066/2011-3/2011/1151/1150/1155/1156/1366/1200 and AMD AM4/FM2+/FM2/FM1/AM3+/AM3/AM2+/AM2) before purchase and installation.
