4. Setup and Installation
The Aigo ACSE liquid cooler is designed for easy installation on both Intel and AMD platforms. Please follow these general steps. Refer to the included user manual for detailed, step-by-step instructions specific to your CPU socket type.
4.1 Prepare Your System
- Power off your computer and disconnect all cables.
- Open your computer case.
- Remove any existing CPU cooler. Clean the CPU surface thoroughly of any old thermal paste.
4.2 Mount the Radiator and Fans
- Attach the 120mm fans to the radiator using the long fan screws provided. Ensure the fan direction is set for optimal airflow (typically exhausting air out of the case or drawing cool air in, depending on your case configuration). The fans feature a 9-blade design with anti-vibration pads for efficient and quiet operation.
- Mount the radiator assembly to an available fan mount location in your PC case (e.g., top, front, or rear).
4.3 Install the Water Block
- Identify the correct backplate and mounting brackets for your CPU socket (Intel or AMD) from the installation kit.
- Install the backplate behind your motherboard if required by your socket type.
- Attach the appropriate standoffs to the motherboard around the CPU socket.
- Apply a small amount of the provided thermal paste to the center of your CPU's integrated heat spreader (IHS). The cooler features a spraying type copper bottom to maximize contact area and speed up liquid circulation.
- Carefully place the water block onto the CPU, aligning the mounting holes.
- Secure the water block with the appropriate screws and fasteners, tightening them in a diagonal pattern until snug. Do not overtighten.
4.4 Connect Cables
- Connect the fan PWM cables to your motherboard's CPU_FAN or SYS_FAN headers. The fans operate between 800-1800 RPM, adjusting speed based on temperature.
- Connect the pump power cable (3-pin or SATA) to an available header on your motherboard or power supply.
- Connect the ARGB (5v-3pin) lighting cables from the fans and pump to your motherboard's ARGB header or a dedicated RGB controller.

5. Operating Instructions
Once installed, the Aigo ACSE liquid cooler operates automatically to maintain optimal CPU temperatures.
5.1 Fan Operation
The 120mm PWM fans adjust their speed dynamically between 800-1800 RPM based on the CPU temperature. This ensures higher airflow when cooling is needed and lower noise levels during lighter loads.

5.2 RGB Lighting
The fans and pump feature intelligent aurora RGB color-changing effects. If connected to a compatible motherboard ARGB header (5v-3pin), you can control and synchronize the lighting effects using your motherboard's software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). If no ARGB header is available, the lighting will typically cycle through default effects.
6. Maintenance
The Aigo ACSE liquid cooler is designed to be maintenance-free. There is no need to add water or cold liquid throughout its lifespan. However, regular cleaning of the radiator fins and fan blades can help maintain optimal cooling performance.
6.1 Cleaning
- Periodically check the radiator fins and fan blades for dust buildup.
- Use compressed air or a soft brush to gently remove dust from the radiator and fans. Ensure the fans are not spinning during cleaning to prevent damage.
- Wipe down the water block and tubes with a soft, dry cloth if necessary.
7. Troubleshooting
If you encounter issues with your Aigo ACSE liquid cooler, refer to the following common problems and solutions:
7.1 High CPU Temperatures
- Check Fan/Pump Connections: Ensure all fan and pump cables are securely connected to the correct headers on your motherboard or power supply.
- Verify Thermal Paste Application: Confirm that thermal paste was applied correctly and evenly between the CPU and water block.
- Radiator Airflow: Ensure the radiator is not obstructed by dust or cables, and that case airflow is adequate.
- Pump Operation: Listen for the pump operating. If you hear unusual noises or no sound, the pump might be faulty.
7.2 Fans Not Spinning or Making Noise
- Cable Connection: Check fan power cables (4-pin PWM) are securely connected.
- Fan Obstruction: Ensure no cables or objects are interfering with fan rotation.
- Unusual Noise: If a fan is making excessive noise, it might be defective. Contact support for replacement options.
7.3 RGB Lighting Issues
- ARGB Connection: Verify the 5v-3pin ARGB cable is correctly connected to your motherboard's ARGB header or controller. Ensure it's not connected to a 12V RGB header, which can cause damage.
- Software Control: If using motherboard software for RGB control, ensure it's up-to-date and correctly configured.
- No Synchronization: If you cannot synchronize with Aura Sync or similar software, double-check the physical connection and ensure the software detects the device.
7.4 Leaks or Physical Damage
- Immediate Action: If you observe any liquid leaks, immediately power off your system and disconnect power.
- Contact Support: For any leaks, physical damage (e.g., a loose internal component in the water block), or suspected defects, contact Aigo customer support.
8. User Tips
- Check Compatibility: Always verify your CPU socket (e.g., LGA 1200, LGA 1700, AM4) and case dimensions before purchasing and installing to ensure proper fit and function. The ACSE series supports a wide range of Intel and AMD sockets.
- ARGB vs. RGB: The Aigo ACSE series uses Addressable RGB (A-RGB) with a 5v-3pin connector. Ensure your motherboard has a compatible 5v-3pin ARGB header for software control. Do not connect to a 12V-4pin RGB header.
- Fan Replacement: If a fan becomes noisy or fails, contact Aigo customer support or authorized resellers for replacement fans. While the unit is maintenance-free, individual fan components may be replaceable.
- Thermal Paste: The included thermal paste is sufficient for installation. For enthusiasts, higher-performance aftermarket thermal pastes can be used, but are not strictly necessary for typical operation.
9. Warranty and Support
